vmunix: NFS server psh-cel-04 not responding still trying

[Jerry L. Sims]

Hello All,

***************
HP-UX B.11.11 U 9000/800/N4000-75
***************

Has anyone experienced the following senario
with NFS. It seems to hang, and then clear itself :

# grep psh-cel-04 /var/adm/syslog/syslog.log

Apr 13 07:57:07 it-hp23 vmunix: NFS server psh-cel-04 not responding still trying
Apr 13 08:47:53 it-hp23 vmunix: NFS server psh-cel-04 ok
Apr 13 08:47:55 it-hp23 vmunix: NFS server psh-cel-04 not responding still trying
Apr 13 08:47:55 it-hp23 vmunix: NFS server psh-cel-04 ok
Apr 13 12:08:46 it-hp23 vmunix: NFS server psh-cel-04 not responding still trying
Apr 13 12:13:52 it-hp23 vmunix: NFS server psh-cel-04 ok
Apr 13 12:13:54 it-hp23 vmunix: NFS server psh-cel-04 not responding still trying
Apr 13 12:13:54 it-hp23 vmunix: NFS server psh-cel-04 ok
Apr 13 14:50:02 it-hp23 vmunix: NFS server psh-cel-04 not responding still trying
Apr 13 14:55:52 it-hp23 vmunix: NFS server psh-cel-04 ok
Apr 13 14:55:54 it-hp23 vmunix: NFS server psh-cel-04 not responding still trying
Apr 13 14:55:54 it-hp23 vmunix: NFS server psh-cel-04 ok
Apr 13 15:00:43 it-hp23 vmunix: NFS server psh-cel-04 not responding still trying
Apr 13 15:13:52 it-hp23 vmunix: NFS server psh-cel-04 ok
Apr 13 15:13:54 it-hp23 vmunix: NFS server psh-cel-04 not responding still trying
Apr 13 15:13:54 it-hp23 vmunix: NFS server psh-cel-04 ok

When th problem happens I execute :
1) ping psh-cel-04 64 3
which works ok
2) # rpcinfo -u psh-cel-04 nfs
program 100003 version 2 ready and waiting
program 100003 version 3 ready and waiting

Not sure why this is happening, or the best way to troubleshoot this problem. I have requested the "psh-cel-04" folks to view their logs for a resaon.

Our "HP N4000" is the client
The "psh-cel-04" is the server

bdf :
psh-cel-04:/cpprodsh_t/porttst /wwwsh

Every time I've seen this sort of thing (at the console on Sun or the logs on HPUX), it's been related to networking issues. The client seems to lose contact with the NFS server temporarily, retries, and reconnects. In one particular case where a number of servers were producing this message, the network was often under high load.

HTH,

This is comman error when NFS server is not available some time and most of the cases its a network issue. Look at the speed of LAN card on both NFS server and NFS client have 100Full Duplex.Also look for the valus NUM_NFSDinto /etc/rc.config.d/nfsconf if that needs to be increased. NFS server could be highly utilized and busy to respond to client.

You may want to look at your network traffic and cpu utilization in glance or glance plus if you have it on your system. I would guess one of systems is getting strained.

Hi,

Maybe this link can help.

The itrc doc id is KBRC00002736.

Hope this helps.

1) Please check is there any autofs mount point..

2) if so check connection protocol using #mount -p command..

3) Check autofs mount point is mounted using tcp or udp

4) if its tcp, edit autofs conf file and make connection protcol to tcp

proto=tcp

5)Retart nfs.client service

Hope this is helpful.
