[PVE-User] WG: Strange LVM problem

[Eneko Lacunza]

It's an IBM x3400 server with an Adaptec AAC-RAID (Rocket) (rev 02). LVM
is on a logical volume. 2.6.32 sees sda/sdb raid volumes, and last
running 2.6.35 also saw the same.

I will check next time we reboot that machine with 2.6.35 for scsi disk
names, thanks for the suggestion!
