Early Kdump HOWTO
|
||||
|
||||
Introduction
|
||||
------------
|
||||
|
||||
Early kdump is a mechanism to make kdump operational earlier than normal kdump
|
||||
service. The kdump service starts early enough for general crash cases, but
|
||||
there are some cases where it has no chance to make kdump operational in boot
|
||||
sequence, such as detecting devices and starting early services. If you hit
|
||||
such a case, early kdump may allow you to get more information of it.
|
||||
|
||||
Early kdump is implemented as a dracut module. It adds a kernel (vmlinuz) and
|
||||
initramfs for kdump to your system's initramfs in order to load them as early
|
||||
as possible. After that, if you provide "rd.earlykdump" in kernel command line,
|
||||
then in the initramfs, early kdump will load those files like the normal kdump
|
||||
service. This is disabled by default.
|
||||
|
||||
For the normal kdump service, it can check whether the early kdump has loaded
|
||||
the crash kernel and initramfs. It has no conflict with the early kdump.
|
||||
|
||||
How to configure early kdump
|
||||
----------------------------
|
||||
|
||||
We assume if you're reading this document, you should already have kexec-tools
|
||||
installed.
|
||||
|
||||
You can rebuild the initramfs with earlykdump support with below steps:
|
||||
|
||||
1. start kdump service to make sure kdump initramfs is created.
|
||||
|
||||
# systemctl start kdump
|
||||
|
||||
NOTE: If a crash occurs during boot process, early kdump captures a vmcore
|
||||
and reboot the system by default, so the system might go into crash loop.
|
||||
You can avoid such a crash loop by adding the following settings, which
|
||||
power off the system after dump capturing, to kdump.conf in advance:
|
||||
|
||||
final_action poweroff
|
||||
failure_action poweroff
|
||||
|
||||
For the failure_action, you can choose anything other than "reboot".
|
||||
|
||||
2. rebuild system initramfs with earlykdump support.
|
||||
|
||||
# dracut --force --add earlykdump
|
||||
|
||||
NOTE: Recommend to backup the original system initramfs before performing
|
||||
this step to put it back if something happens during boot-up.
|
||||
|
||||
3. add rd.earlykdump in grub kernel command line.
|
||||
|
||||
After making said changes, reboot your system to take effect. Of course, if you
|
||||
want to disable early kdump, you can simply remove "rd.earlykdump" from kernel
|
||||
boot parameters in grub, and reboot system like above.
|
||||
|
||||
Once the boot is completed, you can check the status of the early kdump support
|
||||
on the command prompt:
|
||||
|
||||
# journalctl -b | grep early-kdump
|
||||
|
||||
Then, you will see some useful logs, for example:
|
||||
|
||||
- if early kdump is successful.
|
||||
|
||||
Mar 09 09:57:56 localhost dracut-cmdline[190]: early-kdump is enabled.
|
||||
Mar 09 09:57:56 localhost dracut-cmdline[190]: kexec: loaded early-kdump kernel
|
||||
|
||||
- if early kdump is disabled.
|
||||
|
||||
Mar 09 10:02:47 localhost dracut-cmdline[189]: early-kdump is disabled.
|
||||
|
||||
Notes
|
||||
-----
|
||||
|
||||
- The size of early kdump initramfs will be large because it includes vmlinuz
|
||||
and kdump initramfs.
|
||||
|
||||
- Early kdump inherits the settings of normal kdump, so any changes that
|
||||
caused normal kdump rebuilding also require rebuilding the system initramfs
|
||||
to make sure that the changes take effect for early kdump. Therefore, after
|
||||
the rebuilding of kdump initramfs is completed, provide a prompt message to
|
||||
tell the fact.
|
||||
|
||||
- If you install an updated kernel and reboot the system with it, the early
|
||||
kdump will be disabled by default. To enable it with the new kernel, you
|
||||
need to take the above steps again.
|
||||
|
||||
Limitation
|
||||
----------
|
||||
|
||||
- At present, early kdump doesn't support fadump.
|
||||
|
||||
- Early kdump loads a crash kernel and initramfs at the beginning of the
|
||||
process in system's initramfs, so a crash at earlier than that (e.g. in
|
||||
kernel initialization) cannot be captured even with the early kdump.

