[Debian-ha-maintainers] Bug#711043: corosync: /etc/init.d/corosync stop freeze

[Arturo Borrero Gonzalez]

Package: corosync
Version: 1.4.2-3
Severity: normal

Dear Maintainer,

in some circumtances, when '/etc/init.d/corosync stop' is called, the script hangs forever.

In /var/log/syslog, there are many messages like these:

[...]
Jun  4 10:14:12 rasca corosync[2179]:   [pcmk  ] notice: pcmk_shutdown: Still waiting for crmd (pid=2210, seq=6) to terminate...
Jun  4 10:14:42 rasca corosync[2179]:   [pcmk  ] notice: pcmk_shutdown: Still waiting for crmd (pid=2210, seq=6) to terminate...
Jun  4 10:15:12 rasca corosync[2179]:   [pcmk  ] notice: pcmk_shutdown: Still waiting for crmd (pid=2210, seq=6) to terminate...

Jun  4 10:16:12 rasca corosync[2179]:   [pcmk  ] notice: pcmk_shutdown: Still waiting for crmd (pid=2210, seq=6) to terminate...
[...]

I have some resources configured in Pacemaker, and some are misconfigured.
So, this bug is just to ask for killing the daemon harder (maybe -9 ?) after a timeout.

Please, let me know if you would like me to write a patch for the init.d script that implements a timeout in the stop operation.
Also, please let me know if you think this is not an important issue.

Regards.
