LVM / Device Mapper maps wrong device
- by DaDaDom
Hi,
I run a LVM setup on a raid1 created by mdadm. md2 is based on sda6 (major:minor 8:6) and sdb6 (8:22). md2 is partition 9:2. The VG on top of md2 has 4 LVs, var, home, usr, tmp.
First the problem: While booting it seems as if the device mapper takes the wrong partition for the mapping! Immediately after boot the information is like
~# dmsetup table
systemlvm-home: 0 4194304 linear 8:22 384
systemlvm-home: 4194304 16777216 linear 8:22 69206400

~# cat /proc/mdstat
Personalities : [raid1]
md2 : active (auto-read-only) raid1 sda6[0]
151798080 blocks [2/1] [U_]
md0 : active raid1 sda1[0] sdb1[1]
96256 blocks [2/2] [UU]
md1 : active raid1 sda2[0] sdb2[1]
2931776 blocks [2/2] [UU]
I have to manually "lvchange -an" all LVs, add /dev/sdb6 back to the raid and reactivate the LVs, then all is fine. But it prevents me from automounting the partitions and obviously leads to a bunch of other problems.
If everything works fine, the information is like
~$ cat /proc/mdstat

md2 : active raid1 sdb6[1] sda6[0]

I think that LVM for some reason just "takes" /dev/sdb6 which is then missing in the raid. I tried almost all options in the lvm.conf but none seems to work.
Below is some more information, like config files. Does anyone have any idea about what is going on here and how to prevent that?
If you need any additional information, please let me know
Thanks in advance!
