Subject: [RHEL8.2 PATCH 52/61] imsm: return correct uuid for volume in detail
Fixes the side effect of the patch b6180160f ("imsm: save current_vol number")
- wrong UUID is printed in detail for each volume.
New parameter "subarray" is added to determine what info should be extracted
from metadata (subarray or container).
The parameter affects only IMSM metadata.

Subject: [RHEL8.2 PATCH 53/61] imsm: Change the way of printing nvme drives in
detail-platform.
Change NVMe controller path to device node path
in mdadm --detail-platform and print serial number.
The method imsm_read_serial always trimes serial to
MAX_RAID_SERIAL_LEN, added parameter 'serial_buf_len'
will be used to check the serial fit
to passed buffor, if not, will be trimed.

Date: Mon, 4 Nov 2019 14:27:49 +1100
Subject: [RHEL8.2 PATCH 54/61] Create: add support for RAID0 layouts.
Since Linux 5.4 a layout is needed for RAID0 arrays with
varying device sizes.
This patch makes the layout of an array visible (via --examine)
and sets the layout on newly created arrays.
--layout=dangerous
can be used to avoid setting a layout so that they array
can be used on older kernels.

In commit 039b7225e6 ("md: allow creation of mdNNN arrays via

was added. Special warning, when kernel is unable to handle
request, was added in commit 7105228e19
("mdadm/mdopen: create new function create_named_array for
writing to new_array"), but it was not adequate enough,
because in this situation mdadm tries to do it in old way.
This commit changes warning to be more relevant when
creating RAID container with "/dev/mdNNN" name and mdadm
back to old approach.

Subject: [RHEL8.2 PATCH 61/61] imsm: fill working_disks according to metadata.
Imsm tracks as "working_disk" each visible drive.
Assemble routine expects that the value will return count
of active member drives recorded in metadata.
As a side effect "--no-degraded" doesn't work correctly for imsm.
Align this field to others.
Added check, if the option --no-degraded is called with --scan.

Subject: [RHEL7.9 PATCH 62/77] mdadm.8: add note information for raid0 growing
operation
When growing a raid0 device, if the new component disk size is not
big enough, the grow operation may fail due to lack of backup space.
The minimum backup space should be larger than:
LCM(old, new) * chunk-size * 2
where LCM() is the least common multiple of the old and new count of
component disks, and "* 2" comes from the fact that mdadm refuses to
use more than half of a spare device for backup space.
There are users reporting such failure when they grew a raid0 array
with small component disk. Neil Brown points out this is not a bug
and how the failure comes. This patch adds note information into
mdadm(8) man page in the Notes part of GROW MODE section to explain
the minimum size requirement of new component disk size or external
backup size.

Subject: [RHEL7.9 PATCH 70/77] udev: Ignore change event for imsm
When adding a device to a container mdadm has to close its file
descriptor before sysfs_add_disk(). This generates change event.
There is race possibility because metadata is already written and other
-I process can place drive differently. As a result device can be added
to two containers simultaneously.
From IMSM perspective there is no need to react for change event. IMSM
doesn't support stacked devices.

