Do u mean rescue env like booting with the rescue cd?

I tried to do like u said but when i disconnect the drive, some other
device take /dev/sdc from the failed drive but LVM complains that UID
is missing and when i check /etc/backup/VG i can see the missing UID
and that is the drive that have failed /dev/sdc

Now i'm afraird to remove the /dev/sdc from the volume group beacuse
some other drive took over /dev/sdc.

Can u please provide some useful commands that i can begin with?

Kind regards
