There are primary/primary setups possible with drbd and gfs if you need both nodes to be exported at the same time - but that's not needed nor recommended in a failover situation.

Why would it not be recommended for a failover situation?

Because it would be shooting cannons at birds in this particular case. If you need to expose both nodes "to the public" all the time, you probably also run the software on both nodes - which would be more of a cluster than a failover setup >:)

But, a cluster in itself is fail over :) If either node is dead, the cluster is still up
