Bugzilla Bug 110887

I really don't know what information is useful to provide here, but I'll give
it
a try:

olympia ~ # /etc/init.d/autofs start
 * Starting automounter ...
{different mountpoints}     [ ok ]
olympia ~ # /etc/init.d/autofs start
 * WARNING: "autofs" has already been started.
olympia ~ # /etc/init.d/autofs status
 * status:  stopped
olympia ~ # /etc/init.d/autofs start
 * Starting automounter ...
{different mountpoints}     [ ok ]

The maps contain some more extended syntax, like
 rfaustin -nosuid,intr   cragganmore:/volume1/users/students/&
 * -nosuid,intr  lesse:/volumeC/students/&

Also, the mountpoints that were not busy (locked by someone having cwd in that
mountpoint) at the time of the status-command, are effectively unmounted.  The
automount daemons dissappear as well.

/var/log/everything/current doesn't contain anything between the start and the
status command: (where the status command effectively does a stop)
Oct 30 14:27:01 [rc-scripts] WARNING: "autofs" has already been started.

For me "/etc/init.d/autofs status" does what is supposed, it shows the status
and does not change it.
My autofs-version is net-fs/autofs-4.1.3-r7.

Created an attachment (id=96565) [details]
zzam's emerge info

I have the exact same autofs version, the problem still remains.  

I do notice that when I disable "ldap" in /etc/nsswitch.conf, the problem
doesn't show.  A "/etc/init.d/autofs stats" then gives like:
Active Mount Points:
--------------------
/usr/sbin/automount --timeout 60 --pid-file /var/run/autofs.software.pid
/software ldap
ou=auto.software.linux-i386,ou=Automount,dc=esat,dc=kuleuven,dc=be -d -D
TYPE=linux-i386 -v

When re-activating ldap in nsswitch.conf, I get this (after restarting autofs,
before trying to do "/etc/init.d/autofs status"):
Active Mount Points:
--------------------
/usr/sbin/automount --timeout 60 --pid-file /var/run/autofs.software.pid
/software ldap
ou=auto.software.linux-i386,ou=Automount,dc=esat,dc=kuleuven,dc=be -d -D
TYPE=linux-i386 -v
/usr/sbin/automount --timeout 60 --pid-file /var/run/autofs.cdroms.pid /cdroms
ldap nisMapName=auto.cds,ou=Automount,dc=esat,dc=kuleuven,dc=be -d -D
TYPE=linux-i386 -v
/usr/sbin/automount --timeout 60 --pid-file /var/run/autofs.esat.pid /esat ldap
nisMapName=auto.net,ou=Automount,dc=esat,dc=kuleuven,dc=be -d -D
TYPE=linux-i386 -v
--- cut ---
and much much more (about 31 automounts in total)

I probably should note that there's one automount failing to start, could this
have something to do with the problem.  If I had write access to the
ldap-database, I would have tried removing the entry.  

I have no further clue on how to debug this, all ideas are welcome.  

Looking further into this, I noticed that:
- if I remove the automount that's failing to start correctly, everything is ok
- if I don't pass the --pidfile option to start-stop-daemon, everything is ok
- if I disable the storing of the automount-parameters as an append to the
pid-file, everything is ok

Exploring the third option:
the start() part of the autofs-init-script contains:
    if [ $? -ne 0 ]; then
      eerror "Failure on $mnt"
    else
      echo "${params}" >> $pidfile
    fi
but $? (return status of start-stop-daemon) is 0, as the automount-daemon first
daemonizes and only then almost immediately kills itself (because it can't load
the map).  Hence the parameters are written to the pid-file, even though the
file didn't previously exist, creating a new file that doesn't contain a valid
pid-number.  

I would like to note that the pidfile is created by the daemon also after
daemonizing. So roughly there are two possibilities:
- pidfile is firstly created by the automount-daemon, then $params is appended
- $params is written to pidfile, then automount-daemon recreates the pidfile

As I also don't see where the added $params-information to the pidfile is used,
I'd like to propose to remove the 5 lines of code I pasted above.  