Firmware assisted dump (fadump) HOWTO
|
||||
|
||||
Introduction
|
||||
|
||||
Firmware assisted dump is a new feature in the 3.4 mainline kernel supported
|
||||
only on powerpc architecture. The goal of firmware-assisted dump is to enable
|
||||
the dump of a crashed system, and to do so from a fully-reset system, and to
|
||||
minimize the total elapsed time until the system is back in production use. A
|
||||
complete documentation on implementation can be found at
|
||||
Documentation/powerpc/firmware-assisted-dump.txt in upstream linux kernel tree
|
||||
from 3.4 version and above.
|
||||
|
||||
Please note that the firmware-assisted dump feature is only available on Power6
|
||||
and above systems with recent firmware versions.
|
||||
|
||||
Overview
|
||||
|
||||
Fadump
|
||||
|
||||
Fadump is a robust kernel crash dumping mechanism to get reliable kernel crash
|
||||
dump with assistance from firmware. This approach does not use kexec, instead
|
||||
firmware assists in booting the kdump kernel while preserving memory contents.
|
||||
Unlike kdump, the system is fully reset, and loaded with a fresh copy of the
|
||||
kernel. In particular, PCI and I/O devices are reinitialized and are in a
|
||||
clean, consistent state. This second kernel, often called a capture kernel,
|
||||
boots with very little memory and captures the dump image.
|
||||
|
||||
The first kernel registers the sections of memory with the Power firmware for
|
||||
dump preservation during OS initialization. These registered sections of memory
|
||||
are reserved by the first kernel during early boot. When a system crashes, the
|
||||
Power firmware fully resets the system, preserves all the system memory
|
||||
contents, save the low memory (boot memory of size larger of 5% of system
|
||||
RAM or 256MB) of RAM to the previous registered region. It will also save
|
||||
system registers, and hardware PTE's.
|
||||
|
||||
Fadump is supported only on ppc64 platform. The standard kernel and capture
|
||||
kernel are one and the same on ppc64.
|
||||
|
||||
If you're reading this document, you should already have kexec-tools
|
||||
installed. If not, you install it via the following command:
|
||||
|
||||
# yum install kexec-tools
|
||||
|
||||
Fadump Operational Flow:
|
||||
|
||||
Like kdump, fadump also exports the ELF formatted kernel crash dump through
|
||||
/proc/vmcore. Hence existing kdump infrastructure can be used to capture fadump
|
||||
vmcore. The idea is to keep the functionality transparent to end user. From
|
||||
user perspective there is no change in the way kdump init script works.
|
||||
|
||||
However, unlike kdump, fadump does not pre-load kdump kernel and initrd into
|
||||
reserved memory, instead it always uses default OS initrd during second boot
|
||||
after crash. Hence, for fadump, we rebuild the new kdump initrd and replace it
|
||||
with default initrd. Before replacing existing default initrd we take a backup
|
||||
of original default initrd for user's reference. The dracut package has been
|
||||
enhanced to rebuild the default initrd with vmcore capture steps. The initrd
|
||||
image is rebuilt as per the configuration in /etc/kdump.conf file.
|
||||
|
||||
The control flow of fadump works as follows:
|
||||
01. System panics.
|
||||
02. At the crash, kernel informs power firmware that kernel has crashed.
|
||||
03. Firmware takes the control and reboots the entire system preserving
|
||||
only the memory (resets all other devices).
|
||||
04. The reboot follows the normal booting process (non-kexec).
|
||||
05. The boot loader loads the default kernel and initrd from /boot
|
||||
06. The default initrd loads and runs /init
|
||||
07. dracut-kdump.sh script present in fadump aware default initrd checks if
|
||||
'/proc/device-tree/rtas/ibm,kernel-dump' file exists before executing
|
||||
steps to capture vmcore.
|
||||
(This check will help to bypass the vmcore capture steps during normal boot
|
||||
process.)
|
||||
09. Captures dump according to /etc/kdump.conf
|
||||
10. Is dump capture successful (yes goto 12, no goto 11)
|
||||
11. Perform the failure action specified in /etc/kdump.conf
|
||||
(The default failure action is reboot, if unspecified)
|
||||
12. Perform the final action specified in /etc/kdump.conf
|
||||
(The default final action is reboot, if unspecified)
|
||||
|
||||
|
||||
How to configure fadump:
|
||||
|
||||
Again, we assume if you're reading this document, you should already have
|
||||
kexec-tools installed. If not, you install it via the following command:
|
||||
|
||||
# yum install kexec-tools
|
||||
|
||||
Make the kernel to be configured with FADump as the default boot entry, if
|
||||
it isn't already:
|
||||
|
||||
# grubby --set-default=/boot/vmlinuz-<kver>
|
||||
|
||||
Boot into the kernel to be configured for FADump. To be able to do much of
|
||||
anything interesting in the way of debug analysis, you'll also need to install
|
||||
the kernel-debuginfo package, of the same arch as your running kernel, and the
|
||||
crash utility:
|
||||
|
||||
# yum --enablerepo=\*debuginfo install kernel-debuginfo.$(uname -m) crash
|
||||
|
||||
Next up, we need to modify some boot parameters to enable firmware assisted
|
||||
dump. With the help of grubby, it's very easy to append "fadump=on" to the end
|
||||
of your kernel boot parameters. To reserve the appropriate amount of memory
|
||||
for boot memory preservation, pass 'crashkernel=X' kernel cmdline parameter.
|
||||
For the recommended value of X, see 'FADump Memory Requirements' section.
|
||||
|
||||
# grubby --args="fadump=on crashkernel=6G" --update-kernel=/boot/vmlinuz-`uname -r`
|
||||
|
||||
By default, FADump reserved memory will be initialized as CMA area to make the
|
||||
memory available through CMA allocator on the production kernel. We can opt out
|
||||
of this, making reserved memory unavailable to production kernel, by booting the
|
||||
linux kernel with 'fadump=nocma' instead of 'fadump=on'.
|
||||
|
||||
The term 'boot memory' means size of the low memory chunk that is required for
|
||||
a kernel to boot successfully when booted with restricted memory. By default,
|
||||
the boot memory size will be the larger of 5% of system RAM or 256MB.
|
||||
Alternatively, user can also specify boot memory size through boot parameter
|
||||
'fadump_reserve_mem=' which will override the default calculated size. Use this
|
||||
option if default boot memory size is not sufficient for second kernel to boot
|
||||
successfully.
|
||||
|
||||
After making said changes, reboot your system, so that the specified memory is
|
||||
reserved and left untouched by the normal system. Take note that the output of
|
||||
'free -m' will show X MB less memory than without this parameter, which is
|
||||
expected. If you see OOM (Out Of Memory) error messages while loading capture
|
||||
kernel, then you should bump up the memory reservation size.
|
||||
|
||||
Now that you've got that reserved memory region set up, you want to turn on
|
||||
the kdump init script:
|
||||
|
||||
# systemctl enable kdump.service
|
||||
|
||||
Then, start up kdump as well:
|
||||
|
||||
# systemctl start kdump.service
|
||||
|
||||
This should turn on the firmware assisted functionality in kernel by
|
||||
echo'ing 1 to /sys/kernel/fadump_registered, leaving the system ready
|
||||
to capture a vmcore upon crashing. For journaling filesystems like XFS an
|
||||
additional step is required to ensure bootloader does not pick the
|
||||
older initrd (without vmcore capture scripts):
|
||||
|
||||
* If /boot is a separate partition, run the below commands as the root user,
|
||||
or as a user with CAP_SYS_ADMIN rights:
|
||||
|
||||
# fsfreeze -f
|
||||
# fsfreeze -u
|
||||
|
||||
* If /boot is not a separate partition, reboot the system.
|
||||
|
||||
After reboot check if the kdump service is up and running with:
|
||||
|
||||
# systemctl status kdump.service
|
||||
|
||||
To test out whether FADump is configured properly, you can force-crash your
|
||||
system by echo'ing a 'c' into /proc/sysrq-trigger:
|
||||
|
||||
# echo c > /proc/sysrq-trigger
|
||||
|
||||
You should see some panic output, followed by the system reset and booting into
|
||||
fresh copy of kernel. When default initrd loads and runs /init, vmcore should
|
||||
be copied out to disk (by default, in /var/crash/<YYYY.MM.DD-HH:MM:SS>/vmcore),
|
||||
then the system rebooted back into your normal kernel.
|
||||
|
||||
Once back to your normal kernel, you can use the previously installed crash
|
||||
kernel in conjunction with the previously installed kernel-debuginfo to