Subject: [RHEL7.9 PATCH 71/77] Monitor: improve check_one_sharer() for
checking duplicated process
When running mdadm monitor with scan mode, only one autorebuild process
is allowed. check_one_sharer() checks duplicated process by following
steps,
1) Read autorebuild.pid file,
- if file does not exist, no duplicated process, go to 3).
- if file exists, continue to next step.
2) Read pid number from autorebuild.pid file, then check procfs pid
directory /proc/<PID>,
- if the directory does not exist, no duplicated process, go to 3)
- if the directory exists, print error message for duplicated process
and exit this mdadm.
3) Write current pid into autorebuild.pid file, continue to monitor in
scan mode.
The problem for the above step 2) is, if after system reboots and
another different process happens to have exact same pid number which
autorebuild.pid file records, check_one_sharer() will treat it as a
duplicated mdadm process and returns error with message "Only one
autorebuild process allowed in scan mode, aborting".
This patch tries to fix the above same-pid-but-different-process issue
by one more step to check the process command name,
1) Read autorebuild.pid file
- if file does not exist, no duplicated process, go to 4).
- if file exists, continue to next step.
2) Read pid number from autorebuild.pid file, then check procfs file
comm with the specific pid directory /proc/<PID>/comm
- if the file does not exit, it means the directory /proc/<PID> does
not exist, go to 4)
- if the file exits, continue next step
3) Read process command name from /proc/<PIC>/comm, compare the command
name with "mdadm" process name,
- if not equal, no duplicated process, goto 4)
- if strings are equal, print error message for duplicated process
and exit this mdadm.
4) Write current pid into autorebuild.pid file, continue to monitor in
scan mode.
Now check_one_sharer() returns error for duplicated process only when
the recorded pid from autorebuild.pid exists, and the process has exact
same command name as "mdadm".

Subject: [RHEL7.9 PATCH 73/77] Manage, imsm: Write metadata before add
New drive in container always appears as spare. Manager is able to
handle that, and queues appropriative update to monitor.
No update from mdadm side has to be processed, just insert the drive and
ping the mdmon. Metadata has to be written if no mdmon is running (case
for Raid0 or container without arrays).
If bare drive is added very early on startup (by custom bare rule),
there is possiblity that mdmon was not restarted after switch root. Old
one is not able to handle new drive. New one fails because there is
drive without metadata in container and metadata cannot be loaded.
To prevent this, write spare metadata before adding device
to container. Mdmon will overwrite it (same case as spare migration,
if drive appears it writes the most recent metadata).
Metadata has to be written only on new drive before sysfs_add_disk(),
don't race with mdmon if running.

Subject: [RHEL7.9 PATCH 74/77] Assemble: print error message if mdadm fails
assembling with --uuid option
When mdadm tries to assemble one working device and one zeroed-out device,
it failed but print successful message because there is --uuid option.
Following script always reproduce it.
dd if=/dev/zero of=/dev/ram0 oflag=direct
dd if=/dev/zero of=/dev/ram1 oflag=direct
./mdadm -C /dev/md111 -e 1.2 --uuid="12345678:12345678:12345678:12345678" \
-l1 -n2 /dev/ram0 /dev/ram1
./mdadm -S /dev/md111
dd if=/dev/zero of=/dev/ram1 oflag=direct
./mdadm -A /dev/md111 --uuid="12345678:12345678:12345678:12345678" \
/dev/ram0 /dev/ram1
Following is message from mdadm.
mdadm: No super block found on /dev/ram1 (Expected magic a92b4efc, got 00000000)
mdadm: no RAID superblock on /dev/ram1
mdadm: /dev/md111 assembled from 1 drive - need all 2 to start it (use --run to insist).
The mdadm say that it assembled but mdadm does not create /dev/md111.
The message is wrong.
After applying this patch, mdadm reports error correctly as following.
mdadm: No super block found on /dev/ram1 (Expected magic a92b4efc, got 00000000)
mdadm: no RAID superblock on /dev/ram1
mdadm: /dev/ram1 has no superblock - assembly aborted

Subject: [RHEL7.9 PATCH 76/77] Assemble.c: respect force flag.
If the array is dirty handler will set resync_start to 0 to inform kernel
that resync is needed. RWH affects only raid456 module, for other
levels array will be started even array is degraded and resync cannot be
performed.
Force is really meaningful for raid456. If array is degraded and resync
is requested, kernel will reject an attempt to start the array. To
respect force, it has to be marked as clean (this will be done for each
array without PPL) and remove the resync request (only for raid 456).
Data corruption may occur so proper warning is added.

Currently mdcheck (when called with `--duration`) logs only the

completion.
So, log the completion, too, so that it can be determined how long the
raid check took.
