[Lustre-discuss] failover software - heartbeat

[Lundgren, Andrew]

I tried the pingd in v2, and was unable to get it working.  

(I also tried it in pacemaker and ended up opening a ticket that we haven't finished working though yet.)

The fiber ping is only around as a v1 tool as far as I can tell. Since I wasn't able to get normal ping to function, I never even tried the FC stuff.