|
||||
perform postmortem analysis:
|
||||
|
||||
# crash /usr/lib/debug/lib/modules/2.6.17-1.2621.el5/vmlinux
|
||||
/var/crash/2006-08-23-15:34/vmcore
|
||||
|
||||
crash> bt
|
||||
|
||||
and so on...
|
||||
|
||||
Saving vmcore-dmesg.txt
|
||||
-----------------------
|
||||
Kernel log bufferes are one of the most important information available
|
||||
in vmcore. Now before saving vmcore, kernel log bufferes are extracted
|
||||
from /proc/vmcore and saved into a file vmcore-dmesg.txt. After
|
||||
vmcore-dmesg.txt, vmcore is saved. Destination disk and directory for
|
||||
vmcore-dmesg.txt is same as vmcore. Note that kernel log buffers will
|
||||
not be available if dump target is raw device.
|
||||
|
||||
FADump Memory Requirements:
|
||||
|
||||
System Memory Recommended memory
|
||||
--------------------- ----------------------
|
||||
4 GB - 16 GB : 768 MB
|
||||
16 GB - 64 GB : 1024 MB
|
||||
64 GB - 128 GB : 2 GB
|
||||
128 GB - 1 TB : 4 GB
|
||||
1 TB - 2 TB : 6 GB
|
||||
2 TB - 4 TB : 12 GB
|
||||
4 TB - 8 TB : 20 GB
|
||||
8 TB - 16 TB : 36 GB
|
||||
16 TB - 32 TB : 64 GB
|
||||
32 TB - 64 TB : 128 GB
|
||||
64 TB & above : 180 GB
|
||||
|
||||
Things to remember:
|
||||
|
||||
1) The memory required to boot capture Kernel is a moving target that depends
|
||||
on many factors like hardware attached to the system, kernel and modules in
|
||||
use, packages installed and services enabled, there is no one-size-fits-all.
|
||||
But the above recommendations are based on system memory. So, the above
|
||||
recommendations for FADump come with a few assumptions, based on available
|
||||
system memory, about the resources the system could have. So, please take
|
||||
the recommendations with a pinch of salt and remember to try capturing dump
|
||||
a few times to confirm that the system is configured successfully with dump
|
||||
capturing support.
|
||||
|
||||
2) Though the memory requirements for FADump seem high, this memory is not
|
||||
completely set aside but made available for userspace applications to use,
|
||||
through the CMA allocator.
|
||||
|
||||
3) As the same initrd is used for booting production kernel as well as capture
|
||||
kernel and with dump being captured in a restricted memory environment, few
|
||||
optimizations (like not inclding network dracut module, disabling multipath
|
||||
and such) are applied while building the initrd. In case, the production
|
||||
environment needs these optimizations to be avoided, dracut_args option in
|
||||
/etc/kdump.conf file could be leveraged. For example, if a user wishes for
|
||||
network module to be included in the initrd, adding the below entry in
|
||||
/etc/kdump.conf file and restarting kdump service would take care of it.
|
||||
|
||||
dracut_args --add "network"
|
||||
|
||||
4) If FADump is configured to capture vmcore to a remote dump target using SSH
|
||||
or NFS protocol, the corresponding network interface '<interface-name>' is
|
||||
renamed to 'kdump-<interface-name>', if it is generic (like *eth# or net#).
|
||||
It happens because vmcore capture scripts in the initial RAM disk (initrd)
|
||||
add the 'kdump-' prefix to the network interface name to secure persistent
|
||||
naming. And as capture kernel and production kernel use the same initrd in
|
||||
case of FADump, the interface name is changed for the production kernel too.
|
||||
This is likely to impact network configuration setup for production kernel.
|
||||
So, it is recommended to use a non-generic name for a network interface,
|
||||
before setting up FADump to capture vmcore to a remote dump target based on
|
||||
that network interface, to avoid running into network configuration issues.
|
||||
|
||||
Dump Triggering methods:
|
||||
|
||||
This section talks about the various ways, other than a Kernel Panic, in which
|
||||
fadump can be triggered. The following methods assume that fadump is configured
|
||||
on your system, with the scripts enabled as described in the section above.
|
||||
|
||||
1) AltSysRq C
|
||||
|
||||
FAdump can be triggered with the combination of the 'Alt','SysRq' and 'C'
|
||||
keyboard keys. Please refer to the following link for more details:
|
||||
|
||||
https://fedoraproject.org/wiki/QA/Sysrq
|
||||
|
||||
In addition, on PowerPC boxes, fadump can also be triggered via Hardware
|
||||
Management Console(HMC) using 'Ctrl', 'O' and 'C' keyboard keys.
|
||||
|
||||
2) Kernel OOPs
|
||||
|
||||
If we want to generate a dump everytime the Kernel OOPses, we can achieve this
|
||||
by setting the 'Panic On OOPs' option as follows:
|
||||
|
||||
# echo 1 > /proc/sys/kernel/panic_on_oops
|
||||
|
||||
3) PowerPC specific methods:
|
||||
|
||||
On IBM PowerPC machines, issuing a soft reset invokes the XMON debugger(if
|
||||
XMON is configured). To configure XMON one needs to compile the kernel with
|
||||
the CONFIG_XMON and CONFIG_XMON_DEFAULT options, or by compiling with
|
||||
CONFIG_XMON and booting the kernel with xmon=on option.
|
||||
|
||||
Following are the ways to remotely issue a soft reset on PowerPC boxes, which
|
||||
would drop you to XMON. Pressing a 'X' (capital alphabet X) followed by an
|
||||
'Enter' here will trigger the dump.
|
||||
|
||||
3.1) HMC
|
||||
|
||||
Hardware Management Console(HMC) available on Power4 and Power5 machines allow
|
||||
partitions to be reset remotely. This is specially useful in hang situations
|
||||
where the system is not accepting any keyboard inputs.
|
||||
|
||||
Once you have HMC configured, the following steps will enable you to trigger
|
||||
fadump via a soft reset:
|
||||
|
||||
On Power4
|
||||
Using GUI
|
||||
|
||||
* In the right pane, right click on the partition you wish to dump.
|
||||
* Select "Operating System->Reset".
|
||||
* Select "Soft Reset".
|
||||
* Select "Yes".
|
||||
|
||||
Using HMC Commandline
|
||||
|
||||
# reset_partition -m <machine> -p <partition> -t soft
|
||||
|
||||
On Power5
|
||||
Using GUI
|
||||
|
||||
* In the right pane, right click on the partition you wish to dump.
|
||||
* Select "Restart Partition".
|
||||
* Select "Dump".
|
||||
* Select "OK".
|
||||
|
||||
Using HMC Commandline
|
||||
|
||||
# chsysstate -m <managed system name> -n <lpar name> -o dumprestart -r lpar
|
||||
|
||||
3.2) Blade Management Console for Blade Center
|
||||
|
||||
To initiate a dump operation, go to Power/Restart option under "Blade Tasks" in
|
||||
the Blade Management Console. Select the corresponding blade for which you want
|
||||
to initate the dump and then click "Restart blade with NMI". This issues a
|
||||
system reset and invokes xmon debugger.
|
||||
|
||||
|
||||
Advanced Setups & Failure action:
|
||||
|
||||
Kdump and fadump exhibit similar behavior in terms of setup & failure action.
|
||||
For fadump advanced setup related information see section "Advanced Setups" in
|
||||
"kexec-kdump-howto.txt" document. Refer to "Failure action" section in "kexec-
|
||||
kdump-howto.txt" document for fadump failure action related information.
|
||||
|
||||
Compression and filtering
|
||||
|
||||
Refer "Compression and filtering" section in "kexec-kdump-howto.txt" document.
|
||||
Compression and filtering are same for kdump & fadump.
|
||||
|
||||
|
||||
Notes on rootfs mount:
|
||||
Dracut is designed to mount rootfs by default. If rootfs mounting fails it
|
||||
will refuse to go on. So fadump leaves rootfs mounting to dracut currently.
|
||||
We make the assumtion that proper root= cmdline is being passed to dracut
|
||||
initramfs for the time being. If you need modify "KDUMP_COMMANDLINE=" in
|
||||
/etc/sysconfig/kdump, you will need to make sure that appropriate root=
|
||||
options are copied from /proc/cmdline. In general it is best to append
|
||||
command line options using "KDUMP_COMMANDLINE_APPEND=" instead of replacing
|
||||
the original command line completely.
|
||||
|
||||
How to disable FADump:
|
||||
|
||||
Remove "fadump=on"/"fadump=nocma" from kernel cmdline parameters OR replace
|
||||
it with "fadump=off" kernel cmdline parameter:
|
||||
|
||||
# grubby --update-kernel=/boot/vmlinuz-`uname -r` --remove-args="fadump=on"
|
||||
or
|
||||
# grubby --update-kernel=/boot/vmlinuz-`uname -r` --remove-args="fadump=nocma"
|
||||
OR
|
||||
# grubby --update-kernel=/boot/vmlinuz-`uname -r` --args="fadump=off"
|
||||
|
||||
If KDump is to be used as the dump capturing mechanism, update the crashkernel
|
||||
parameter (Else, remove "crashkernel=" parameter too, using grubby):
|
||||
|
||||
# grubby --update-kernel=/boot/vmlinuz-$kver --args="crashkernl=auto"
|
||||
|
||||
Reboot the system for the settings to take effect.

