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.
