Subject: [RHEL7.7 PATCH 01/24] Assemble: keep MD_DISK_FAILFAST and
|
||||||
|
MD_DISK_WRITEMOSTLY flag
|
||||||
|
|
||||||
|
Before updating superblock of slave disks, desired_state value
|
||||||
|
is set for the target state of the slave disks. But it forgets
|
||||||
|
to check MD_DISK_FAILFAST and MD_DISK_WRITEMOSTLY flags. Then
|
||||||
|
start_arrays() calls ADD_NEW_DISK ioctl-call and pass the state
|
||||||
|
without MD_DISK_FAILFAST and MD_DISK_WRITEMOSTLY.
|
||||||
|
|
||||||
|
Currenlty it does not generate any problem because kernel does not
|
||||||
|
care MD_DISK_FAILFAST or MD_DISK_WRITEMOSTLY flags.

|
||||||
|
|
||||||
|
PART-POLICY has been accepted in mdadm.conf since the same
|
||||||
|
time that POLICY was accepted, but it was never documented.
|
||||||
|
So add the missing documentation.
|
||||||
|
|
||||||
|
Also fix a bug which would have stopped it from working if
|
||||||
|
anyone had ever tried to use it.

Subject: [RHEL7.7 PATCH 03/24] policy: support devices with multiple paths.
|
||||||
|
|
||||||
|
As new releases of Linux some time change the name of
|
||||||
|
a path, some distros keep "legacy" names as well. This
|
||||||
|
is useful, but confuses mdadm which assumes each device has
|
||||||
|
precisely one path.
|
||||||
|
|
||||||
|
So change this assumption: allow a disk to have several
|
||||||
|
paths, and allow any to match when looking for a policy
|
||||||
|
which matches a disk.

Subject: [RHEL7.7 PATCH 04/24] mdcheck: add systemd unit files to run mdcheck.
|
||||||
|
|
||||||
|
Having the mdcheck script is not use if is never run.
|
||||||
|
This patch adds systemd unit files so that it can easily
|
||||||
|
be run on the first Sunday of each month for 6 hours,
|
||||||
|
then on every subsequent morning until the check is
|
||||||
|
finished.
|
||||||
|
|
||||||
|
The units still need to be enabled with
|
||||||
|
systemctl enable mdcheck_start.timer
|
||||||
|
|
||||||
|
The timer will only actually be started when an array
|
||||||
|
which might need it becomes active.

|
||||||
|
|
||||||
|
"mdadm --monitor --oneshot" can be used to get a warning
|
||||||
|
if there are any degraded arrays. It can be helpful to get
|
||||||
|
this warning periodically while the condition persists.
|
||||||
|
|
||||||
|
This patch add a systemd service and timer which can
|
||||||
|
be enabled with
|
||||||
|
systemctl enable mdmonitor-oneshot.service
|
||||||
|
|
||||||
|
and will then provide daily warnings.

Subject: [RHEL7.7 PATCH 06/24] imsm: update metadata correctly while raid10
|
||||||
|
double degradation
|
||||||
|
|
||||||
|
Mdmon calls end_migration() when map state changes from normal to
|
||||||
|
degraded. It is not valid because in raid 10 double degradation case
|
||||||
|
mdmon breaks checkpointing but array is still rebuilding.
|
||||||
|
In this case mdmon has to mark map as degraded and continues marking
|
||||||
|
recovery checkpoint in metadata. Migration can be finished only if newly
|
||||||
|
failed device is a rebuilding device.
|
||||||
|
|
||||||
|
Add catching double degraded to degraded transition. Migration is
|
||||||
|
finished but map state doesn't change, array is still degraded.
|
||||||
|
|
||||||
|
Update failed_disk_num correctly. If double degradation
|
||||||
|
happens rebuild will start on the lowest slot, but this variable points
|
||||||
|
to the first failed slot. If second fail happens while rebuild this
|
||||||
|
variable shouldn't be updated until rebuild is not finished.

|

|
With a chunk size of 16Meg and data drive count of 8,
|

|
this calculate can easily overflow the 'int' type that
|

|
is used for the multiplications.
|
||||||

So force it to use "long" instead.

