Any change you are using redundant rings with corosync 1.3? IIRC there
have been protocol changes in corosync 1.4 to support auto-recovery of
rings.

Switch your cluster into maintenance-mode and you can safely stop
pacemaker and corosync without affecting your services on all cluster
nodes. Upgrade corosync and pacemaker on all nodes and start it up ...
if cluster membership and initial resource probing looks good -- disable
maintenance-mode