# - Will mount -t <fs type> <partition> <mnt>, and copy
|
||||
# /proc/vmcore to <mnt>/<path>/%DATE/.
|
||||
# NOTE: <partition> can be a device node, label or uuid.
|
||||
# It's recommended to use persistent device names
|
||||
# such as /dev/vg/<devname>.
|
||||
# Otherwise it's suggested to use label or uuid.
|
||||
#
|
||||
# path <path>
|
||||
# - "path" represents the file system path in which vmcore
|
||||
# will be saved. If a dump target is specified in
|
||||
# kdump.conf, then "path" is relative to the specified
|
||||
# dump target.
|
||||
#
|
||||
# Interpretation of "path" changes a bit if the user didn't
|
||||
# specify any dump target explicitly in kdump.conf. In this
|
||||
# case, "path" represents the absolute path from root. The
|
||||
# dump target and adjusted path are arrived at automatically
|
||||
# depending on what's mounted in the current system.
|
||||
#
|
||||
# Ignored for raw device dumps. If unset, will use the default
|
||||
# "/var/crash".
|
||||
#
|
||||
# core_collector <command> <options>
|
||||
# - This allows you to specify the command to copy
|
||||
# the vmcore. The default is makedumpfile, which on
|
||||
# some architectures can drastically reduce vmcore size.
|
||||
# See /sbin/makedumpfile --help for a list of options.
|
||||
# Note that the -i and -g options are not needed here,
|
||||
# as the initrd will automatically be populated with a
|
||||
# config file appropriate for the running kernel.
|
||||
# The default core_collector for raw/ssh dump is:
|
||||
# "makedumpfile -F -l --message-level 7 -d 31".
|
||||
# The default core_collector for other targets is:
|
||||
# "makedumpfile -l --message-level 7 -d 31".
|
||||
#
|
||||
# "makedumpfile -F" will create a flattened vmcore.
|
||||
# You need to use "makedumpfile -R" to rearrange the dump data to
|
||||
# a normal dumpfile readable with analysis tools. For example:
|
||||
# "makedumpfile -R vmcore < vmcore.flat".
|
||||
#
|
||||
# For core_collector format details, you can refer to
|
||||
# kexec-kdump-howto.txt or kdump.conf manpage.
|
||||
#
|
||||
# kdump_post <binary | script>
|
||||
# - This directive allows you to run a executable binary
|
||||
# or script after the vmcore dump process terminates.
|
||||
# The exit status of the current dump process is fed to
|
||||
# the executable binary or script as its first argument.
|
||||
# All files under /etc/kdump/post.d are collectively sorted
|
||||
# and executed in lexical order, before binary or script
|
||||
# specified kdump_post parameter is executed.
|
||||
#
|
||||
# kdump_pre <binary | script>
|
||||
# - Works like the "kdump_post" directive, but instead of running
|
||||
# after the dump process, runs immediately before it.
|
||||
# Exit status of this binary is interpreted as follows:
|
||||
# 0 - continue with dump process as usual
|
||||
# non 0 - run the final action (reboot/poweroff/halt)
|
||||
# All files under /etc/kdump/pre.d are collectively sorted and
|
||||
# executed in lexical order, after binary or script specified
|
||||
# kdump_pre parameter is executed.
|
||||
# Even if the binary or script in /etc/kdump/pre.d directory
|
||||
# returns non 0 exit status, the processing is continued.
|
||||
#
|
||||
# extra_bins <binaries | shell scripts>
|
||||
# - This directive allows you to specify additional binaries or
|
||||
# shell scripts to be included in the kdump initrd.
|
||||
# Generally they are useful in conjunction with a kdump_post
|
||||
# or kdump_pre binary or script which depends on these extra_bins.
|
||||
#
|
||||
# extra_modules <module(s)>
|
||||
# - This directive allows you to specify extra kernel modules
|
||||
# that you want to be loaded in the kdump initrd.
|
||||
# Multiple modules can be listed, separated by spaces, and any
|
||||
# dependent modules will automatically be included.
|
||||
#
|
||||
# failure_action <reboot | halt | poweroff | shell | dump_to_rootfs>
|
||||
# - Action to perform in case dumping fails.
|
||||
# reboot: Reboot the system.
|
||||
# halt: Halt the system.
|
||||
# poweroff: Power down the system.
|
||||
# shell: Drop to a bash shell.
|
||||
# Exiting the shell reboots the system by default,
|
||||
# or perform "final_action".
|
||||
# dump_to_rootfs: Dump vmcore to rootfs from initramfs context and
|
||||
# reboot by default or perform "final_action".
|
||||
# Useful when non-root dump target is specified.
|
||||
# The default option is "reboot".
|
||||
#
|
||||
# default <reboot | halt | poweroff | shell | dump_to_rootfs>
|
||||
# - Same as the "failure_action" directive above, but this directive
|
||||
# is obsolete and will be removed in the future.
|
||||
#
|
||||
# final_action <reboot | halt | poweroff>
|
||||
# - Action to perform in case dumping succeeds. Also performed
|
||||
# when "shell" or "dump_to_rootfs" failure action finishes.
|
||||
# Each action is same as the "failure_action" directive above.
|
||||
# The default is "reboot".
|
||||
#
|
||||
# force_rebuild <0 | 1>
|
||||
# - By default, kdump initrd will only be rebuilt when necessary.
|
||||
# Specify 1 to force rebuilding kdump initrd every time when kdump
|
||||
# service starts.
|
||||
#
|
||||
# force_no_rebuild <0 | 1>
|
||||
# - By default, kdump initrd will be rebuilt when necessary.
|
||||
# Specify 1 to bypass rebuilding of kdump initrd.
|
||||
#
|
||||
# force_no_rebuild and force_rebuild options are mutually
|
||||
# exclusive and they should not be set to 1 simultaneously.
|
||||
#
|
||||
# override_resettable <0 | 1>
|
||||
# - Usually an unresettable block device can't be a dump target.
|
||||
# Specifying 1 when you want to dump even though the block
|
||||
# target is unresettable
|
||||
# By default, it is 0, which will not try dumping destined to fail.
|
||||
#
|

