[linux-lvm] RAID Failure Problems

[Matt Schillinger]

I recently had a RAID disk failure, which, due to a firmware bug, a
second drive went down.. Anyway, the data is being rebuilt (via RAID
Controller) now. It is online, but when i do a vgscan, i now only see 2
of the 4 volumes that were setup.  I am using reiserfs on all
filesystems affected.

Anyway, for lvm, i have simply used: 'pvcreate /dev/sda' (for the
/dev/sda). In other words, I didn't fdisk and set to Linux LVM. From
what I've seen, this so far has caused no problems.  Anyway, now, when i
do a vgscan, i only see 2 of the volumes.  When I do a pvdata /dev/sda
(one of the PVs not showing up), i get what looks like corrupted
naming..

[root at thor root]# pvdata /dev/sda

Segmentation fault

Is there a way I can fix this?

Thanks for all your help,
