autofs failed
 

Hi,

I'm testing the function"autofs" on Ubuntu16.04 x64.
https://askubuntu.com/questions/8843...fs-via-autonfs

Things I've done were:
1. file: /etc/auto.master
/mnt /etc/auto.test
2. file: /etc/auto.test
nfs -fstype=nfs 10.100.7.34:/home/paul/nfs
3. restart the autofs service.

But when I access to /mnt, the result likes:
$mount | grep mnt
/etc/auto.test on /mnt type autofs (rw,relatime,fd=6,pgrp=1131,timeout=300,minproto=5,maxproto=5,indirect,pipe_ino=20992)

However I'm sure the destination could be mounted manually with the command:
mount -t nfs 10.100.7.34:/home/paul/nfs /mnt

why autofs failed?

many thanks,
Paul

Why do you think it failed? Did you get an error message?

Hi Sean,

Thanks for your replay.
No error message was responsed,
Since there are some files in 10.100.7.34:/home/paul/nfs,
but can't see anything in /mnt, so I think it was not been mounted expectedly

Thanks
Paul

Can you see the files in /home/paul/nfs?

On my system mount on returns a list of mount points, it doesn’t show what’s in them...you appear to have one for /mnt, yes?

Yes, I can see files in /home/paul/nfs
The mount point I saw is
/etc/auto.test on /mnt type autofs (rw,relatime,fd=6,pgrp=1131,timeout=300,minproto=5,maxproto=5,indirect,pipe_ino=20992

Welcome to LinuxQuestions

The ArchWiki is a good reference for configuring Autofs
https://wiki.archlinux.org/index.php/autofs

What happens if you try going to /mnt/nfs from the command line.

cd /mnt/nfs

With the entry in auto.master you defined that /mnt is contolled by auto.test. Each key in auto.test is a further directory in /mnt.
Your first and perhaps yet only key is "nfs".
So you must access /mnt/nfs in order to have autofs attempt to mount it there.
When no longer accessed the /mnt/nfs will be unmounted after some time and disappear.
If you find it confusing that /mnt appears empty, then you can add a -browse option in auto.master:
/mnt /etc/auto.test -browse
Then, when looking in /mnt with ls -l, the keys appear as directories, with arbitrary attributes if not yet mounted.

Thanks a million guys!
