It is a ZFS based illumos system. I don't think SBD is an option. Is there a reliable ZFS based stonith?

The situation is a dual node server with shared storage controller: both nodes see the same disks concurrently. Here we must be sure that the two nodes are not going to import/mount the same zpool at the same time, or we will encounter data corruption: ssh based "stonith" cannot guarantee it. node 1 will be perferred for pool 1, node 2 for pool 2, only in case one of the node goes down or is taken offline the resources should be first free by the leaving node and taken by the other node. Would you suggest one of the available stonith in this case? IPMI, managed PDU, SBD ... In practice, the only stonith method that works in case of complete node outage including any power supply is SBD. _______________________________________________Manage your subscription:https://lists.clusterlabs.org/mailman/listinfo/usersClusterLabs home: https://www.clusterlabs.org/
