[Debian-ha-maintainers] Bug#690342: corosync: cannot set lrm parameters

[root]

Package: corosync
Version: 1.4.2-3
Severity: normal

Dear Maintainer,

I need to set the lrm max-children parameter when corosync/pacemaker starts as it is not persisted, but the corosync init script provides no way to do this. I have inserted the following code into /etc/init.d/corosync:

        maxwait=10
        while [ $maxwait -gt 0 -a "`pidof lrmd`" = "" ]
        do
                echo waiting $maxwait
                maxwait=`expr $maxwait - 1`
                sleep 1
        done
        /usr/sbin/lrmadmin -p max-children 16

 at the end of the start function, but something a bit more flexible is required. Also the "wait 10 seconds for lrmd to appear" code might be a a bit fragile - it might still be possible for lrmd to have started but not be ready to accept lrmadmin requests so the script could race.

I'm thinking something along the lines of LRM_MAX_CHILDREN= in /etc/default/corosync file and parsing that in the init script.
