How to disable all system's NFS processes?

[MA Qiang]

I have changed
NFS_CLIENT=0
NFS_SERVER=0
in /etc/rc.config.d/nfsconf. And restarted the server. But I found 'nfskd' and 'nfsktcpd' still in my system.
How to disable them?

Thank you!

nfsktcpd is kernel thread (PPID 0) responsible for NFS/TCP traffic and nfskd is supposed to be its NFS/UDP equivalent, but it's currently not in use on HP-UX.

Not 100% sure, but I think nfskd and nfsktcpd would disappear if you disabled NFS/9000 kernel subsystem. You can do this with SAM (SAM -> Kernel Configuration -> Subsystems -> Highlight NFS/9000 -> Actions -> Remove Subsystem from Kernel -> Process New Kernel -> reboot).

If I was you, I wouldn't bother. For the purpose of disabling NFS on the system, what you did is sufficient.

I want to try to remove the subsystem from kernel. But how to recover it if I need it later?

Thank you!

If you want it back, you can re-add it through the same SAM submenu as indicated in the previous post. You will have to rebuild kernel and reboot again.

But as I said earlier you shouldn't need to do this. If all you want is to disable NFS, setting NFS_CLIENT and NFS_SERVER to 0 in /etc/rc.config.d/nfsconf is sufficient.

We have installed EMC Legato DXUL on the HP-UX server. The DXUL NFS server's dual mode is not work correctly, only DXUL-SM filesystem can be NFS mounted, native UNIX filesystem can not be NFS mounted. We will try it by disabled all the system's NFS functions.

Thank you!

Hi,
Normally i would prefer this way to stop NFS.


1. Ensure if any exported file system is not in use.

2. Stop NFS client daemon
# /sbin/init.d/nfs.server stop

3. Stop NFS server daemon
# /sbin/init.d/nfs.server stop

4. Stop NFS core daemon
# /sbin/init.d/nfs.core stop
This will stop NFS entirely.
Then if you disable it permanently and should start after rebot then you need to set following two parameters in /etc/rc.config.d/nfsconf.
NFS_CLIENT=0,NFS_SERVER=0

This should work.

sorry one typo there:

Read:

2. Stop NFS client daemon
# /sbin/init.d/nfs.server stop

as

2. Stop NFS client daemon
# /sbin/init.d/nfs.client stop