Subject: [RHEL7.7 PATCH 12/24] imsm: finish recovery when drive with rebuild
|
||||||
|
fails
|
||||||
|
|
||||||
|
Commit d7a1fda2769b ("imsm: update metadata correctly while raid10 double
|
||||||
|
degradation") resolves main Imsm double degradation problems but it
|
||||||
|
omits one case. Now metadata hangs in the rebuilding state if the drive
|
||||||
|
under rebuild is removed during recovery from double degradation.
|
||||||
|
|
||||||
|
The root cause of this problem is comparing new map_state with current
|
||||||
|
and if they both are degraded assuming that nothing new happens.
|
||||||
|
|
||||||
|
Don't rely on map states, just check if device is failed. If the drive
|
||||||
|
under rebuild fails then finish migration, in other cases update map
|
||||||
|
state only (second fail means that destination map state can't be normal).
|
||||||
|
|
||||||
|
To avoid problems with reassembling move end_migration (called after
|
||||||
|
double degradation successful recovery) after check if recovery really
|
||||||
|
finished, for details see (7ce057018 "imsm: fix: rebuild does not
|
||||||
|
continue after reboot").
|
||||||
|
Remove redundant code responsible for finishing rebuild process. Function
|
||||||
|
end_migration do exactly the same. Set last_checkpoint to 0, to prepare
|
||||||
|
it for the next rebuild.

Subject: [RHEL7.7 PATCH 13/24] imsm: fix reshape for >2TB drives
|
||||||
|
|
||||||
|
If reshape is performed on drives larger then 2 TB,
|
||||||
|
migration checkpoint area that is calculated exeeds 32-bit value.
|
||||||
|
This checkpoint area is a reserved space threated as backup
|
||||||
|
during reshape - at the end of the drive, right before metadata.
|
||||||
|
As a result - wrong space is used and the data that may exists there
|
||||||
|
is overwritten.
|
||||||
|
|
||||||
|
Adding additional field to migration record to track high order 32-bits
|
||||||
|
of pba of this area. Three other fields that may exceed 32-bit value
|
||||||
|
for large drives are added as well.
|
||||||
|
|

Subject: [RHEL7.7 PATCH 15/24] Detail.c: do not skip first character when
|
||||||
|
calling xstrdup in Detail()
|
||||||
|
|
||||||
|
'Commit b9c9bd9bacaa ("Detail: ensure --export names are acceptable as
|
||||||
|
shell variables")' duplicates mdi->sys_name to sysdev string by,
|
||||||
|
char *sysdev = xstrdup(mdi->sys_name + 1);
|
||||||
|
which skips the first character of mdi->sys_name. Then when running
|
||||||
|
mdadm --detail <md device> --export, the output looks like,
|
||||||
|
MD_DEVICE_ev_sda2_ROLE=1
|
||||||
|
MD_DEVICE_ev_sda2_DEV=/dev/sda2
|
||||||
|
The first character of md device (between MD_DEVICE and _ROLE/_DEV)
|
||||||
|
is dropped. The expected output should be,
|
||||||
|
MD_DEVICE_dev_sda2_ROLE=1
|
||||||
|
MD_DEVICE_dev_sda2_DEV=/dev/sda2
|
||||||
|
|
||||||
|
This patch removes the '+ 1' from calling xstrdup() in Detail(), which
|
||||||
|
gets the dropped first character back.

Subject: [RHEL7.7 PATCH 16/24] Fix reshape for decreasing data offset
|
||||||
|
|
||||||
|
...when not changing the number of disks.
|
||||||
|
|
||||||
|
This patch needs context to explain. These are the relevant parts of
|
||||||
|
the original code (condensed and annotated):
|
||||||
|
|
||||||
|
if (dir > 0) {
|
||||||
|
/* Increase data offset (reshape backwards) */
|
||||||
|
if (data_offset < sd->data_offset + min) {
|
||||||
|
pr_err("--data-offset too small on %s\n",
|
||||||
|
dn);
|
||||||
|
goto release;
|
||||||
|
}
|
||||||
|
} else {
|
||||||
|
/* Decrease data offset (reshape forwards) */
|
||||||
|
if (data_offset < sd->data_offset - min) {
|
||||||
|
pr_err("--data-offset too small on %s\n",
|
||||||
|
dn);
|
||||||
|
goto release;
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
When this code is reached, mdadm has already decided on a reshape
|
||||||
|
direction. When increasing the data offset, the reshape runs backwards
|
||||||
|
(dir==1); when decreasing the data offset, the reshape runs forwards
|
||||||
|
(dir==-1).
|
||||||
|
|
||||||
|
The conditional within the backwards reshape is correct: the requested
|
||||||
|
offset must be larger than the old offset plus a minimum delta; thus the
|
||||||
|
reshape has room to work.
|
||||||
|
|
||||||
|
For the forwards reshape, the requested offset needs to be smaller than
|
||||||
|
the old offset minus a minimum delta; to do this correctly, the
|
||||||
|
comparison must be reversed.
|
||||||
|
|
||||||
|
Also update the error message.
|
||||||
|
|
||||||
|
Note: I have tested this change on a RAID 5 on Linux 4.18.0 and verified
|
||||||
|
that there were no errors from the kernel and that the device data
|
||||||
|
remained intact. I do not know if there are considerations for different
|
||||||
|
RAID levels.

