[Lustre-discuss] failover software - heartbeat

[Jim Garlick]

Hi,

OK I have posted it to https://bugzilla.lustre.org/show_bug.cgi?id=20165

  20165: scripts for heartbeat v1 integration

I added example config files from our test cluster.  Probably best to
redirect questions/comments/criticisms to the bug and I'll respond there.

Jim
