Just to be clear, heartbeat should _always_ STONITH the peer node before
doing any mount of a Lust
yes it is consistant. I looked up how to induce a panic using sysrq

That will work right, the machine cycles the second takes over and
all is well.
If instead of crashing the node I run 'killall -9 heartbeat'
I can get the panic every time. I even edited the ext
netdump is indeed good for this, but you may have to take two or three
cracks at it ... it doesn't always dump the complete core image, and you
can't really do a whole lot with the incomplete version.

If your servers do IPMI, you probably can configure Serial-over-LAN to get
a console and capture the logs.

I've been using Sun X2200s with Lustre in a similar configuration (IPMI,
STONITH, Linux-HA, FC storage) and haven't had any issues like this
(although I would typically panic the primary node during testing using
Sysrq) ... is the behaviour consistent?

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
