Hi,
We're setting up fairly large Lustre 2.1.2 filesystems, each with 18
nodes and 159 resources all in one Corosync/Pacemaker cluster as
suggested by our vendor. We're getting mixed messages on how large of a
Corosync/Pacemaker cluster will work well between our vendor an others.

Shawn,
In my opinion you shouldn't be running corosync on any more than two
machines. They should be configured in self contained pairs (mds pair,
oss pairs). Anything beyond that would be chaos to manage, even if it
worked. Don't forget the stonith portion. Not every block storage
