Not sure, but if the reason the disk was moved was because a cpu went out, i'm assuming the old root fs is also on that disk - hoping so anyway ;) If so, the old root fs can be mounted and /etc/lvm/archive can be checked for a valid copy of the metadata. (Assuming root wasn't on lvm...) As to why vgcreate didn't recognize the old VG...that's very odd - not sure what went wrong there... -- AJ Lewis Voice: 612-638-0500 Red Hat E-Mail: alewis@redhat.com One Main Street SE, Suite 209 Minneapolis, MN 55414 Current GPG fingerprint = D9F8 EDCE 4242 855F A03D 9B63 F50C 54A8 578C 8715 Grab the key at: http://people.redhat.com/alewis/gpg.html or one of the many keyservers out there...
