NFS linux Server and 10.2 client

[Mr LAMARTA]

Hi,
I've an NFS server MDK7.2 on which i've move my homedirs, and 10.2 clients using autofs. I'm using indirect mount for Homes. but when i do find . in a user home I saw from the dir i automount :
my map is :
/nfs auto.indirect
auto.indirect is :
users srv:/export/users
if my Home is /nfs/users/toto, i saw from /nfs/users ! if i try ls ../../../../toto from my dir it works, if I try ls ../../../../.. i saw from /nfs/users ! does anyone have an idea for me ?

Mr LAMARTA,

Your question sounds interesting. It sounds like the mount point has gotten a little confused, does it not? I am wondering if you get the same behaviors with the legacy "User space" automounter. You would need to disable AUTOFS in the /etc/rc.config.d/nfsconf file.e.g. AUTOFS=0, but leave AUTOMOUNT=1. You would need to reboot that NFS client, too.

If problem goes away, you have a workaround identified (use the legacy automounter). Otherwise, I would suspect a possible configuration problem, or alternatively, one that might require updating the NFS patch to PHNE_25234 or better plus the current libc patch e.g. PHCO_25640. The NFS patch has multiple dependencies.

As a general note, I find that debugging Automount problems in general is assisted greatly by putting the automountd (or automount if not using AutoFS) in to debug mode. A kill -17 against the PID will do that. Look for messages to be logged to /var/adm/automount.log, including enable/disable of debug logging. Do this before the mount of the directory occurs. Only mount/umount attempts are logged as you can imagine.
In addition, I find cat /etc/mnttab is very helpful to inspect the mount points at time of failure.

Hope this helps,

Hi Brian !

as you said, I've tried to downgrade to the old AM. then It worked as expected ! I think there really is a pb on autofs !
I 've turned on the log, but while tailing -f the automount.log nothing was wrong !i then switched off the debug mode... :-(
I hope HP support can help me. Thanks for your way of testing it was very usefull. Note : a Linux server and Autofs works fine on AIX, SOLARIS and Linux, and 11.0 also. Maybe it's time to finish with 10.2 ;-).
If i could....I would !

HI you all
I've just been notified by HP that ther really is a problem on autofs running on 10.2 clients with LINUX NFS servers.

The labs are now looking for a solution. maybe a patch will soon be available. wait and see. ;-)
