I have a FreeBSD 4.11 machine which mounts a volume from a Netapp ONTap. The FreeBSD machine also acts as a Samba PDC. The Samba volumes are in the NFS-mounted volume. There are about a dozen Win2K workstations on the network served by the Samba server. Lately I have noticed that /var/log/messages is full with entries like: ... /kernel: nfs server filer01:/vol/vol0/psa: not responding ... /kernel: nfs server filer01:/vol/vol0/psa: is alive again It seems that the server sometimes is unresponsive for less than a second, many other times it's unresponsive for a number of seconds (as many as 8 seconds). This happens quite frequently, sometimes 60+ times an hour, perhaps not surprising that it doesn't happen or happens rarely when the workstations are not being used. There are also 15-20 "got bad cookie" messages per day. The NFS volume is mounted with rw,-r=3D1024. I have looked at some nfsstat output, but I don't know what if anything should I be looking for there. Is this a FreeBSD or an ONTap problem? What can I do to fix it?
