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
id =
status = ring 0 active with no faults

Because some reason, I need to change IP address from to another
one in my environment.
Is it possible to inform corosync without restart corosync and pacemaker
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'
