Are you sure you are running 6.5.3 ? We had a very similar issue when we upgraded to 6.5.2 last year. The BUG was identified as 139351 and fixed in 6.5.2P6 (http://now.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=139351) Hope it hasn't re-appeared in 6.5.3 ! -G

Hi,
We have three Debian systems (two with 2.6.x Kernel and one with 2.4) using a NetApp 720 (6.5.3) as an NFS server.
On two occasions in the last two weeks, when one of the Linux hosts tried to mount a file system from the netapp we got the error: Host nono not responding. (nono being the filer name)
From that moment, no action could be preformed from any of the Linux hosts on the netapp. We see not errors in the log files of either the Linux nor the netapp. Other functions (CIFS, NIS and DNS lookups) continue with not issues.
Attempting to stop and start the NFS service on the netapp did not have any effect, neither did rebooting the clients.
The only workaround was rebooting the filer, after which all NFS operations resumed without a problem.
I have started a trace on NFS, but did not get the same hangup yet.
Did anyone encounter a similar situation, or alternatively can advise on where and what to check?
Thanks
Gil
