What is the best approach when an nfs mount hangs on a client but the server is OK? I have mount options of: rw,bg,soft,intr,rsize=32768,wsize=32768 but whatever it did was not interruptable and would not shut down. There were some: Oct 15 09:08:32 dev-ngf-l-01 kernel: INFO: task gnome-settings-:19169 blocked for more than 120 seconds. Oct 15 09:08:32 dev-ngf-l-01 kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. messages on the console and /var/log/messages. Is this a bug or there a way to avoid it? -- Les Mikesell lesmikesell at gmail.com

Did you also check /var/log/messages on the nfs server side ? I had some NFS troubles with lockd some times ago and it was a firewall problem on the client: Try: - log on the NFS server and check in /var/log/messages which client is responsible for the problem (it could be an other one than your client). - on this client stop iptables (service iptables stop) and check if the problem still exist. In my configs, client iptables fully trust my NFS server.
