Hello List Folk ,

I have created a HA environment by using corosync and pacemaker.
Here is my ring status.

============
[~] # corosync-cfgtool -s
Printing ring status.
Local node ID 117918986
RING ID 0
id = 10.77.7.7
status = ring 0 active with no faults
============

Because some reason, I need to change IP address from 10.77.7.7 to another
one in my environment.
Is it possible to inform corosync without restart corosync and pacemaker
processes?
My setting of corosync.conf use "bindnetaddr" not "mcastport".

By the way, my corosync version is

============
[~] # corosync -v
Corosync Cluster Engine, version '1.4.6'

============

Thanks.
