Hi, a similar or related use case that we tried to solve without success: - a stretch cluster with two disk boxes - a LUN on each disk box guarded by an individual SFEX - a mirror (raid1 or clvm) that survives an outage of one disk box - the mirror should be started if at least one SFEX can be obtained and the other one could not be obtained on a different node
IMHO sdb is not an alternative as this introduces a SPOF.

Use case is iSCSI initiator connection to iSCSI target with two portals. Idea is to have f.e. device manager multipath resource depend on both iSCSI connection resources, but in a "soft" way, so fail of any single iSCSI connection will not cause multipath resource to stop, but fail of both connections will cause it. I should be missing something but I cannot find answer is it possible with current pacemaker. Can someone bring some light?
