'nfs.server stop' does not work on Itanium 11.23

Bob_Vance — Thu, 22 Jun 2006 08:55:40 GMT

HPUX 11.23
rx1600 itanium

*********************************
NFS server starts up fine at boot.
*********************************

It also will start if I
. disable NFS server (NFS_SERVER=0 in nfsconf)
. reboot
. re-enable NFS (NFS_SERVER=1 in nfsconf)
. 'nfs.server start'

I get processes like this:

daytona2 ## psg nfs
... root 9 0 0 08:48:52 ? 0:00 nfsktcpd
... root 1708 1702 0 08:51:15 ? 0:00 /usr/sbin/nfsd 16
... root 1707 1701 0 08:51:15 ? 0:00 /usr/sbin/nfsd 16
... root 1702 1701 0 08:51:15 ? 0:00 /usr/sbin/nfsd 16
... root 1700 1 0 08:51:15 ? 0:00 /usr/sbin/nfsd 16

... root 1720 1702 0 08:51:16 ? 0:00 /usr/sbin/nfsd 16

And it works -- clients can mount stuff.

**********
However,
**********
when I try a
... /sbin/init.d/nfs.server stop
not all the 'nfsd' processes get killed.

Furthermore, I cannot kill the remaining ones, even with a 'kill -9 ...'

No clients have mounted anything, so it is clean -- just after a reboot.

At this point, even if I manually start
'rcp.mountd'
clients still cannot mount anything.

A RESTART doesn't help either:

daytona2 ## /init.d/nfs.server start
.. starting NFS SERVER networking
..... starting up the rpcbind daemon
........ rpcbind already started, using pid: 796
..... Reading in /etc/exports
..... starting up the mount daemon
........ rpc.mountd already started, using pid: 14631
..... starting up the NFS daemons
........ nfsd(s) already started, using pid(s): 1707 1702 1701 1712 ...
..... starting up the Status Monitor daemon
........ rpc.statd already started, using pid: 842
..... starting up the Lock Manager daemon
........ rpc.lockd already started, using pid: 848

clients still cannot mount anything.

******************************
I have the latest NFS patches:
******************************

daytona2 ## grep -i nfs /tmp/swlistpr
... PHCO_32523 1.0 quota(1) on an NFS client;uid enhancement
... PHKL_32713 1.0 nfs client hang; cache FS umount
... PHNE_33098 1.0 Core NFS cumulative patch
... PHNE_33655 1.0 NFS cumulative patch

Actually, PHNE_33655 has been superseded by PHNE_33982,
but PHNE_33982 does not help, either.

This procedure works perfectly fine on 11.11, of course,
but I do not have an 11.23 PA-RISC system to check.

Has anyone else seen this on Itanium 11.23??
Or do they have one where it works fine ?

Before attempting to stop the server, you should stop the client first.

Correct order to recycle NFS is:

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

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

Thanks, Geoff

But I only want to stop the server.
You can certainly stop the server without stopping the client -- there is logic in the scripts to handle this and it seems to work fine on 11.11.

Further, the problem (11.23 NFS server unable to be stopped) exists even when client has never been started; e.g., NFS server-only system.

Anyway, stopping client first made no difference to the problem on Itanium 11.23.

Okay - I'll try it - I have 1 Itanium box running 11.23:

killing nfsd
killing rpc.mountd

root@sha1 [ / ]
# ps -ef |grep nfs

And startup worked:

# /sbin/init.d/nfs.server start
starting NFS SERVER networking

starting up the rpcbind daemon
rpcbind already started, using pid: 1313
starting up the mount daemon
/usr/sbin/rpc.mountd

/usr/sbin/nfsd 16
starting up the Status Monitor daemon
rpc.statd already started, using pid: 1434
starting up the Lock Manager daemon

Here's the version I'm running:

Here's my patches:

Bob_Vance — Thu, 22 Jun 2006 17:46:39 GMT

Thanks, Geoff.

That proves that it is supposed to work :>)

Now, the question is why not on my systems :[

The only patch difference I see here is that I have tried 2 later NFS cumulative patches than your PHNE_32055 (PHNE_33655 and PHNE_33982).

However, my OE is also a little earlier (sep04)

HPUX11i-OE-MC B.11.23.0409 HP-UX Mission Critical Operating Environment Component

I guess I'm just stuck.

Yeah - I loaded the Dec05 version in January. So far - it's been very stable. This is on my workstation - I usually run new releases on it for 6 months prior to moving to any test servers, then I roll out to production.

As far as your issue - I would put a cal into HP - as what you want to do does work - just not on that server for some reason.

Yesterday, I updated the system with all the latest patches.

They included a new NFS cum patch.
This seems to have fixed the problem:

old patch
... PHNE_33982 1.0 NFS cumulative patch

new patch
... PHNE_35118 1.0 NFS cumulative patch
