I run several Beowulf-style compute clusters using CentOS 5. The question has come up of whether having the compute nodes automount needed filesystems is really necessary. Using the automounter complicates other aspects of configuring the cluster, but the cluster software designers believe that the benefits of automounting outweigh the negatives. In a Beowulf-style cluster there is a private usually >= 1Gb/sec ethernet that handles the NFS traffic. There are no routers involved. If the network has problems that would cause NFS to misbehave then the cluster as a whole is probably in trouble. So, you can assume a properly configured and functioning network. So, I'd like to ask the NFS experts on this list whether in a CentOS 5 environment with NFS3 mounts over a functional private network, would using static mounts result in any negatives as compared to automounts. I'm especially interested in overhead on the NFS server.
