[Lustre-discuss] failover software - heartbeat

[Jim Garlick]

We recently put heartbeat v1 in production and along the way
developed some admin scripts including heartbeat resource agent compliant
lustre init scripts, a script to initiate failover/failback and get detailed
status, a powerman stonith interface, and various safeguards to ensure MMP
is on, devices are present and usable, etc. before starting lustre.

If this is of general interest I could post it to a bug for review.
