Still no luck though.

Well, that's an LVM volume. You have to run first pvscan (or lvm pvscan) and see what physical volumes are created (let's hope you'll find /dev/hdc2 there) and what volume groups are available on that physical volume. After that you have to run lvscan (or lvm lvscan) and see what logical volumes are available (assuming that the current running kernel supports the LVM version of that volume).

    Running pvscan rull generate the and output alike with the following:

pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/hdc2" of VG "Volume00" [33.59 GB / 0 free]
pvscan -- total: 1 [33.60 GB] / in use: 1 [33.60 GB] / in no VG: 0 [0]


Thanks Tarhon. Pvscan doesn't show /dev/hdc2 at all. Does pvscan only work on mounted drives?

[root moe ~]# pvscan
  PV /dev/hda2   VG VolGroup00   lvm2 [74.41 GB / 32.00 MB free]
  Total: 1 [74.41 GB] / in use: 1 [74.41 GB] / in no VG: 0 [0   ]

[root moe ~]# lvscan
  ACTIVE            '/dev/VolGroup00/LogVol00' [72.44 GB] inherit
  ACTIVE            '/dev/VolGroup00/LogVol01' [1.94 GB] inherit

Thanks,
Mike
