[Linux-cluster] Two node NFS cluster serving multiple networks

[Alex Kompel]

You will still need some way to tell the system through which
interface you want to route outgoing packets for each target.
You can achieve the same with greater ease by splitting the network in
 2 subnets and assigning each to a single interface.
It all depends on the problem you are trying to solve. If you want
redundancy - use active-passive bonding, you want throughput - use
active-active bonding (if your switch supports link aggregation), if
you want security and isolation - use separate subnets.

RG Manager will add the floating interfaces to the "correct" interface, that is, if your floating ip is 1.2.3.4 and you have a interface with the IP address 1.2.3.3 he will add the IP to that interface.
