I have removed a logical volume from VolGroup00, and then added another
physical volume, from another disk, to that same VolGroup00. After reboot,
I can't use VolGroup00 anymore. No matter what I try to do, it says:

Couldn't find device with uuid 'wx....' and VolGroup00 is unusable.

I removed the physical volume that i last added, but i still get:

For example:
> pvscan
Couldn't find device with uuid '.....'
  PV /dev/hda4      VG  VolGroup00   lvm2  [60.28GB/50.31GB free]
  PV unknown device VG  VolGroup00   lvm2  [37.25GB/37.25GB free]
  Total: 2 [97.53GB] / in use: 2 [97.53GB] / in no VG: 0 [0 ]

I might have modified/removed a partition that was part of VolGroup00, but
I am sure it didn't have any data on it. /dev/hda4 was holding all my
data. Is there any chance that I can get VolGroup00 to work again?

I am using:

LVM version:     2.00.25 (2004-09-29)
Library version: 1.00.19 (2004-07-03)
Driver version:  4.1.2

Thank you,
