Hi, I have removed a logical volume from VolGroup00, and then added another physical volume, from another disk, to that same VolGroup00. After reboot, I can't use VolGroup00 anymore. No matter what I try to do, it says: Couldn't find device with uuid 'wx....' and VolGroup00 is unusable. I removed the physical volume that i last added, but i still get: For example: > pvscan Couldn't find device with uuid '.....' PV /dev/hda4 VG VolGroup00 lvm2 [60.28GB/50.31GB free] PV unknown device VG VolGroup00 lvm2 [37.25GB/37.25GB free] Total: 2 [97.53GB] / in use: 2 [97.53GB] / in no VG: 0 [0 ] I might have modified/removed a partition that was part of VolGroup00, but I am sure it didn't have any data on it. /dev/hda4 was holding all my data. Is there any chance that I can get VolGroup00 to work again? I am using: LVM version: 2.00.25 (2004-09-29) Library version: 1.00.19 (2004-07-03) Driver version: 4.1.2 Thank you, George _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