Subject: [RHEL7.7 PATCH 18/24] mdmon: don't attempt to manage new arrays when
|
||||||
|
terminating
|
||||||
|
|
||||||
|
When mdmon gets a SIGTERM, it stops managing arrays that are clean. If
|
||||||
|
there is more that one array in the container and one of them is dirty
|
||||||
|
and the clean one is still present in mdstat, mdmon will treat it as a
|
||||||
|
new array and start managing it again. This leads to a cycle of
|
||||||
|
remove_old() / manage_new() calls for the clean array, until the other
|
||||||
|
one also becomes clean.
|
||||||
|
|
||||||
|
Prevent this by not calling manage_new() if sigterm is set. Also, remove
|
||||||
|
a check for sigterm in manage_new() because the condition will never be
|
||||||
|
true.

Subject: [RHEL7.7 PATCH 19/24] mdmon: wait for previous mdmon to exit during
|
||||||
|
takeover
|
||||||
|
|
||||||
|
Since the patch c76242c5("mdmon: get safe mode delay file descriptor
|
||||||
|
early"), safe_mode_dalay is set properly by initrd mdmon. But in some
|
||||||
|
cases with filesystem traffic since the very start of the system, it
|
||||||
|
might take a while to transit to clean state. Due to fact that new
|
||||||
|
mdmon does not wait for the old one to exit - it might happen that the
|
||||||
|
new one switches safe_mode_delay back to seconds, before old one exits.
|
||||||
|
As the result two mdmons are running concurrently on same array.
|
||||||
|
|
||||||
|
Wait for the old mdmon to exit by pinging it with SIGUSR1 signal, just
|
||||||
|
in case it is sleeping.

Subject: [RHEL7.7 PATCH 21/24] add missing units to --examine
|
||||||
|
|
||||||
|
Within the output of "mdadm --examine", there are three sizes reported
|
||||||
|
on adjacent lines. For example:
|
||||||
|
|
||||||
|
$ sudo mdadm --examine /dev/md3
|
||||||
|
[...]
|
||||||
|
Avail Dev Size : 17580545024 (8383.06 GiB 9001.24 GB)
|
||||||
|
Array Size : 17580417024 (16765.99 GiB 18002.35 GB)
|
||||||
|
Used Dev Size : 11720278016 (5588.66 GiB 6000.78 GB)
|
||||||
|
[...]
|
||||||
|
|
||||||
|
This can be confusing, since the first and third line are in 512-byte
|
||||||
|
sectors, and the second is in KiB.
|
||||||
|
|
||||||
|
Add units to avoid ambiguity.
|
||||||
|
|
||||||
|
(I don't particularly like the "KiB" notation, but it is at least
|
||||||
|
unambiguous.)

Subject: [RHEL7.7 PATCH 22/24] imsm: fix spare activation for old matrix
|
||||||
|
arrays
|
||||||
|
|
||||||
|
During spare activation get_extents() calculates metadata reserved space based
|
||||||
|
on smallest active RAID member or it will take the defaults. Since patch
|
||||||
|
611d9529("imsm: change reserved space to 4MB") default is extended. If array
|
||||||
|
was created prior that patch, reserved space is smaller. In case of matrix
|
||||||
|
RAID - spare is activated in each array one-by-one, so it is spare for first
|
||||||
|
activation, but treated as "active" during second one.
|
||||||
|
|
||||||
|
In case of adding spare drive to old matrix RAID with the size the same as
|
||||||
|
already existing member drive the routine will take the defaults during second
|
||||||
|
run and mdmon will refuse to rebuild second volume, claiming that the drive
|
||||||
|
does not have enough free space.
|
||||||
|
|
||||||
|
Add parameter to get_extents(), so the during spare activation reserved space
|
||||||
|
is always based on smallest active drive - even if given drive is already
|
||||||
|
active in some other array of matrix RAID.
