I created a couple luns (without second path) using iet, and then using the iscsi initiator to access them. But it seems like no I/O is possible through dm-mpath for this simple setup as the kpartx processes spawned by udev already hang. Is dm-mpath (default config, no multipath.conf) support to work for a single path setup, or is this expected behavior? Does anyone have a good default iet or maybe lio config for dm-mpath testing?
