[Bug 1050021] Re: autofs failed to mount .hidden

[Frédéric Nass]

Hi,

I confirm this bug. I'ts a real pain. Even more when using executable
maps as we do, because autofs blindly obeys to mounting a share that
doesn't exist on the server side (shouldn't autofs know it ?).

Here's our executable /etc/auto.nfs map :

#!/bin/bash
user_group=$(id -n -g $1)
echo "-fstype=nfs4,rw,sec=krb5  server:/home/NFS/$user_group/$1"

It works fine when the map is called with username when mounting its
home directory. But sometimes, it's Kate (text editor) that's trying to
access /home/.kateprojekt or /home/.kateconfig files instead of
/home/user1/.kateprojekt and /home/user1/.kateconfig and then it fails.
It's worse than that : it freezes the text editor and even the whole KDE
desktop.

That's what autofs is triyng to mount in this particular situation :
/home/NFS//.kateprojekt on /home/

Tried this with Ubuntu 13.04 server and client and Fedora 19 too and
same errors  happens. On Fedora 19 I even get error about /home/.Trash
and /home/.Trash-xxxxx and /home/.hidden etc....

I'm now on production with all my students and teachers beeing impacted
by this bug.

There seems to be 2 problems here :

1. Autofs should better handle mount errors.
2. Kate should record its configuration in the right path : /home/user1/.kateprojekt and not /home/.kateprojekt 

Hope someone pays attention to this and fix this really soon. Let me
know if I can help / try your fixing.

Frédéric.

Title:
  autofs failed to mount .hidden

Status in “autofs” package in Ubuntu:
  Confirmed

Bug description:
  I use autofs to mount network drive via NFS (Ubuntu 12.04 with all
  updates).

  Configuration files:
   /etc/auto.master:
  ------------------------
   /media /etc/auto.nfs --timeout 10

  /etc/auto.nfs:
  ----------------
  myshare -fstype=nfs4,soft,intr 192.168.1.1:/

  I made the directory /media/myshare in advance.

  First a stopped service: "service autofs stop" and run "automount -f -v" to see its messages.
  Than I tried to access /media/myshare.  ls is OK, mc from console too but when I do it with nautilus I get " failed to mount /media/.hidden" and nothing else happens. What is interesting, sometimes the first attempt works but the second fails and myshare directory is deleted!

  This is the situation on Ubuntu 12.04. At the same time the same
  configuration works perfectly on Kubuntu 12.04 with Krusader and
  Dolphin. Any ideas or workarounds?

  Note: what is wrong with autofs? There is an old "syntax error" bug
  (https://bugs.launchpad.net/ubuntu/+source/autofs5/+bug/488696) that I
  had to fix first and now this one I don't know what to do about.