# dracut_args <arg(s)>
|

# - Pass extra dracut options when rebuilding kdump initrd.
|

Kdump-in-cluster-environment HOWTO
|
||||
|
||||
Introduction
|
||||
|
||||
Kdump is a kexec based crash dumping mechansim for Linux. This docuement
|
||||
illustrate how to configure kdump in cluster environment to allow the kdump
|
||||
crash recovery service complete without being preempted by traditional power
|
||||
fencing methods.
|
||||
|
||||
Overview
|
||||
|
||||
Kexec/Kdump
|
||||
|
||||
Details about Kexec/Kdump are available in Kexec-Kdump-howto file and will not
|
||||
be described here.
|
||||
|
||||
fence_kdump
|
||||
|
||||
fence_kdump is an I/O fencing agent to be used with the kdump crash recovery
|
||||
service. When the fence_kdump agent is invoked, it will listen for a message
|
||||
from the failed node that acknowledges that the failed node is executing the
|
||||
kdump crash kernel. Note that fence_kdump is not a replacement for traditional
|
||||
fencing methods. The fence_kdump agent can only detect that a node has entered
|
||||
the kdump crash recovery service. This allows the kdump crash recovery service
|
||||
complete without being preempted by traditional power fencing methods.
|
||||
|
||||
fence_kdump_send
|
||||
|
||||
fence_kdump_send is a utility used to send messages that acknowledge that the
|
||||
node itself has entered the kdump crash recovery service. The fence_kdump_send
|
||||
utility is typically run in the kdump kernel after a cluster node has
|
||||
encountered a kernel panic. Once the cluster node has entered the kdump crash
|
||||
recovery service, fence_kdump_send will periodically send messages to all
|
||||
cluster nodes. When the fence_kdump agent receives a valid message from the
|
||||
failed nodes, fencing is complete.
|
||||
|
||||
How to configure Pacemaker cluster environment:
|
||||
|
||||
If we want to use kdump in Pacemaker cluster environment, fence-agents-kdump
|
||||
should be installed in every nodes in the cluster. You can achieve this via
|
||||
the following command:
|
||||
|
||||
# yum install -y fence-agents-kdump
|
||||
|
||||
Next is to add kdump_fence to the cluster. Assuming that the cluster consists
|
||||
of three nodes, they are node1, node2 and node3, and use Pacemaker to perform
|
||||
resource management and pcs as cli configuration tool.
|
||||
|
||||
With pcs it is easy to add a stonith resource to the cluster. For example, add
|
||||
a stonith resource named mykdumpfence with fence type of fence_kdump via the
|
||||
following commands:
|
||||
|
||||
# pcs stonith create mykdumpfence fence_kdump \
|
||||
pcmk_host_check=static-list pcmk_host_list="node1 node2 node3"
|
||||
# pcs stonith update mykdumpfence pcmk_monitor_action=metadata --force
|
||||
# pcs stonith update mykdumpfence pcmk_status_action=metadata --force
|
||||
# pcs stonith update mykdumpfence pcmk_reboot_action=off --force
|
||||
|
||||
Then enable stonith
|
||||
# pcs property set stonith-enabled=true
|
||||
|
||||
How to configure kdump:
|
||||
|
||||
Actually there are two ways how to configure fence_kdump support:
|
||||
|
||||
1) Pacemaker based clusters
|
||||
If you have successfully configured fence_kdump in Pacemaker, there is
|
||||
no need to add some special configuration in kdump. So please refer to
|
||||
Kexec-Kdump-howto file for more information.
|
||||
|
||||
2) Generic clusters
|
||||
For other types of clusters there are two configuration options in
|
||||
kdump.conf which enables fence_kdump support:
|
||||
|
||||
fence_kdump_nodes <node(s)>
|
||||
Contains list of cluster node(s) separated by space to send
|
||||
fence_kdump notification to (this option is mandatory to enable
|
||||
fence_kdump)
|
||||
|
||||
fence_kdump_args <arg(s)>
|
||||
Command line arguments for fence_kdump_send (it can contain
|
||||
all valid arguments except hosts to send notification to)
|
||||
|
||||
These options will most probably be configured by your cluster software,
|
||||
so please refer to your cluster documentation how to enable fence_kdump
|
||||
support.
|
||||
|
||||
Please be aware that these two ways cannot be combined and 2) has precedence
|
||||
over 1). It means that if fence_kdump is configured using fence_kdump_nodes
|
||||
and fence_kdump_args options in kdump.conf, Pacemaker configuration is not
|
||||
used even if it exists.

#
|

# The logger defined 4 logging levels:
|
||||
# - ddebug (4)
|
||||
# The DEBUG Level designates fine-grained informational events that are most
|
||||
# useful to debug an application.
|
||||
# - dinfo (3)
|
||||
# The INFO level designates informational messages that highlight the
|
||||
# progress of the application at coarse-grained level.
|
||||
# - dwarn (2)
|
||||
# The WARN level designates potentially harmful situations.
|
||||
# - derror (1)
|
||||
# The ERROR level designates error events that might still allow the
|
||||
# application to continue running.
|
||||
#
|
||||
# Logging is controlled by following global variables:
|
||||
# - @var kdump_stdloglvl - logging level to standard error (console output)
|
||||
# - @var kdump_sysloglvl - logging level to syslog (by logger command)
|
||||
# - @var kdump_kmsgloglvl - logging level to /dev/kmsg (only for boot-time)
|
||||
#
|
||||
# If any of the variables is not set, the function dlog_init() sets it to default:
|
||||
# - In the first kernel:
|
||||
# - @var kdump_stdloglvl = 3 (info)
|
||||
# - @var kdump_sysloglvl = 0 (no logging)
|
||||
# - @var kdump_kmsgloglvl = 0 (no logging)
|

