A follow up to this, I downloaded uuid_fixer to see if it would help, here's what I tried: [root@ipso uuid_fixer]# ./uuid_fixer /dev/hda6 Error: number of PVs passed in does not match number of PVs in /dev/hda6's VG 1 PVs were passed in and 2 were expected. [root@ipso uuid_fixer]# ./uuid_fixer /dev/hda6 /dev/hdb6 Error: number of PVs passed in does not match number of PVs in /dev/hdb6's VG 2 PVs were passed in and 3 were expected. Hrmm, so it must be looking for the partition I deleted on /dev/hdc. :( I re-created the partition just to see: [root@ipso uuid_fixer]# ./uuid_fixer /dev/hda6 /dev/hdb6 /dev/hdc1 Error: number of PVs passed in does not match number of PVs in /dev/hda6's VG 3 PVs were passed in and 2 were expected. Figures. I guess I don't have a backup of the vgcfg when /dev/hda6 was all alone in the VG "quantum". Thats the last time it was working correctly. :( Quoting IpSo <ipso@snappymail.ca>: > I was trying to extend my LVM partition to another disk, but being late and > my > head not screwed on straight, things went terribly wrong. > > I was using diskdrake (from Mandrake) and what I did was create a LVM > partition > /dev/hdb6 and added it to my "quantum" VG which contained a single partition > of > /dev/hda6.
