On a two node OCFS2 cluster (version 1.2.5-6 and higher), when the private interconnect interface fails on the first node, the other node panics, hangs or reboots with a message similar to the following:
(18,0): o2quo_make_decision:143 ERROR: fencing this node because it is connected to a
half-quorum of 1 out of 2 nodes which doesn't include the lowers active node 0
(18,0): o2hb_stop_all_regions:1908 ERROR: stopping heartbeat on all active regions.
Kernel panic - not syncing: ocfs2 is very sorry to be fencing this system by panicing.
The above occurs despite there being no apparent issue on the second node.
