problems with automount

Tarek — Thu, 08 Feb 2001 08:57:30 GMT

I have installed the patch in the attached file and from that automount stopped working. Using NIS. Before the installation automount works perfectly. Now when a user enters to this ws he has the following message:
Unable to change to home your directory....
It is not also possible to mount a remote area of another ws. If i user ypwhich command the client points to a slave, and with ypwhich -m all services points to nis master server.
The /etc/automount is configured. I don't know what to do... I wonder if there is a patch that resolves this problem or one that must be installed after the patch i previously installed. OS hpux 10.20, workstation Visualize C3000.
Thanks Tarek

Hi Tarek,

I think you should install the latest s700_800 10.20 NFS/NIS cumulative megapatch (PHNE_22288) as it solves quite a few automount issues.

Best regards,

Hello Tarek,

Have a look at /etc/auto_master file. Supposing that your master map is called auto.master, then /etc/auto-master should contain the line:
+auto.master

If using autofs, you can force the re-reading of the map by entering:
automount -f /etc/auto_master -v

You should see the output "/home remounted".

If it does not solve the problem, then try to install the patch as advised by Dan.

Best regards.

Fred.

My /etc/auto_master is:
/net -hosts -hard -timeo=14 -retry=3 -rsize=4096 -wsize=4096
where should i put the +auto_master

Tarek,

It does not matter. The thing is one entry per line.
So your /etc/auto_master would eg. look like:

+auto.master
/net ...

Bests,

The auto_master is read on each local ws, it doesn't read the nis server's one.
I have modified the nsswitch.conf and put automount=files[NOTFOUND=continue] nis but without success. Then i modified the auto_master and in it is only written:
/net -hosts -hard .In this way it works slowly and not always, but i don't have error message unkown user, i don't know why. When i enter as a user of that ws, su - user, his home directory is mounted by net. This is wrong, it might be read locally. (on all other ws works in this way). I think the problems is concerning auto_master and nsswitch.conf.
If i see what process is running when i start nfs.client (ps -ef | grep automount) on all ws the process is:
/usr/lib/netsvc/fs/automount/automount -f /etc/auto_master, but on that ws the process is:
/usr/sbin/automountd.
Why this difference? I hope i've been clear.

Sorry all for not explaining good, maybe i've been confusing. We use nis in our company, but not for automount. The /etc/auto_master is read on each workstation.
I've solved the problem. It was the /etc/rc.config.d/nfsconf in which there was a parameter AUTOFS=1 that might be 0. I checked it with the other workstations, that was the cause of the different automount process. However thanks all and sorry again for confusion.

There are two versions of automount:
/usr/lib/netsvc/fs/autofs/automount (new)
/usr/lib/netsvc/fs/automount/automount).

The new one starts /usr/sbin/automountd. So I think you use both versions on different workstations. Look in the /etc/rc.config.d/nfsconf file: AUTOFS=1 for the new and AUTOFS=0 for the old one.

Tarek,

Happy that you were able to solve your problem :o)

I think you should go and have a look at the following doc:
http://docs.hp.com/hpux/onlinedocs/B1031-90045/B1031-90045.html

In chapter Configuring and Administering NFS, you have two relevant parts that may help you making distinction between both NFS automounters:

* Configuring and Administering the NFS Automounter
* Configuring and Administering AutoFS

I know there was a doc explaining pros and cons between both automounters, but I can't remind where it was.

I hope this helps !

Bests,

Fred.
