commit a9874e1e6928bcc8297dc3e2a19cf70a1e691e99 Author: Hannes Reinecke <hare@suse.de> Date: Mon Feb 23 16:23:31 2009 +0100 Do not start kpartx if no paths are active When multipath runs in a zero-path configuration it's pointless to start kpartx as it can't read anything. Worse, it's keeping the table busy so we can't flush dead maps.
