When configuring encrypted on-pvc clusters we now set the cluster fsid in the LUKS header. If needed we can then determine if the encrypted block is part of our cluster or not. We also attach the pvc_name in case it might become useful. Closes: https://github.com/rook/rook/issues/7991 Signed-off-by: Sébastien Han <seb@redhat.com>