I just ran into this same issue.  I ran rc-status (which in turns calls
/etc/init.d/autofs status) and was watching my syslog at the same time and
watched all my automounts shutdown except my home directory and an apps
directory that were in use.

Looking at the /etc/init.d/autofs script, there is no status() function defined
there, so I suppose this is from /etc/init.d/runscript.sh.  I know nothing
about the /sbin/runscript that is apparently the interpreter for init scripts.

Unlike Stefaan in comment #3, I do not have ldap in my nsswitch.conf and
building autofs with the ldap USE flag off or on does not make any difference.

I'm interested to see your autofs-configuration. Could you post auto.net or
similar?

Here's my /etc/conf.d/autofs

whardin@freeman ~ $ grep -v "#" /etc/conf.d/autofs
localoptions=''
daemonoptions='--timeout 60 -g -v'
nis_mapname='auto.master'

I won't post my auto.master, but I will describe it.

One entry, /autofs, that points to a local automap for pluggable devices and
other oddities for my workstation.
40 entries for NIS automaps for company data.  All confirmed valid.

I've not had any other problems with autofs in recent memory.

Unfortunately I don't know how to trace/debug what happens from the time I hit
enter.  I think it's safe to say it doesn't actually call the stop() function
defined in /etc/init.d/autofs because the ebegin output "Stopping automounter"
is not seen (for me anyways).

Here's a sample of whats in the syslog:
Nov 13 13:44:52 freeman automount[15034]: rm_unwanted: /autofs/shuffleboard
Nov 13 13:44:52 freeman automount[15034]: rm_unwanted: /autofs/rhel
Nov 13 13:44:52 freeman automount[15034]: rm_unwanted: /autofs/netapp
Nov 13 13:44:52 freeman automount[15034]: rm_unwanted: /autofs/misnts7-mis
Nov 13 13:44:52 freeman automount[15034]: rm_unwanted: /autofs/jumbo
Nov 13 13:44:52 freeman automount[15034]: rm_unwanted: /autofs/floppy
Nov 13 13:44:52 freeman automount[15034]: rm_unwanted: /autofs/cdrom
Nov 13 13:44:52 freeman automount[15034]: rm_unwanted: /autofs/burn_staging
Nov 13 13:44:52 freeman automount[15034]: rm_unwanted: /autofs/bbot_archive
Nov 13 13:44:52 freeman automount[15034]: shut down, path = /autofs
Nov 13 13:44:52 freeman rc-scripts: status:  stopped

Just curious, if you remove the 5 lines in /etc/init.d/autofs, as I suggest in
comment #4, then restart autofs and then ask for a status, does it behave
better?

I made the changes proposed in comment #4

Before:
autofs.engtools.pid
17536
--timeout 60 --ghost --verbose --pid-file /var/run/autofs.engtools.pid
/engtools yp auto.engtools

After:
autofs.engtools.pid
6759

The behavior of "/etc/init.d/autofs status" does indeed improve after this
change.

Since some .pid files did not exist due to remaining open between the stop and
the start, I echoed the PID of the automount process into a new .pid as defined
on in the 'ps -ef' listing.  Either I messed up or this broke it because after
that doing the 'status' caused autofs to stop again.

I finally forced all automount processes to shutdown, removed all the mounts,
and restarted the autofs service.  With no errors when starting autofs, status
works just fine, but I have been known to restart autofs and still have
lingering processes hanging around because my email and user directory are NFS
auto mounted, so I feel that I will probably run into this problem again.

Bug is still in there today...

/etc/init.d/autofs status calls
  svc_status inside /sbin/runscript.sh
  which calls update_service_status inside rc-daemon.sh

which looks up all started daemons associated with autofs by looking into
  /var/lib/init.d/daemons/autofs

if one of those services is not running anymore, update_service_status
effectively runs /etc/init.d/autofs stop, killing all working automounts

Planning to solve this the way I suggested in comment #4 (as I still see no use
for the parameters to be inside the pid-file)

Reassigning to myself

Fixed in net-fs/autofs-4.1.3-r8
