NFS error
HI experts,
Everyday we are receiving lots of alerts (nfs: server yyy02 not responding, timed out/nNODENAME:xxx06.xxx.com) тАжwhile i check i see that i am able to access the nfs server ...this is what i get from /var/log/messages
Jul 12 01:34:01 xxx06 kernel: nfs: server yyy02 not responding, timed out
Jul 12 01:34:01 xxx06 kernel: nfs_statfs: statfs error = 5
Jul 13 01:34:03 xxx06 kernel: nfs: server yyy02 not responding, timed out
Jul 13 01:34:03 xxx06 kernel: nfs_statfs: statfs error = 5
Jul 14 01:34:03 xxx06 kernel: nfs: server yyy02 not responding, timed out
Jul 14 01:34:03 xxx06 kernel: nfs_statfs: statfs error = 5
In fstab the timeout value is 50.
yyy02:/MicroStrategy/Desktop/XSLs/Maintenance /yyy02/Maintenance nfs soft,tcp,intr,timeo=50 0 0
I think for a few sec. the client is not able to communicate with the nfs server so that it is showing error msg. Now if i increase the timeout value will it solve the issue?
xxx06:-Red Hat Enterprise Linux AS release 4 (Nahant Update 9)
2.6.9-89.31.1.ELsmp
yyy02:- windows server
Please let me know your concern.
Regards,
Ani

Re: NFS error
Shalom,
The answer to your question is you can't be sure.
If the source of the problem is a network issue, time timeout may help.
If the source of the problem is the NFS server is flakey, the error message is legimitate and needs to be dealt with at the server.
It all depends on WHY the problem is happening.

Re: NFS error
Hi Ani,
>while i check i see that i am able to access the nfs server
Seems like there is no issue with nfs i believe you can mount to specific folder and to confirm this you may execute command df to mount point.
1.It's slightly issue with internal NW where and you might need to check with your network team why always getting such error.
2. Based on log, it's constantly timeout after 1 hour, you may check internally what is process running on your network / server during that time.
3. If there everything is ok i mean from server/network side, how about if your try to increase value time out > 1 hour ( i don't think this is good practice to implement).
Thanks

You always can restart internet service
#service xinetd (restart/start/stop/status)
Thanks
