We've got a Sun V880 running Solaris 9. 2 days ago it started exhibiting
NFS trouble. We have some working and data directories mounted from
a Solaris 8 NFS server and home directories and other working areas
mounted from an Netapp Filer F820. The symptoms are the NFS servers appear
to the V880 to stop responding, yet they're fine from all the other
development machines we have accessing them, and there are no errors on
the NFS servers themeselves. All the machines are connected by Fibre
Optic Gig networking.
A CVS checkout on one NFS mount causes that mountpoint, and all the others,
to stop responding. It seems like the core NFS client stuff in Solaris 9
throws a wobbler somewhere when we start using NFS heavily. The strange
thing is, this has been working fine for months, and just in the past
few days, this one machine has had nonstop NFS trouble.
The first thing I tried, naturally, was rebooting into single user mode
and installing the latest patch cluster for Solaris 9. This hasn't made
any difference. Killing off the CVS command and waiting for a while for
things to possibly recover doesn't work, all the NFS mountpoints remain
nonfunctional - the machine has to be rebooted to get NFS working again.
I'm going to test to see if I can trigger the symptom with just NFS IO. I've
tried to trigger the same symptom on our other Solaris 8 and 9 boxes
but they continue working just fine.
Any ideas what's going on?
