Hi list,
is it possible to import a duplicate VG name from a read-only device?
I know about vgrename, but it needs to update metadata - which is not
possible for read-only device.
I tried to un-manage the host native read/write VG, deleting it from
system.devices, but lvchange -ay shown an error about not being able to
create the /dev/VG/LV symlink (and a "device busy" issue, probably
related to the already-existing symlink). I also tried to activate the
specific LV via lvchange -S lv_uuid, but it shown the same error as
above.
In this specific case I put the device in r/w mode and solved the issue
with a plain vgrename. But what if I could not enable writes on the
device? Is the only solution to mount it on a machine without the same
VG name (ie: on a live USB), or can a VG/LV be enabled specifying a
different path for the symlink?
Thanks.
