Description Jes Sorensen 2012-04-27 13:47:11 UTC
Description of problem:
Rebuild does not continue after reboot. After reboot RAID volume is in normal
state, but rebuild did not finished and data is inconsistent (out-of-sync).

Version-Release number of selected component (if applicable):
mdadm 3.2.3-6.el6 and 3.2.3-7.el6

How reproducible:
Always

Steps to Reproduce:
1. Create IMSM container:
   # mdadm -C /dev/md/imsm -amd -e imsm -n 2 /dev/sdb /dev/sdc -R
2. Create RAID1 (of size at least 20G):
   # mdadm -C /dev/md/raid -amd -l1 -n 2 /dev/sdb /dev/sdc -R -f
   # mdadm --wait /dev/md/raid
3. Add spare disk to the container:
   # mdadm --add /dev/md127 /dev/sdd
4. Turn off HDD /dev/sdb
5. Wait for start of rebuild
6. Save config file:
   # mdadm -Ebs > /etc/mdadm.conf
7. Reboot system
8. Enter OROM and check whether the volume "raid" is in Rebuild state 
OR
9. Boot system and check whether rebuild process is going on.

Actual results:
In OROM the volume is in Normal state and rebuild seems to be finished.
After system's start-up RAID volume is in auto-read-only state and metadata is
in Dirty state. Rebuild seems to be finished but it is not. Data is
inconsistent (out-of-sync).

Expected results:
Rebuild continues and correctly finishes.

Additional info:
The bug occured after applying the patch "mdadm-2.5.2-static.patch" from
mdadm-3.2.3-6.el6.x86_64.rpm, which changes the path of mdmon's pid file
(MDMON_DIR) in Makefile.



The patch has been accepted by Neil and is upstream now:
