Hi,
I have set up a rather simple RSF-1 project, where two RSF-1 nodes
connect to two storage heads via iSCSI. I have deployed one network and
two disc heatbeats and I was trying all sorts of possible failures, when
I noted that one node would panic, if I offlined an iSCSI target on one
storage node and thus shutting down one side of a zpool mirror
completely. Issueing a zpool status would't return and after a while the
host got nuked.
I then onlined the target again and waited until the node returned and
than removed the local iSCSI initiator on the RSF-1 node instead, which
resulted in a degraded, but functional zpool and this time, the node
didn't get nuked.
What is the difference between these two approaches and can I setup my
systems such as that offlining a target doesn't lead to this behaviour?
I'd imagine, that a target failure might as well occur as any other
sofware fault.
Thanks,
Stephan
