Re: [linux-lvm] Lost a full volume group!

Rodrigo,

somthing must have corrupted your LVM metadata on /dev/hda4.
Can't be LVM because there's no mention of any changes to the PV in /dev/hda4.

Don't try to change your VGs before we figured out what went wrong!

Did you run vgck and what did it tell you about your VGs ?
Does pvscan still show _all_ you PVs ?