#

# - @var kdump_sysloglvl = 3 (info)
|

# - @var kdump_kmsgloglvl = 0 (no logging)

|
||||
.SH NAME
|
||||
kdump.conf \- configuration file for kdump kernel.
|
||||
|
||||
.SH DESCRIPTION
|
||||
|
||||
kdump.conf is a configuration file for the kdump kernel crash
|
||||
collection service.
|
||||
|
||||
kdump.conf provides post-kexec instructions to the kdump kernel. It is
|
||||
stored in the initrd file managed by the kdump service. If you change
|
||||
this file and do not want to reboot in order for the changes to take
|
||||
effect, restart the kdump service to rebuild the initrd.
|
||||
|
||||
For most configurations, you can simply review the examples provided
|
||||
in the stock /etc/kdump.conf.
|
||||
|
||||
.B NOTE:
|
||||
For filesystem dumps the dump target must be mounted before building
|
||||
kdump initramfs.
|
||||
|
||||
kdump.conf only affects the behavior of the initramfs. Please read the
|
||||
kdump operational flow section of kexec-kdump-howto.txt in the docs to better
|
||||
understand how this configuration file affects the behavior of kdump.
|
||||
|
||||
.SH OPTIONS
|
||||
|
||||
.B raw <partition>
|
||||
.RS
|
||||
Will dd /proc/vmcore into <partition>. Use persistent device names for
|
||||
partition devices, such as /dev/vg/<devname>.
|
||||
.RE
|
||||
|
||||
.B nfs <nfs mount>
|
||||
.RS
|
||||
Will mount nfs to <mnt>, and copy /proc/vmcore to <mnt>/<path>/%HOST-%DATE/,
|
||||
supports DNS. Note that a fqdn should be used as the server name in the
|
||||
mount point.
|
||||
.RE
|
||||
|
||||
.B ssh <user@server>
|
||||
.RS
|
||||
Will scp /proc/vmcore to <user@server>:<path>/%HOST-%DATE/,
|
||||
supports DNS. NOTE: make sure user has necessary write permissions on
|
||||
server and that a fqdn is used as the server name.
|
||||
.RE
|
||||
|
||||
.B sshkey <path>
|
||||
.RS
|
||||
Specify the path of the ssh key to use when dumping via ssh.
|
||||
The default value is /root/.ssh/kdump_id_rsa.
|
||||
.RE
|
||||
|
||||
.B <fs type> <partition>
|
||||
.RS
|
||||
Will mount -t <fs type> <partition> <mnt>, and copy /proc/vmcore to
|
||||
<mnt>/<path>/%DATE/. NOTE: <partition> can be a device node, label
|
||||
or uuid. It's recommended to use persistent device names such as
|
||||
/dev/vg/<devname>. Otherwise it's suggested to use label or uuid.
|
||||
.RE
|
||||
|
||||
.B path <path>
|
||||
.RS
|
||||
"path" represents the file system path in which vmcore will be saved.
|
||||
If a dump target is specified in kdump.conf, then "path" is relative to the
|
||||
specified dump target.
|
||||
.PP
|
||||
Interpretation of "path" changes a bit if the user didn't specify any dump
|
||||
target explicitly in kdump.conf. In this case, "path" represents the
|
||||
absolute path from root. The dump target and adjusted path are arrived
|
||||
at automatically depending on what's mounted in the current system.
|
||||
.PP
|
||||
Ignored for raw device dumps. If unset, will use the default "/var/crash".
|
||||
.RE
|
||||
|
||||
.B core_collector <command> <options>
|
||||
.RS
|
||||
This allows you to specify the command to copy the vmcore.
|
||||
The default is makedumpfile, which on some architectures can drastically reduce
|
||||
core file size. See /sbin/makedumpfile --help for a list of options.
|
||||
Note that the -i and -g options are not needed here, as the initrd
|
||||
will automatically be populated with a config file appropriate
|
||||
for the running kernel.
|
||||
.PP
|
||||
Note 1: About default core collector:
|
||||
The default core_collector for raw/ssh dump is:
|
||||
"makedumpfile -F -l --message-level 7 -d 31".
|
||||
The default core_collector for other targets is:
|
||||
"makedumpfile -l --message-level 7 -d 31".
|
||||
Even if core_collector option is commented out in kdump.conf, makedumpfile
|
||||
is the default core collector and kdump uses it internally.
|
||||
If one does not want makedumpfile as default core_collector, then they
|
||||
need to specify one using core_collector option to change the behavior.
|
||||
.PP
|
||||
Note 2: If "makedumpfile -F" is used then you will get a flattened format
|
||||
vmcore.flat, you will need to use "makedumpfile -R" to rearrange the
|
||||
dump data from standard input to a normal dumpfile (readable with analysis
|
||||
tools).
|
||||
ie. "makedumpfile -R vmcore < vmcore.flat"
|
||||
.PP
|
||||
Note 3: If specified core_collector simply copy the vmcore file to the
|
||||
dump target (eg: cp, scp), the vmcore could be significantly large.
|
||||
Please make sure the dump target has enough space, at leaset larger
|
||||
than the system's RAM.
|
||||
|
||||
.RE
|
||||
|
||||
.B kdump_post <binary | script>
|
||||
.RS
|
||||
This directive allows you to run a specified executable
|
||||
just after the vmcore dump process terminates. The exit
|
||||
status of the current dump process is fed to the kdump_post
|
||||
executable as its first argument($1). Executable can modify
|
||||
it to indicate the new exit status of succeeding dump process,
|
||||
.PP
|
||||
All files under /etc/kdump/post.d are collectively sorted
|
||||
and executed in lexical order, before binary or script
|
||||
specified kdump_post parameter is executed.
|
||||
.PP
|
||||
Note that scripts written for use with this directive must use the /bin/bash
|
||||
interpreter. And since these scripts run in kdump enviroment, the reference to
|
||||
the storage or network device in the scripts should adhere to the section
|
||||
\'Supported dump target types and requirements\' in kexec-kdump-howto.txt.
|
||||
|
||||
.RE
|
||||
|
||||
.B kdump_pre <binary | script>
|
||||
.RS
|
||||
Works just like the "kdump_post" directive, but instead
|
||||
of running after the dump process, runs immediately
|
||||
before. Exit status of this binary is interpreted
|
||||
as follows:
|
||||
.PP
|
||||
0 - continue with dump process as usual
|
||||
.PP
|
||||
non 0 - run the final action (reboot/poweroff/halt)
|
||||
.PP
|
||||
All files under /etc/kdump/pre.d are collectively sorted and
|
||||
executed in lexical order, after binary or script specified
|
||||
kdump_pre parameter is executed.
|
||||
Even if the binary or script in /etc/kdump/pre.d directory
|
||||
returns non 0 exit status, the processing is continued.
|
||||
.PP
|
||||
Note that scripts written for use with this directive must use the /bin/bash

interpreter. And since these scripts run in kdump enviroment, the reference to

.B extra_bins <binaries | shell scripts>
|

.RS
|

This directive allows you to specify additional
|

binaries or shell scripts you'd like to include in
|
||||
your kdump initrd. Generally only useful in
|
||||
conjunction with a kdump_post binary or script that

relies on other binaries or scripts.
|

.RE
|
||||
|
||||
.B extra_modules <module(s)>
|
||||
.RS
|
||||
This directive allows you to specify extra kernel
|
||||
modules that you want to be loaded in the kdump
|
||||
initrd, typically used to set up access to
|
||||
non-boot-path dump targets that might otherwise
|
||||
not be accessible in the kdump environment. Multiple
|
||||
modules can be listed, separated by spaces, and any
|

dependent modules will automatically be included.

.RE
|

|
||||
.B failure_action <reboot | halt | poweroff | shell | dump_to_rootfs>
|
||||
.RS
|
||||
Action to perform in case dumping to the intended target fails. The default is "reboot".
|
||||
reboot: Reboot the system (this is what most people will want, as it returns the system
|
||||
to a normal state). halt: Halt the system and lose the vmcore. poweroff: The system
|
||||
will be powered down. shell: Drop to a shell session inside the initramfs, from which
|
||||
you can manually perform additional recovery actions. Exiting this shell reboots the
|
||||
system by default or performs "final_action".
|
||||
Note: kdump uses bash as the default shell. dump_to_rootfs: If non-root dump
|
||||
target is specified, the failure action can be set as dump_to_rootfs. That means when
|
||||
dumping to target fails, dump vmcore to rootfs from initramfs context and reboot
|
||||
by default or perform "final_action".

