I have two machines I am setting up as my first mds failover pair.
The two sun x4100's are connected to a FC disk array. I have set up
heartbeat with IPMI for STONITH.
Problem is when I run a test on the host that currently has the mds/
mgs mounted 'killall -9 heartbeat' I see the IPMI shutdown and when
the second 4100 tries to mount the filesystem it does a kernel panic.
Has anyone else seen this behavior? Is there something I am running
into? If I do a 'hb_takelover' or shutdown heartbeat cleanly all is
well. Only if I simulate heartbeat failing does this happen. Note I
have not tired yanking power yet, but I want to simulate a MDS in a
semi dead state and ran into this.
