[Bug 768846] Re: autofs does not mount /net/host

[Jens Langner]

Here I am having the same problem with our server since we upgraded them
to 11.04 (natty):

-- cut here --
langner at mars:~$ ll /net/cns2/
ls: cannot access /net/cns2/: No such file or directory
langner at mars:~$ ll /net/cns2/.

In addition, we identified that when setting a very short autofs unmount
timeout (via "--timout X" option) this timeout is never reached and the
mount point which was automounted stays forever.

The interesting part to not is, that when downgrading to kernel
2.6.35-30-server from 10.10 (Maverick) the problem instantly vanishes as
you can see here:

-- cut here --
langner at mars:~$ ll /net/cns2/
total 0
drwxr-xr-x 2 root root 0 Jul 30 15:12 NTOF
drwxr-xr-x 2 root root 0 Jul 30 15:12 archive
drwxr-xr-x 2 root root 0 Jul 30 15:12 astro
drwxr-xr-x 2 root root 0 Jul 30 15:12 projects
drwxr-xr-x 2 root root 0 Jul 30 15:12 user
-- cut here --

Thus, I also suspect a kernel problem! Please also note that even
upgrading to kernel 2.6.38-11-server which is still under development
didn't solve the problem.

In addition, please remove the incomplete status of this bug report as
we should have supplied enough information here to get some more
priority on the issue!
