[linux-lvm] Problem with LVM2 and device-mapper

[linux-lvm] Problem with LVM2 and device-mapper

[Patrick Lawrence (LVM List)]

Hello,

I am using CentOS 4 and just did an upgrade from 4.1 to 4.2 on my x86_64
home server.  After a reboot, one of my vol groups stopped working.
It's a volume group spread across 2 disks and when I try to activate
that volgroup I get the following:

<snip>
[root@hetfield mapper]# vgchange -ay VolGroup02
   device-mapper ioctl cmd 9 failed: Invalid argument
   Couldn't load device 'VolGroup02-DVD'.
   1 logical volume(s) in volume group "VolGroup02" now active
<snip>

and the relevant portion of the /var/log/messages has:

<snip>
Oct 17 08:45:07 hetfield kernel: device-mapper: dm-linear: Device lookup
failed
Oct 17 08:45:07 hetfield kernel: device-mapper: error adding target to
table
<snip>

My other two volgroups are working fine.  It's just this third one that 
has problems.

I did quite a bit of googling yesterday, but I didn't come up with much 
although I have to confess that I know jack about the device mapper...

Is there anything I can provide to diagnose the problem further?  Since
CentOS tracks RHEL4 very closely, I suspect this affects RHEL4 as well.

Regards,

Pat

After a failed vgchange -ay, what does 'dmsetup ls' report?

I thought I've seen something like this in the past, but it always had 
to do with a partial load of a logical volume.

The node is indeed created in /dev/mapper (which I assume 'dmsetup ls'
is querying.)  If I deactivate that volgroup the entry is removed.

Hope this helps.

  Got the some problem after upgrade too.
For me it was "/sbin/dmraid -i -a y" in /etc/rc.d/rc.sysinit
which grab and lock somehow PV on PDC (hmmm. RAID card).
I don't know how it happend in details but looks like
"rpm -e dmraid" should help.
