Lustre discuss - Jul 2009 - failover software - heartbeat (Lundgren, Andrew)

Andrew,

I was able to get the ipfail to work on my heartbeat 2.1.3 installation.  

Make sure the following line is uncommented in /etc/ha.d/ha.cf:
respawn hacluster /usr/lib64/heartbeat/ipfail

And corresponding with that you must have a ping line with each host
separated by a space.

We have tested this and it works perfectly.  We have 3 ethernet networks to
each OSS and MDS pair.

I have no idea on what pingd is or how it relates to heartbeat.

when an MDS cannot ping the network.  (I tried with 1.0 and 2.0 conf files,
I am currently >using 2.0)  I have a ticket open with the pacemaker project
(no ticket system for the HA stuff...)
>but not resolution.  I am considering writing a script to down the node
when the ping fails, but don''t like the idea.
