11.23 NFS and AutoFS

Pete Randall — Fri, 13 Feb 2009 18:22:38 GMT

My new 11.23 environment seems to be having some NFS difficulties. It's behaving just fine with other HP-UX environments with automounts happening in both directions (from the 11.23 box to the others and from the others to the 11.23 box).

However, our Novell file server at the heart of our LAN doesn't seem to want to play nicely. It appears that the 11.23 box attempts to automount as it should but we can't read anything past the exported LAN directory:

On my other 11.11 machines, this works just fine. What am I missing?

Another question: how do I check which version of NFS I have?

What about nfsstat ?

Sorry, Victor, I'm not following. What do you mean, "what about nfsstat"?

Pete,

It seems, nfsstat commanf gives NFS version.

Re: 11.23 NFS and AutoFS

Pete Randall — Fri, 13 Feb 2009 18:46:39 GMT

Well, yes, it does seem to indicate that I have either Version 2 or Version 3.

Re: 11.23 NFS and AutoFS

Pete Randall — Fri, 13 Feb 2009 18:51:05 GMT

OK, I see - it's telling me it will support both v2 and v3. Presumably that's as a client and as a server, I would expect it to be v3?

Pete

Re: 11.23 NFS and AutoFS

Victor Fridyev — Fri, 13 Feb 2009 18:55:13 GMT

V3 works for sure.
BTW, 11.23 has some problems with autofs, e.g. I have not succeeded to change AUTOMASTER name, i.e. I edited /etc/auto.master, but the comp read /etc/auto_master, even the variable was changed in the configuration

Good Luck

Maybe more info would be helpful!

Here's the AutoFS trace entries of the mount attempt:

Feb 16 12:32:50 t1 Port match
Feb 16 12:32:50 t1 MOUNT REPLY : status=13, AUTOFS_DONE

And the exported directories, as seen from the NFS client:

# showmount -e farm
export list for farm:
/image1/vol1 (everyone)
/prod1/BTID/download (everyone)
/prod1/common (everyone)

So, why is "access denied"?

Shalom,

11.11 works with this Novell server.
11.23 does not.

I would check the patch database against the error message and the keyword Novell. Read the notes see if there is something that applies.

If in a hurry, put together a large nfs patch set, install it and hope the shotgun gets the problem.

I used to work with victor and if you published the configuration files he or I might be able to spot something.

No patch hits with any keywords other than just "nfs", so I applied all the latest nfs and autofs patches. Still no joy.

Dennis Handly — Tue, 17 Feb 2009 18:10:35 GMT

Have you bypassed the automounter and tried hard mounting common? Do it somewhere else to check, /var/tmp/common/.

Re: 11.23 NFS and AutoFS

Dave Olker — Tue, 17 Feb 2009 18:17:35 GMT

Hi Pete,

Let's take a look at the working and failing system to see what they're doing.

On the 11.11 NFS client, issue the commands:

# nfsstat -m
# rpcinfo -p

I'd also like to see the AutoFS maps used to mount the filesystem from the Novell server.

Then on the 11.23 NFS client, issue the command:

# nfsstat -m

and collect the AutoFS maps used by the 11.23 system to mount the Novell filesystem (unless they are the same maps being shared via NIS or something).

Regards,

Dave

On the 11.23 client:

Both AutoFS maps used to have "bg" specified until an hour or so ago when I read that it wasn't allowed for an automounted directory. Taking it out didn't help.

Re: 11.23 NFS and AutoFS

Dave Olker — Tue, 17 Feb 2009 18:33:06 GMT

I guess I should have made it clear that before issuing the "nfsstat -m" commands you'd need to actually mount the filesystems so they'd show up in the output. :)

So, on both systems please force AutoFS to mount the filesystem first then issue the nfsstat -m command on both systems.

Also, can you tell me if the 11.11 system is using the original automounter, the original (ONC 1.2) AutoFS, or the Enhanced AutoFS?

Dave

Re: 11.23 NFS and AutoFS

Pete Randall — Tue, 17 Feb 2009 18:37:46 GMT

The 11.11 system is using the original automounter and I attempted to mount before issuing the nfsstat command.

Re: 11.23 NFS and AutoFS

Dave Olker — Tue, 17 Feb 2009 20:29:04 GMT

On the working 11.11 system, try this:

# cd /nfs/farm/prod1/common
# nfsstat -m

Hopefully that will show the NFS mount.

Looking at the AutoFS log you provided:

AUTOFS_ACTION
Feb 16 12:32:50 t1 MOUNT REQUEST: Mon Feb 16 12:32:50 2009
Feb 16 12:32:50 t1 name=farm[/prod1/common] map=-hosts opts=nosuid,hard,intr,bg,vers=2 path=/n
fs/farm/prod1/common direct=1
Feb 16 12:32:50 t1 Port numbers are 666, 666
Feb 16 12:32:50 t1 Port match
Feb 16 12:32:50 t1 MOUNT REPLY : status=13, AUTOFS_DONE

The NFS server is denying the last mount request with "status=13". That too would explain why the overall NFS mount is failing.

As Dennis suggested earlier, try doing a manual NFS mount on the 11.23 system just to take AutoFS out of the picture for the moment:

11.23> mkdir /test1
11.23> mount farm:/prod1/common /test1

If that works, issue the "nfsstat -m" command so I can see what got mounted.

Re: 11.23 NFS and AutoFS

Pete Randall — Wed, 18 Feb 2009 11:27:55 GMT

Dennis & Dave,

11.11# cd /nfs/farm/prod1/common
11.11# nfsstat -m
11.11#

11.23# mkdir /test1
11.23# mount farm:/prod1/common /test1
No such file or directory

The only time I can get anything out of the nfsstat command is on the 11.23 system when I cause one of the 11.11 systems to get automounted.
