[Linux-cluster] Can machine running RHEL 5.3 be a cluster member of a cluster with RHEL 5.2 OSes.

[Corey Kovacs]

Indeed it will. the change in openais means that cman from 5.2 just
can't talk to 5.3.

I have a cluster running 5.3 64bit that I am about to put into
production and it's running like bandit.

Glad I could help.

Also, the info was already posted so I won't take credit for it.
