We have two nodes that we have the IP address assigned to a bond0 network interface instead of the usual eth0 network interface. We are wondering if there are issues with trying to configure corosync/pacemaker with an IP assigned to a bond0 network interface. We are seeing that corosync/pacemaker will start on both nodes, but it doesn't detect other nodes in the cluster. We do have SELinux and the firewall shut off on both nodes. Any information would be helpful.
We run the cluster stuff on bonding devices (actually on a VLan on top of a bond) and it works well. We use it in a two-node setup in round-robin mode, the nodes are connected back-to-back (i.e. no Switch in between).
If you use bonding over a Switch, check your bonding mode - round-robin just won't work. Try LACP if you have connected each node to a single switch or if your Switches support link aggregation over multiple Devices (the cheaper ones won't). Try "active-backup" with multiple switches.
To check your configuration, use "ping" and check the "icmp_seq" in the replies. If some sequence number is missing, your setup is probably broken.
