can not automount

Pelephone System — Wed, 11 Apr 2007 08:30:29 GMT

Hi everyone!

I am try to set up automount on 11i machine (my first time doing that) . I have configured nfsconf and auto_master file for the requierd nfs, when running automount -v I get a message that the FS was mounted , in /etc/mnttab I can see the mounted fs , and still no files appear in the mount dircetory. Also , trying to write to the dircetory hangs the shell.
Please help.

Check the /etc/exports entry on the NFS server to see how the FS was exported.

What is the NFS server system in this case?
The problem could be at the other end. Can
any other system get good NFS access to the
same remote file system?

The NFS System is HP-UX . I forgot to say that regular mount of the same NFS on the same server works fine.

Shalom,

Please post the contents of the auto_master and files it points to. There is probably a problem there.

Shalom,
I`ve defined everything in the auto_master:
root@unixlab2: cat /etc/auto_master
/net -hosts -nosuid,soft
/my unixlab1:/home/testleo/automount
root@unixlab2:
root@unixlab2: cat /etc/mnttab
-hosts /net autofs ignore,indirect,nosuid,soft 0 0 1176296055
unixlab1:/home/testleo/automount /my autofs ignore,indirect, 0 0 1176297283

Pesah beseder, haiti be hul :)

Hi,

you do not use /etc/aut_master correctly: This file is the so-called master map and contains maps only - not single mount entries.
root@unixlab2: cat /etc/auto_master
/net -hosts -nosuid,soft
/my unixlab1:/home/testleo/automount

Create a file /etc/auto.mymap containing
unixlab1 &:/home/testleo/automount

Change /etc/auto_master to
/net -hosts -nosuid,soft
/my /etc/auto.mymap

And after a 'automount -v' you can see the NFS directory under
ls /my/unixlab1

I`ve tried what you suggested and the result is pretty much the same:
ls /my does not show anything ,
ls /my/unixlab1 hangs the shell.

Hi,

- you should check for NFS related messages in /var/adm/syslog/syslog.log

- check order of the name resolution:
grep auto /etc/nsswitch.conf

- is the result of NFS-mounting this directory without automount the same?
mkdir /other
mount unixlab1:/home/testleo/automount /other
ls /other

NFS mount without automount works fine.
root@unixlab2: mount unixlab1:/home/testleo/automount /my
root@unixlab2: ls /my
1 2 3 lost+found
root@unixlab2:

Ok, let's start over.

Post the following here:

# cat /etc/auto_master
# cat
# cat /etc/mnttab

I want to see exactly how your automounter is configured before moving forward.

Hi ( I am the author of the thread , I switched user ) .
I have updated patches on the system , and now the situation is a little better , trying to write to the automount directory does not hang the shell , but I do get an error :
root@unixlab2: touch a
touch: a cannot create
Still cant see the files of the mount.

Now, for what you have asked:
root@unixlab2: cat /etc/auto_master
/net -hosts -nosuid,soft
/my /etc/auto.mymap
root@unixlab2: cat /etc/auto.mymap
unixlab1 &:/home/testleo/automount
root@unixlab2: cat /etc/mnttab ( irrelevant lines where removed )
-hosts /net autofs ignore,indirect,nosuid,soft 0 0 1176387571
/dev/vg00/lvol10 /test vxfs log 0 0 1176625492
/etc/auto.mymap /my autofs ignore,indirect 0 0 1176625705

Thanks for your help.

Hi,

please help me to sort this

<<

What is the result of
ls /my/unixlab1
ls -ld /my/unixlab1
and then
grep /my /etc/mnttab

As a root user, you have no special privilegs on the remote system, so
touch /my/unixlab1/newfile
would require world-open acces rights at
/home/testleo/automount on unixlab1.

Shalom gam.

In one session:

tail -f /var/adm/syslog/syslog.log

Then start the automount service and try the change directory.

First to Petter:
The unixlab1 dir was never created in /my
so ls on its variations will not give any result.
I think I do have the permissions to that NFS , if I mount without automount I can write to it.
Now, SEP:

Another weird thing that is happening is that the automound does not write anything to syslog nor to /var/adm/automount.log...

Thanks for your help.

Sorry I forgot the mnttab:

/etc/auto.mymap /my autofs ignore,indirect 0 0 1176807176

Hi,

keep in mind, that the directory
/my/uniylab1
may NOT be visible by a simple
ls /my

It first gets mounted when trying to access
/my/unixlab1
explicitly via
ls /my/unixlab1

If that last command does not produce any output, the automount is not triggered correctly.

Leonid Mishkind — Tue, 17 Apr 2007 08:25:45 GMT

cd /my/unixlab1/
ls

does not produce any output also.

Re: can not automount

Peter Nikitka — Tue, 17 Apr 2007 08:37:28 GMT

Hi,

having done the
cd /my/unixlab1/
then now send us

grep /my /etc/mnttab
tail /var/adm/syslog/syslog.log
