Do a dmesg on you NFS-server and see if you are seeing any hdd issues on 
the server.

[ilugd] NFS client - Urgent

2009-04-08 Thread Yashpal Nagar
Hi All

We are running  NFS clients on Redhat and SUSE linux distros with the
following options.

NFSSERVER:/home/idpssupp/REPORTS/mnt/amosoutput nfs nfsvers=3,bg,intr 0
0

for some time quite happily, recently we have encountered the messages on
NFS clients

Apr  7 07:11:51 NFSCLIENT kernel: nfs: server NFSSERVER OK
Apr  7 07:11:51 NFSCLIENT kernel: nfs_statfs: statfs error = 116
Apr  7 07:21:06 NFSCLIENT kernel: nfs_statfs: statfs error = 116

I have tried using...
NFSSERVER:/home/idpssupp/REPORTS/mnt/amosoutput nfs
nfsvers=3,hard,intr,noac 0 0

and ran

mount -o remount /mnt/amosoutput

but still we get the following...

NFSCLIENT:~ # ls -l /mnt/amosoutput
/bin/ls: /mnt/amosoutput: Stale NFS file handle

The above problem appears intermittently and would disappear if i just
umount and mount the file systems manually.


A call is already raised with Redhat but still no response.

We have mix of NFS clients on RHEL ES 4, SLES 9 and NFS server is AIX 5.2
ML10. Any help is much appreciated.


Regards,
Yash

 You are losing connection to the NFS server. Is the connection stable? Have
 you tried mounting hard,nointr? To clear the stale file handle warnings you
 can remove the nfs filesystem from the /etc/mtab and remount.


You need to recheck all hardware cables and switches.If it was working
okay then you should not loose it. Also check disk transfer rates with
hdparm. Check if memory is being reported correctly with free

1. Check Network connection between NFS server and clients for  TX/RX
errors.
2. Are you using automount to mount NFS if yes , check timeout period
3. Check by changing the NFS parameter sync to async,
4.  Increase the number of running nfsd by modify /etc/sysconfig/nfs
RPCNFSDCOUNT=16  (default is 8)
Then restart nfsd.
5. check dmesg for NFS error

Removed the entry from /etc/mtab

and ran the
mount -o remount /mnt/amosoutput

I really doubt if the above works, it simply come to next prompt

I still see

NFSCLIENT:~ # ls -l /mnt/amosoutput
/bin/ls: /mnt/amosoutput: Stale NFS file handle

the entry for the /mnt/amosoutput didn't reappear in /etc/mtab after I ran
the mount with remount option. mount though shows the new options picked
with for the shares in question.

nointr -- I can try with, but why even after remount, it doesn't pick
options.

Both (NFS server, NFS client) servers are 1000mbps duplex full.

hdparm on NFS client you mean? NFSclient server is 15k RPM disks (2 T)
storage, RAID 1  RAID5 with two raid array controllers.

Have you checked the network connectivity? Use ping/ping -f and see if there are
any dropped packets. Maybe the network card is giving trouble.
