duplicate volume group names

hi,

------------

# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found active volume group "vg0"
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume
group

# vgchange -a y
vgchange -- volume group "vg0" already active

# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/ide/host2/bus0/target0/lun0/part3" of VG
"vg0" [55.71 GB / 14.14 GB free]
pvscan -- inactive PV "/dev/ide/host2/bus0/target1/lun0/part3" of VG
"vg0" [37.07 GB / 280 MB free]
pvscan -- total: 2 [92.79 GB] / in use: 2 [92.79 GB] / in no VG: 0 [0]

----------

and the question:
is it possible to get data from the second hdd if it has the same volume name?
the second hardrive comes from a different computer and has nothing to do with the 'vg0' of the first (system) hdd

do i need to change the name of the volume group name of the system disk first?

regards

ps. plz respond to private email as i am not subscribed to the list

Michal,

detach the 2nd HDD, vgrename "vg0" to something, reattach the 2nd HDD, run "vgscan;vgchange -ay" and you should be able to access both. Keep necessary /etc/fstab changes in mind doing so.

Regular procedure for such VG moves from one computer to another is "vgchange -an VG ; vgexport VG" on the 1st one, move PVs to the 2nd computer and run "vgimport VG PVPath [PVPath...]" there.
