After upgrading a system from RedHat 9 to Scientific Linux 4 (a RedHat
EL clone) the system can no longer see my Volume Group! This isn't a
system partition but a "user" one. Also, if it's relevant it was an
'upgrade' not a new install.
pvscan gives me:
/dev/cdrom: open failed: No medium found
PV /dev/hda4 lvm2 [126.39 GB]
Total: 1 [126.39 GB] / in use: 0 [0 ] / in no VG: 1 [126.39 GB]
/dev/hda4 was the only PV in volume group Volume00.
vgcfgrestore -n Volume00 /dev/hda4 gives:
/etc/lvm/backup/hda4: stat failed: No such file or directory
Couldn't read volume group metadata.
Restore failed.
The file /etc/lvmtab.d/Volume00 exists, is several months old and
contains optimistic strings like:
/dev/hda4
Volume00
/dev/Volume00/LogVol00
The directory /etc/lvm/ contains three empty subdirectories:
archive backup lvm.conf
Surely, if I have the Physical Volume I must be able to access the data?
Thanks in advance.
