I've got an odd problem. My server will not shutdown normally because
the AoE driver is not being shut down properly. While investigating the
problem, I found that the aoe script is apparently not being called for
shutdown. I have been able to duplicate this with a brand new test
script.
My test script is just a simple file that echos back the start or stop
command:
#!/bin/bash
#
# chkconfig: 45 01 99
# description: Test Start and stop script
#
echo "Called with $1"
I installed it with 'chkconfig --add mytest'.
The softlinks exist in the runlevel directories:
/etc/rc.d/init.d/mytest
/etc/rc.d/rc0.d/K99mytest
/etc/rc.d/rc1.d/K99mytest
/etc/rc.d/rc2.d/K99mytest
/etc/rc.d/rc3.d/K99mytest
/etc/rc.d/rc4.d/S01mytest
/etc/rc.d/rc5.d/S01mytest
/etc/rc.d/rc6.d/K99mytest
When I 'telinit 4', I can see the script output in /var/log/messages:
Dec 19 11:46:49 bnofdn1 mytest: Called with start
Dec 19 11:46:49 bnofdn1 rc: Starting mytest: succeeded
When I 'telinit 3', there is no output from this script. It is like the
script is not even being called.
Am I doing something stupid here? When I do 'telinit 3' from a higher
runlevel, isn't it supposed to run all of the 'K*' scripts in rc3.d
with
a 'stop' argument?
Any suggestions would be appreciated.

The init process only runs K* under runlevel 4 (rc4.d) when exiting runlevel 4, then runs all of the S* stuff under the new runlevel. $0.02, no more, no less .... -- William A.

It simply checks the current runlevel and then runs all the scripts in that directory (kill scripts first, and then start scripts). -- Bowie

I finally determined that the script was properly creating and deleting the lock file, it was just named wrong. The lock file must be named either 'subsys' or 'subsys.init'. This one was trying to use 'subsys-init'. Changed the dash to a period and the problem went away. Thanks for the help! -- Bowie

I should see output showing the service shutting down when I go from 4 to 3. My main point was that your description of the shutdown process does not seem to be accurate. Based on reading the 'rc' script, the runlevel switch happens first and then rc runs all scripts from the new runlevel directory. If I switch from level 4 to level 3, the system will switch the runlevel to 3 and then run the kill scripts and startup scripts from the rc3.d directory. The original problem has been solved. The script was not setting it's lock file properly, so it was being skipped when rc ran the kill scripts. Now that I've fixed that problem, I see the shutdown messages from the script as expected. -- Bowie
