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:
[root at 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
and the relevant portion of the /var/log/messages has:
Oct 17 08:45:07 hetfield kernel: device-mapper: dm-linear: Device lookup
Oct 17 08:45:07 hetfield kernel: device-mapper: error adding target to
My other two volgroups are working fine. It's just this third one that
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.
