So I am trying to set up a redundant NFS share in a cloud environment(all links internal, half gig links), and I am looking into using heartbeat for failover, but all the guides seem to be about combining DRBD and heartbeat to create a robust environment. If need be I can do that, but since my content is almost completely static, I would like to avoid the extra overhead and complexity of DRBD if possible, but still be able to fail over if one of the NFS servers fails. Is it possible to use heartbeat with NFS to achieve high-availability without using DRBD to copy the blocks? I am not married to NFSv4, so if NFSv3 over UDP is necessary, that won't be a problem(only a very small number of clients will be connecting to the share)

Any comments are appreciated.
