11.23 NFS and AutoFS

[Pete Randall]

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:

# cd /nfs/farm/prod1
# ll

dr-xr-xr-x 1 root root 1 Feb 13 13:13 WP

# mount |grep common

Fri Feb 13 13:13:07 2009
# ll common
common unreadable
total 0


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 ?

[Pete Randall]

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


Pete

[Victor Fridyev]

Pete,

It seems, nfsstat commanf gives NFS version.

[Pete Randall]

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


Pete

[Pete Randall]

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

[Victor Fridyev]

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

Ping!

Maybe more info would be helpful!

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

Feb 16 12:32:50 t134 LOOKUP REQUEST: Mon Feb 16 12:32:50 2009
Feb 16 12:32:50 t134 name=farm[] map=-hosts opts=nosuid,hard,intr,bg,vers=2 path=/nfs direct=0

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


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"?
