Description Michael Strawbridge 2005-03-17 20:29:39 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.3) Gecko/20050104 Red Hat/1.4.3-3.0.7

Description of problem:
Enterprise Linux 4 automounter does not unmount directories after the timeout expires ... they remain mounted although not used anymore. Restarting the automounter manually will unmount the unused directories.

I read about this same problem related to the linux 2.6 kernel and automount 4.1.3 in the kernel.org mail archives beginning at message:

http://www.mail-archive.com/autofs@linux.kernel.org/msg03967.html

They described the same symptoms I am seeing.




Version-Release number of selected component (if applicable):
autofs-4.1.3-67

How reproducible:
Always

Steps to Reproduce:
1. Set up automounter to use "--timeout" with some value
2. mount the directory on a client system with 'ls'
3. wait for timeout to expire ... it never unmounts

Comment 1 Chris Feist 2005-03-17 20:44:32 UTC

Can you provide your automount maps?  (/etc/auto.master, and any other relevant
maps).

What value are you using for --timeout?

Are you using YP or LDAP maps?

Comment 2 Michael Strawbridge 2005-03-17 20:56:06 UTC

No YP or LDAP maps ... very simple ... only a single file map for home
directories. We are using "--timeout=300" from /etc/sysconfig/autofs:
DAEMONOPTIONS="--timeout=300"

auto.master
----------------------------------------
#
# $Id: auto.master,v 1.3 2003/09/29 08:22:35 raven Exp $
#
# Sample auto.master file
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# For details of the format look at autofs(5).
#/misc  /etc/auto.misc --timeout=60
#/misc  /etc/auto.misc
#/net   /etc/auto.net
#
# Only home directories are automounted for now ...
/home   /etc/auto.home

-----------------------------

/etc/auto.home looks like this:
-------------------------------------
straw -rw,hard,intr home.clust.server:/san/dir1/&
mike -rw,hard,intr home.clust.server:/san/dir2/&
dave -rw,hard,intr home.clust.server:/san/dir1/&

...

Comment 3 Chris Feist 2005-03-17 21:04:54 UTC

Can you provide the output of the 'service autofs status' command as well as the
contents of /etc/sysconfig/autofs

Thanks,
Chris

Comment 4 Michael Strawbridge 2005-03-17 23:29:08 UTC

$ service autofs status
Configured Mount Points:
------------------------
/usr/sbin/automount --timeout=300 /home file /etc/auto.home

Active Mount Points:
--------------------
/usr/sbin/automount --timeout=300 /home file /etc/auto.home

*************************************************************

$ cat /etc/sysconfig/autofs
# Define custom options in /etc/sysconfig/autofs
# Use LOCALOPTIONS for defining variables, e.g. OSREL
# Use DAEMONOPTIONS to define the unmount timeout
# Define UNDERSCORETODOT as 1 to convert
#     auto_home to auto.home and auto_mnt to auto.mnt
# Mount options, e.g. rsize=8192, should go in auto.master or
#     the auto_* map entry for a specific mount point
#
LOCALOPTIONS=""
DAEMONOPTIONS="--timeout=300"

#  UNDERSCORETODOT changes auto_home to auto.home and auto_mnt to auto.mnt
UNDERSCORETODOT=1
DISABLE_DIRECT=1

Comment 5 Chris Feist 2005-03-31 16:07:26 UTC

Can you cd into that directory.  Verify that it's mounted.  Then cd to '/'. 
Then run 'lsof | grep home'.  Then wait 400 seconds without doing anything,
verify that the directory is still mounted and run 'lsof | grep home' again. 
Can you post the output of both runs of lsof?

Comment 6 Michael Strawbridge 2005-03-31 20:17:41 UTC

This is an active system, so there are quite a few home directories mounted
already. The test case was to mount a home directory not already mounted ...
I ran "ls /home/hung" to get that directory mounted ... checked ... verified it
mounted ... cd / and ran 'lsof | grep home' and got this:

Comment 7 Chris Feist 2005-03-31 20:42:00 UTC

Ok, next I need you to enable --debug on autofs.  Change the line in
/etc/sysconfig/autofs from:
DAEMONOPTIONS="--timeout=300"
to:
DAEMONOPTIONS="--timeout=300 --debug"

Also add this line to your /etc/syslog.conf file:
*.* /var/log/debug

Then restart syslog (service syslog restart)
and restart autofs (service autofs restart)

Then ls an autofs directory, make sure it's mounted then wait 400 seconds, run
df and make sure that it's still mounted.

Then take and post your /var/log/debug file from when autofs started until the
final df.

Comment 8 Michael Strawbridge 2005-04-01 12:29:42 UTC

OK ... here it is. The automounted directory I used for this test is /home/hung.

Comment 9 Chris Feist 2005-04-01 17:48:06 UTC

It looks like autofs couldn't restart because /home was in use.  Try 'service
autofs stop'.  Then do a 'ps -eaf | grep automount' to make sure it's down. 
Then startup autofs ('service autofs start') and post the /var/log/debug logs.

Comment 10 Michael Strawbridge 2005-04-01 19:47:47 UTC

Right ... autofs wouldn't stop because there are other /home automounted
directories. Unfortunately this is a production system and I cannot kick off all
users .. which is what is needed to relinquish all /home automount points.

Comment 11 Jeff Moyer 2006-02-27 17:31:36 UTC

We're still waiting for debug logs on this one.

Comment 12 Jeff Moyer 2006-05-23 17:13:52 UTC

Is this problem still occurring?  Can you provide the requested debugging
information?
