Dear All,
I have a user, running their own Linux (7.1) workstation, who is having
problems NFS-mounting from my ES40. Other clients in the Unit, running
IRIX or Tru64 have had no problems mounting from the same server, but
they probably don't put such a heavy load on the system.
Server:
4-processor ES40, Tru64 UNIX V5.1 (Rev. 732), also running TruCluster
Server V5.1 (Rev. 389), but currently the only machine in the "cluster".
Exported disks are a single 180GB RAID5 volume in an HSZ80, attached by
SCSI (not fibre)
Client:
800MHz PIII running RedHat 7.1
Symptom on Client:
During intensive use, access to the NFS volume freezes. In
/var/log/messages I see things like -
Jun 28 08:32:48 bioinf kernel: nfs_notify_change: attr=1134896, fattr=1146880??
Jun 28 08:37:59 bioinf kernel: nfs: server cluster.mrc-dunn.cam.ac.uk not responding, still trying
Symptom on server:
in /var/adm/messages I see things like -
Jun 27 19:31:50 beta vmunix: NFS server: stale file handle fs(2633,839795) file 433277 gen 32771
Jun 27 19:31:50 beta vmunix: RFS3_WRITE, client address = 193.60.81.170, errno 70
A reboot clears the problem, but it recurs pretty quickly once the user
starts work again. The same code works fine on files NFS mounted from
other makes of server (as far as I can gather - we can't easily test
this as we don't have a non-Tru64 server with enough disk space to test
this). I don't think the individual files are disappearing from under
the user.
Does anyone have any clues as to what's going on, or where I can look
next? I'm new to Tru64 (I'm more familiar with IRIX).
I will, of course, summarize.
Many thanks,
Andrew
