Booting from the system, this gives:

When I boot from the GParted live-CD:
PV /dev/sdb4 with UUID ecQz2l-Yl5S-s1AR-delt-5zXF-Wnjs-P2y2dH VG system lvm2 [113.03 GB / 0 free] PV /dev/sdc1 with UUID 5P6jGx-ePjX-43Az-wyLL-wuF5-R4Vt-vP9Uff VG system lvm2 [465.76 GB / 0 free] PV /dev/sda with UUID lLWxB7-QmLl-FMXX-KQRW-EDHZ-EHLL-o7DZ1b VG system lvm2 [465.76 GB / 224.54 GB free] Total: 3 [1.02 TB] /in use: 3 [1.02 TB] / in no VG: 0 [0 ]
No error at all. How does the GParted Live-CD do that?
Are the LVM versions different?
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.
If your device is rejected (name
How could I find its name? Is it 'sdc'?
Filtering is based on absolute pathname. So "/dev/sdc", which should be accepted and not rejected your rules.
Disk /dev/sdc: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000
Disk /dev/sdc doesn't contain a valid partition table
That's normal for a whole disk PV.
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. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
