This is an alternative to 10.interface and is installed as disabled by default. It should only be used with DisableIPFailover=yes and when IP failover is being handled externally. In this mode CTDB can be informed of public IP address movements using "ctdb moveip". During the "startup" event, this eventscript currently finds any public IP addresses configured in $CTDB_PUBLIC_ADDRESSES and tells CTDB which node they are on using "ctdb moveip". This allows CTDB to send ARPs and tickle-ACKs. Pair-programmed-with: Amitay Isaacs <amitay@gmail.com> Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com>
