It actually seems to work pretty well these days, our general config is: 1) No automounter 2) Hard mounts (so jobs just hang if they loose contact) 3) NFS over TCP (NFS over UDP is sooo 1990's :-)) 4) Jumbo frames (9000 byte MTUs) on the NFS network 5) NFS file server has hardwired fsid's to prevent stale file handles on a reboot 6) Debian, not RHEL on the server 7) XFS for /home on the server cheers, Chris -- Christopher Samuel - (03) 9925 4751 - Systems Manager The Victorian Partnership for Advanced Computing P.O.
