Hi Remi,
That's good to know. I had thought about messing around with the
startup order.
As for the shutting down, if you watch the logs, you should see that
corosync shuts down cleanly when running stopping it with the init
script. It just takes another 5-10 seconds longer than the script is
willing to wait. Perhaps there's a way to make the init script wait a
little longer (I haven't looked into it, as I've always been watching
the logs.) It has stopped cleanly 100% of the time as long as I wait.

Hi Ray, thanks for the response.
I've tracked down the issue as far as some sort of conflict between the
following scripts in /etc/rcS.d:
S59corosync
S70screen-cleanup
S80bootmisc.sh
S85urandom
S90console-screen.sh
With the startup sequence given above, the problem seems to occur close
to 100% of time (actually, I've never seen an actual correct startup of
corosync after boot).
I believe that the problem seems to revolve around the sockets that
corosync uses in /var/run/*, thus I am assuming that one of the scripts
that executes after corosync in that sequence messes up some of the
/var/run/* files that it needs to communicate back-and-forth between all
of it's children. I've looked through the scripts (although not really
closely) and haven't been able to find the culprit.
However, I have managed to "fix" (work-around) the problem by moving
S59corosync to S95corosync. i.e.,
mv /etc/rcS.d/S59corosync /etc/rcS.d/S95corosync
Since doing that on my system(s), I've rebooted 10 times, and corosync
(and all of it's children) have come up correctly all ten times.
I'm moving on to another problem with the corosync init.d scripts now:
"/etc/init.d/corosync stop" seems to fail 100% of the time, and I
believe it to be related to timeouts (i.e. the init script simply isn't
giving corosync enough time to shutdown), I'll post back to this list
once I have more information on that.
I haven't encountered the problem where corosync fails during a manual
start -- it has only been automatic/on-boot starts that have caused
problems, and those only when it was at /etc/rcS.d/S59corosync.
Thanks.

Hi Remi,
I have not found a solution. I thought about adding it to rc.local,
but now I'm finding that starting the thing manually doesn't always
work either (especially after a hard-shutdown by pulling the power
cable).
I've found that I have to do this on a hard-shutdown:
1. Start corosync, tail syslog and notice that the processes in
/usr/bin/heartbeat/ that start up (cib, lrmd, etc) are screaming that
they can't get going for some reason.
2. Stop corosync (/etc/init.d/corosync stop), then manually kill all
those procs since they won't quit on their own.
3. Stop corosync again, just for good measure.
4. Start corosync. Watch the logs. Sometimes it says a few things
and exits again (with no indication in the logs why it exited).
5. Start corosync one more time, if it went away, and it runs great.
So.. After further reading, I decided that it probably isn't wise to
start pacemaker automatically on boot-up anyway. From what I've read,
I fear I might run into a STONITH death-match.

Hi, Ray.
I'm in the process of playing around with the pacemaker-openais
1.0.5+hg20090813-0ubuntu2~hardy1 package on Ubuntu Hardy Heron, and I
encountered the issue that you wrote about on the
[email protected] mailing list.
There is no follow-up conversation on the list (at least none that I
can see), so I was wondering if you had found a solution to the
problem with pacemaker/corosync startup during system boot?
Thanks.
