Cluster randomly started broadcasting
We recently patched our cluster software to version cman-2.0.115-85.
The cman software is broadcasting on our backup network. In our cluster.conf file our backup ip is not listed anywhere.
When I bring down backup interface cluster failsover to other node and will not let me bring service back. When I close the port with IP tables that it is communicating on it causes cluster to fail on that node. The broadcast follows the primary node.
The problem only exists on one 2 node cluster. The only difference from the other clusters is the patch.
Why would it randomly start broadcasting on a network that isn't even listed in our cluster.conf file? Also what could be causing this? And finally how can I disable this broadcast if possible?
When I look at traffic on the backup network it looks like broadcastip.netsupport is present on all three clusters all running on backup network.
