Nightmare file system (NFS)
start here:
/etc/fstab
foohost:/export/data /mnt nfs tcp,rsize=8192,wsize=8192,intr,rw,bg,nosuid,noauto
NFS shares get stale after a while or don't mount at all
This might be caused by the fact that the server really wants to have portnumbers below 1024 for the session. Adding insecure to the exports-file fixes that. Example:
/home somehost(rw,insecure)
