You need to make sure the RHEL4/cluster-1.0 binaries are removed from the
nodes and the new RHEL5/cluster-2.0/openais binaries are installed.  If
you're getting this far, it may only be some fencing binaries that are
incorrect, so first just remove fence_manual and fence_ack_manual and make
sure you have the new fence_ack_manual installed (it's now a bash script).
fence_manual no longer exists in RHEL5/cluster-2.0 code since
fence_ack_manual talks directly with fenced.
