Wow, you block icmp internally?  This would incur a timeout for every host
listed in your replicated server entry, and with Ian's patch, it would
incur a timeout for non-replicated servers, as well.  In fact, for the
non-replicated server case, I think it would give a false negative, failing
the mount even though the server is up.

Is this really how you have things configured? NFS clients can't ping
their servers?



In a large environment it wouldn't be uncommon to have NFS mounts that span across a WAN. Using NFS over TCP seems to make the most sense in that situation.


As packets traverse the WAN, there may be routers that block icmp. This is the type of situation where replicated server would make the most sense - find the fastest server.