.RE
|
||||

.B default <reboot | halt | poweroff | shell | dump_to_rootfs>

Usually an unresettable block device can't be a dump target. Specifying 1 means

By default, it's set to 0, which will not try something destined to fail.

blacklist option was recently being used to prevent loading modules in

initramfs. General terminology for blacklist has been that module is

retaining blacklist option creates more confusing behavior. It has been

deprecated.

Instead, use rd.driver.blacklist option on second kernel to blacklist

a certain module. One can edit /etc/sysconfig/kdump and edit

.SH EXAMPLES
|
||||
Here are some examples for core_collector option:
|
||||
.PP
|
||||
Core collector command format depends on dump target type. Typically for
|
||||
filesystem (local/remote), core_collector should accept two arguments.
|
||||
First one is source file and second one is target file. For ex.
|
||||
.TP
|
||||
ex1.
|
||||
core_collector "cp --sparse=always"
|
||||
|
||||
Above will effectively be translated to:
|
||||
|
||||
cp --sparse=always /proc/vmcore <dest-path>/vmcore
|
||||
.TP
|
||||
ex2.
|
||||
core_collector "makedumpfile -l --message-level 7 -d 31"
|
||||
|
||||
Above will effectively be translated to:
|
||||
|
||||
makedumpfile -l --message-level 7 -d 31 /proc/vmcore <dest-path>/vmcore
|
||||
.PP
|
||||
For dump targets like raw and ssh, in general, core collector should expect
|
||||
one argument (source file) and should output the processed core on standard
|
||||
output (There is one exception of "scp", discussed later). This standard
|
||||
output will be saved to destination using appropriate commands.
|
||||
|
||||
raw dumps examples:
|
||||
.TP
|
||||
ex3.
|
||||
core_collector "cat"
|
||||
|
||||
Above will effectively be translated to.
|
||||
|
||||
cat /proc/vmcore | dd of=<target-device>
|
||||
.TP
|
||||
ex4.
|
||||
core_collector "makedumpfile -F -l --message-level 7 -d 31"
|
||||
|
||||
Above will effectively be translated to.
|
||||
|
||||
makedumpfile -F -l --message-level 7 -d 31 | dd of=<target-device>
|
||||
.PP
|
||||
ssh dumps examples
|
||||
.TP
|
||||
ex5.
|
||||
core_collector "cat"
|
||||
|
||||
Above will effectively be translated to.
|
||||
|
||||
cat /proc/vmcore | ssh <options> <remote-location> "dd of=path/vmcore"
|
||||
.TP
|
||||
ex6.
|
||||
core_collector "makedumpfile -F -l --message-level 7 -d 31"
|
||||
|
||||
Above will effectively be translated to.
|
||||
|
||||
makedumpfile -F -l --message-level 7 -d 31 | ssh <options> <remote-location> "dd of=path/vmcore"
|
||||
|
||||
There is one exception to standard output rule for ssh dumps. And that is
|
||||
scp. As scp can handle ssh destinations for file transfers, one can
|
||||
specify "scp" as core collector for ssh targets (no output on stdout).
|
||||
.TP
|
||||
ex7.
|
||||
core_collector "scp"
|
||||
|
||||
Above will effectively be translated to.

Subject: [PATCH] [PATCH] sadump: fix failure of reading memory when 5-level
|
||||
paging is enabled
|
||||
|
||||
makedumpfile fails as follows for memory dumps collected by sadump
|
||||
when 5-level paging is enabled on the corresponding systems:
|
||||
|
||||
# makedumpfile -l -d 31 -x ./vmlinux ./dump.sadump dump.sadump-ld31
|
||||
__vtop4_x86_64: Can't get a valid pgd.
|
||||
...snip...
|
||||
__vtop4_x86_64: Can't get a valid pgd.
|
||||
calc_kaslr_offset: failed to calculate kaslr_offset and phys_base; default to 0
|
||||
__vtop4_x86_64: Can't get a valid pgd.
|
||||
readmem: Can't convert a virtual address(ffffffff82fce960) to physical address.
|
||||
readmem: type_addr: 0, addr:ffffffff82fce960, size:1024
|
||||
cpu_online_mask_init: Can't read cpu_online_mask memory.
|
||||
|
||||
makedumpfile Failed.
|
||||
|
||||
This is because 5-level paging support has not been done yet for
|
||||
sadump; the work of the 5-level paging support was done by the commit
|
||||
30a3214a7193e94c551c0cebda5918a72a35c589 (PATCH 4/4 arch/x86_64: Add
|
||||
5-level paging support) but that was focused on the core part only.
|
||||
|
||||
Having said that, most of things has already been finished in the
|
||||
commit. What needs to be newly added for sadump is just how to check
|
||||
if 5-level paging is enabled for a given memory dump.
|
||||
|
||||
For that purpose, let's refer to CR4.LA57, bit 12 of CR4, representing
|
||||
whether 5-level paging is enabled or not. We can do this because
|
||||
memory dumps collected by sadump have SMRAM as note information and
|
||||
they include CR4 together with the other control registers.

|

Kdump now works on live images with some manual configurations. Here is the step
|
||||
by step guide.
|
||||
|
||||
1. Enable crashkernel reservation
|
||||
|
||||
Since there isn't any config file that can be used to configure kernel
|
||||
parameters for live images before booting them, we have to append 'crashkernel'
|
||||
argument in boot menu every time we boot a live image.
|
||||
|
||||
2. Change dump target in /etc/kdump.conf
|
||||
|
||||
When kdump kernel boots in a live environment, the default target /var/crash is
|
||||
in RAM so you need to change the dump target to an external disk or a network
|
||||
dump target.
|
||||
|
||||
Besides, make sure that "default dump_to_rootfs" is not specified.
|
||||
|
||||
3. Start kdump service
|
||||
|
||||
$ kdumpctl start
|
||||
|
||||
4. Trigger a kdump test
|
||||
|
||||
$ echo 1 > /proc/sys/kernel/sysrq
|
||||
$ echo c > /proc/sysrq-trigger

.TH MKDUMRD 8 "Fri Feb 9 2007"
|
||||
.SH NAME
|
||||
mkdumprd \- creates initial ramdisk images for kdump crash recovery
|
||||
.SH SYNOPSIS
|
||||
\fBmkdumprd\fR [OPTION]
|
||||
|
||||
.SH DESCRIPTION
|
||||
\fBmkdumprd\fR creates an initial ram file system for use in conjunction with
|
||||
the booting of a kernel within the kdump framework for crash recovery.
|
||||
\fBmkdumprds\fR purpose is to create an initial ram filesystem capable of copying
|
||||
the crashed systems vmcore image to a location specified in \fI/etc/kdump.conf
|
||||
|
||||
\fBmkdumprd\fR interrogates the running system to understand what modules need to
|
||||
be loaded in the initramfs (based on configuration retrieved from
|
||||
\fI/etc/kdump.conf)\fR
|
||||
|
||||
\fBmkdumprd\fR add a new \fBdracut\fR module 99kdumpbase and use \fBdracut\fR
|
||||
utility to generate the initramfs. When generating a kdump initramfs, \fBmkdumprd\fR
|
||||
will determine how much disk space is available, if the dump target's available
|
||||
space is not greater than the total system memory, \fBmkdumprd\fR will print a
|
||||
warning to remind that there might not be enough space to save a vmcore. The
|
||||
warning covers extreme scenarios such as the slab explodes with non-zero data or
|
||||
a full vmcore, etc. Therefore, need to prevent users from having minimum disk
|
||||
space for crash dump.
|
||||
|
||||
\fBmkdumprd\fR was not intended for casual use outside of the service
|
||||
initialization script for the kdump utility, and should not be run manually. If
|
||||
you require a custom kdump initramfs image, it is suggested that you use the
|
||||
kdump service infrastructure to create one, and then manually unpack, modify and
|
||||
repack the image.
|
||||
|
||||
|
||||
.SH OPTIONS

