Helu,

I am in 
dire need of some help.I recently removed an old disk from 
my PV and added a new one  
 in place of the old one.
e.g.

pvmove garage /dev/hdj1 /dev/hde1 
(hde1 being the new drive)

The physical extents moved over to 
the new drive and everything was looking good until
I made a pretty big mistake, I 
figured I’d need to export the group ‘garage’ and import it.
Wrong! Now when I go and try to 
import my group it freaks stating:

# vgimport garage /dev/hde1 /dev/hdg1 /dev/hdf1
vgimport -- ERROR: wrong number of 
physical volumes to import volume group "garage"

I can’t do 
a vgcfgrestore either, because it is currently exported and I am not sure if 
that would
fix anything anyways… Here is some more 
information:

# pvscan
pvscan -- reading all physical 
volumes (this may take a while...)
pvscan -- inactive PV 
"/dev/hdg1"  is in EXPORTED VG "garage" [74.55 GB / 0 
free]
pvscan -- inactive PV 
"/dev/hde1"  is in EXPORTED VG "garage" [76.33 GB / 0 
free]
pvscan -- inactive PV 
"/dev/hdf1"  is in EXPORTED VG "garage" [74.52 GB / 60.21 GB 
free]
pvscan -- total: 3 [225.42 GB] / in 
use: 3 [225.42 GB] / in no VG: 0 [0]

vgscan –d output can be found at: http://www.planetgarage.net/vgscan.txt
