Hi:

Doing some tests with software RAID in Linux I have had a problem when
trying to re-add a formerly (manually) failed and then removed drive
from a two-disk software RAID1 (mirror). Be warned that the problem
occurred with a kernel tainted by VMware's binary modules. I have tried
to reproduce the problem again with and without those modules loaded,
but these times everything worked as expected.

* Base configuration
- Vanilla Linux kernel version 2.4.20 plus XFS patches applied and
compiled XFS as a module, but not loaded
- raidtools2 version 1.00.3-2 (Debian Sid)
- mdadm version 1.2.0-1 (Debian Sid)

* RAID configuration (raidtools2 format)

raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 4

device /dev/Grupo00/Crecimiento
raid-disk 0

device /dev/Grupo00/Suplemento
raid-disk 1

lvscan -- ACTIVE "/dev/Grupo00/Crecimiento" [224 MB]
lvscan -- ACTIVE "/dev/Grupo00/Suplemento" [224 MB]

--- Volume group ---
VG Name Grupo00
VG Access read/write
VG Status available/resizable

Partition Table for /dev/hdc (only PV in VG is /dev/hdc2)
First Last
# Type Sector Sector Offset Length Filesystem Type (ID)
# Flags
-- ------- -------- --------- ------ --------- -------------------------------
1 Primary 0 6136829 63 6136830 HPFS/NTFS (07) None (00)
2 Primary 6136830 12659219 0 6522390 Linux LVM (8E) None (00)

* Steps leading to the problem

1. Create the array (using either mdadm or mkraid)
mdadm --create /dev/md0 --chunk=4 --level=1 --raid-devices=2 \
/dev/Grupo00/Crecimiento /dev/Grupo00/Suplemento
mkraid /dev/md0 (using the /etc/raidtab show above)
2. Create a filesystem on the RAID1 device and mount it somewhere
mke2fs /dev/md0 ; mount -t ext2 /dev/md0 /mnt/tests
3. Populate it with some data
cp -Rvp /etc/ /mnt/tests
4. Check array reconstruction is over (/proc/mdstat)

...and now for the real problem...

5. Generate some I/O load on the device
while :; do ls -lR /mnt/tests ; done

6. Fail one of the devices (works OK, as seen on /proc/mdstat)
mdadm --manage /dev/md0 --fail /dev/Grupo00/Crecimiento
Personalities : [raid1]
read_ahead 1024 sectors
md0 : active raid1 Grupo00/Suplemento[1]
229312 blocks [2/1] [_U]

7. Remove the failed device from the array (works OK)
mdadm --manage /dev/md0 --remove /dev/Grupo00/Crecimiento

8. Shortly afterwards, re-add the same device to the same array (fails)
mdadm --manage /dev/md0 --add /dev/Grupo00/Crecimiento

The process hangs: "ps" shows the following:
1 0 15251 1 -1 -20 0 0 ? SW< ? 0:00 [raid1d]
4 0 16885 14558 9 0 1248 300 rwsem_ D pts/2 0:00 mdadm --manage /dev/md0 --add /dev/Grupo00/Crecimiento

"mdadm" gets blocked waiting for data at "rwsem_down_read_failed". A
subsequent attempt to access the RAID device fails. For example:
mdadm --misc --detail /dev/md0
gives us a process...
4 0 17586 16933 9 0 1252 300 down_i S pts/1 0:00 mdadm --misc --detail /dev/md0
... that never ends "blocked" in down_interruptible

Via "SysRq+T" we get a listing of processes and their stacks, that
feeded through "ksymoops" gives us the following _complete_ dump:

ksymoops 2.4.8 on i686 2.4.20-xfs. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.20-xfs/ (default)
-m /boot/System.map-2.4.20-xfs (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

Trying to reboot the box, the device cannot be unmounted, and during
runlevel 6, at "sending all processes the TERM signal...", the console
shows the followin message:
md: ioctl lock interrupted, reason -4, cmd -2142762735

SysRq+S cannot sync the device, neither SysRq+U works, and the box is
rebooted via SysRq+B. During startup, the messages from RAID
initialization are show on the console:

The array starts in degraded mode, but with no other apparent problems
so far. Trying to add the drive to the array now works OK, both with and
without heavy I/O to the array, and both with and without VMware binary
modeles loaded.

As previously said, I could not reproduce the bug more times, but if
there is more information needed or would like me to do some tests,
please ask.

Hope this helps.