||||

Subject: [PATCH] Fix eppic issue with hardening flags
|

|

This is stash of two commits:

||||

||||

|
||||
Tell gcc not to omit frame pointer
|
||||
|
||||
After commit 0209874, it's now possible to enable optimization above O0.
|
||||
But eppic might call __builtin_return_address(1). With O1,
|
||||
-fomit-frame-pointer is enabled gcc may omit frame pointer.
|
||||
__builtin_return_address(1) relies on callee preserves RBP as the stack
|
||||
base, which is untrue if optimization is usded. In this case it may return
|
||||
wrong value or crash.
|
||||
|
||||
In case of any potential failure, use -fno-omit-frame-pointer globally.

Supported Kdump Targets
|
||||
|
||||
This document try to list all supported kdump targets, and those supported
|
||||
or unknown/tech-preview targets, this can help users to decide whether a dump
|
||||
solution is available.
|
||||
|
||||
Dump Target support status
|
||||
==========================
|
||||
This section tries to come up with some kind of guidelines in terms of
|
||||
what dump targets are supported/not supported. Whatever is listed here
|
||||
is not binding in any manner. It is just sharing of current understanding
|
||||
and if something is not right, this section needs to be edited.
|
||||
|
||||
Following are 3 lists. First one contains supported targets. These are
|
||||
generic configurations which should work and some configuration most
|
||||
likely has worked in testing. Second list is known unsupported targets.
|
||||
These targets we know either don't work or we don't support. And third
|
||||
list is unknown/tech-preview. We either don't yet know the status of kdump
|
||||
on these targets or these are under tech-preview.
|
||||
|
||||
Note, these lists are not set in stone and can be changed at any point of
|
||||
time. Also these lists might not be complete. We will add/remove items to
|
||||
it as we get more testing information. Also, there are many corner cases
|
||||
which can't possibly be listed. For example in general we might be
|
||||
supporting software iscsi but there might be some configurations of it
|
||||
which don't work.
|
||||
|
||||
So if any target is listed in supported section, it does not mean it works
|
||||
in all possible configurations. It just means that in common configurations
|
||||
it should work but there can be issues with particular configurations which
|
||||
are not supported. As we come to know of particular issues, we will keep on
|
||||
updating lists accordingly.

Note on FCoE
|
||||
=====================
|
||||
If you are trying to dump to a software FCoE target, you may encounter OOM
|
||||
issue, because some software FCoE requires more memory to work. In such case,
|
||||
you may need to increase the kdump reserved memory size in "crashkernel="
|
||||
kernel parameter.
|
||||
|
||||
By default, RHEL systems have "crashkernel=auto" in kernel boot arguments.
|
||||
The auto reserved memory size is designed to balance the coverage of use cases
|
||||
and an acceptable memory overhead, so not every use case could fit in, software
|
||||
FCoE is one of the case.
|
||||
|
||||
For hardware FCoE, kdump should work naturally as firmware will do the
|
||||
initialization job. The capture kernel and kdump tools will run just fine.

Kexec Kdump Self-test
|
||||
=====================
|
||||
|
||||
|
||||
Introduction
|
||||
============
|
||||
The self-tests here are useful for quick sanity tests for new patches, and also helpful for debugging issues.
|
||||
|
||||
|
||||
How it works
|
||||
============
|
||||
All tests are run within VMs using qemu. By default, VM images are based on Fedora Cloud image, and the image for each test run is a layered qcow2 snapshot on top of the base image.
|
||||
Test images are managed by Makefile, so if there are any code change in the kexec-tools repository, `make` command will detect that and only rebuild the top image layer. This makes the test runs boot fast and each test run is clean.
|
||||
|
||||
|
||||
Basic usage
|
||||
===========
|
||||
Before you start, you can make the self-tests use your own base image by running following command:
|
||||
|
||||
`make clean && make BASE_IMAGE=<path/to/your/image>`
|
||||
|
||||
This is helpful if you have a slow network, else self-test will try to download the cloud image from Fedora's official website using `wget`.
|
||||
|
||||
- Use the following command to run all tests:
|
||||
$ make test-run
|
||||
|
||||
All available tests will be executed.
|
||||
|
||||
Test artifacts are stored in output/<testcase>
|
||||
|
||||
- For easier debugging, you can run only on test with the following command:
|
||||
$ make TEST_CASE=<testcase> test-run
|
||||
|
||||
This way, VM's console is directly connected to stdin/out so debugging will be easier.
|
||||
If there are multiple VMs used in a test case, the VM performing actual kdump/kexec operation will be connected to stdin/out.
|
||||
|
||||
Test Cases
|
||||
==========
|
||||
Each test case is a folder under scripts/testcases/, a test case folder will contain at least one executable shell script, and each script should contain two functions: "on_build" and "on_test".
|
||||
|
||||
"on_build" is called when building the test image, which can instruct the self-test framework to install packages or create files, etc.
|
||||
"on_test" is called when VM finished booting, which can get the boot count by calling "get_test_boot_count" and determine what to do. It should call "test_passed" on success, and call "test_failed" on failure. "test_aborted" is called when unexpected behavior occurs.
|
||||
|
||||
When there are multiple scripts in a single test case folder, they will spawn VMs in lexical order, and the last VM is considered the VM performing the actual test. Other VMs could be hosting test required service. This is useful for the network dump test. However, "test_passed" or "test_failed" or "test_aborted" could be called in any of these VMs, so during network kdump test, the dump target can also terminate the test and mark it passed when a valid vmcore is detected.
|
||||
|
||||
|
||||
Debugging
|
||||
=========
|
||||
|
||||
- When the test VM boots, you can append "no_test" to kernel args in grub, which tells the test services to quit early.
|
||||
|
||||
- You can launch the VMs manually or inspect the image after ran a test.
|
||||
|
||||
Test images are located as:
|
||||
|
||||
output/<testcase>/<vm-name>.img
|
||||
|
||||
Test images' corresponding qemu command are located as:
|
||||
|
||||
output/<testcase>/<vm-name>.qemu_cmd
|
||||
|
||||
To repeat/debug a test manually, you should launch all VMs in output/<testcase> menu in lexical order, and append 'no_test' in the last VM's grub cmdline, then VM will hang on login prompt, login with root/fedora. Test script is located as /kexec-kdump-test/test.sh
|
||||
|
||||
- If you just want to inspect the images file content, you can also use scripts/spawn-image-shell.sh <test-image> to spawn a shell in the image quickly.
