[linux-lvm] flascopy lvm

[Heinz J . Mauelshagen]

Cynthia,

with any kind of block level copies you get an identical copy
of your existing volume group(s), therefore doubling the VG(s) if
attached to the same system.

A way to get the copy online is to temprarily rename the source VG using
vgrename (any mounted/opened logical volumes will stay in place unless you
reboot), attach the LUNs with the copy, run vgscan and activate the copy,
use vgrename to give the copy a new name and rename the source VG back.

Regards,
Heinz    -- The LVM Guy --
