Host 1 has some directories from Host 2 and vice versa. Both are running 3.2-RELEASE (and previously ran 3.1 and 3.0) and from time to time, one server will complain about the other not responding. Jun 1 07:54:39 russian-caravan /kernel: nfs server \ earl-grey.cloud9.net:/home/users: not responding The other machine continues to be up and the mount point still works. Once in a while nfs will say that the host is alive again, but usually there will be several of the above error messages in a row with no mention of the condition fixing itself. The machines have Intel EtherExpress Pro 100B cards (or Asus P2B boards with the cards built-in) and are attached to each other on a Cisco Catalyst 2900XL 10/100 switch. They speak 100/full duplex to the switch. Currently -s,-i,-T,rw is being used to mount the directories, but the TCP transport has not really cleared up or helped the problem. Other NFS issues between 2.2.7 and 3.2 have been cleared up, but this is the most annoying (and only) problem that we've seen persist. I'm tempted to toss the Cisco and try a different switch or just a dumb hub, but I'm not entirely convinced it is the switch. Is there extra debugging that NFS can use when it runs into the condition described above? Like perhaps what exactly makes it think the other host is not responding? -- Scott M.
