No error at all. How does the GParted Live-CD do that?

Are the LVM versions different?

Original system:

LVM version: 2.02.25 (2007-04 27)
Library version: 1.02.19 (2007-04-27)
Driver version: 4.11.0


RescueCD:

LVM version: 2.02.45 (2009-03-03)
Library version: 1.02.31 (2009-03-03)
Driver version: 4.14.0


They are in fact different. The problem is, they are running software that only runs until OpenSuSE 10.3.


This is something different. As the GParted Live-CD shows, the device
has the correct UUID. This means that, for whatever reason, LVM is not
scanning the correct device(s) to find a UUID.

When you boot the system normally, which device is the drive that LVM
can't find?

sdc

You may simply be missing the correct kernel module for the disk
controller.

How could I verify that?

If it is showing up as a device, you've got the right modules loaded.

No, it is not showing up in '/dev'.
So there's probably a driver/kernel module problem. Though the scsi drivers seem to be loaded. Have you seen the other posts with Per Jessen?


Disk /dev/dm-0: 858.9 GB, 858993459200 bytes
Disk /dev/dm-1: 21.4 GB, 21474836480 bytes

Hrm, are either one of these claiming the /dev/sdc device as a component
device? LVM might skip devices that are part of an active dm device.

You might try issuing the command:
pvscan -vv
as root in the booted system. It might provide some information as to why
LVM is not treating /dev/sdc as a PV.
