NFS server

[Mirjana Vucic]

Hello !

I have a problem with a HP-UX 11. Since it's installation (by someone from HP) allmost every session I start is eventually interrupted by a period of inaction, followed by the message: NFS server not responding still trying
Then the session hangs (sar shows 100% idle) and there's nothing left to do but close the session and start a new one.
Since we don't need the functionality of the NFS server I disabled it using SAM, the situation remained unchanged. I tried to disable the NFS client aswell, but didn't succeed. The message I got said it was unsuccessfull in unmounting the cdrom. I tried killing any process connected to the cdrom but no effect.
Can anyone tell me how I can get rid of the NFS server ?

Any help will be much appreciated.
Kind regards, Mirjana Vucic

in /etc/rc.config.d/nfsconf, set the NFS_SERVER=0 and NFS_CLIENT=0. Then issue

/sbin/init.d/nfs.client stop
/sbin/init.d/nfs.server stop
/sbin/init.d/nfs.core stop


You can use "fuser" to see if any "users/processes" are using the cd rom and can stop it there. For more information, check out the online documentation at

Your problem seems to be because of improper configuration of NFS client only.

First confirm that NFS_CLIENT is set to 1 in /etc/rc.config.d/nfsconf. Kill any user connected to the filesystem which you are getting error, then stop the NFS CLIENT.

#/sbin/init.d/nfs.client stop

(if you set the NFS_CLIENT=0, you can not stop the NFS services)
Then you can change toe NFS_CLIENT=0 to prevent the service to start on next boot.

Did you ever use pfs_mount to mount a rockridge style CD ROM? PFS is a product from Young Minds that allows the mounting of CD ROM format not otherwise supported by HPUX. PFS is very finicky if not patched and if not started/stopped properly. PFS is also built upon NFS. Problems with PFS typically give the NFS Server message that you are seeing. You may want to check to see if you can unmount the CD ROM. If not, check for any processes running such as pfsd, pfs_mountd, pfsd.rpc, or pfs_mountd.rpc. All 4 need to be running to successfully pfs_mount or pfs_umount the CD ROM. Check to see if any of these processes's parent (PPID) is 1 (init). If so, this process is zombied and you will not be able to get rid of it without rebooting. If you turn NFS off like Berlene suggested and then reboot the box, I imagine the NFS/PFS problems will go away.
