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.
