[Pacemaker] Cluster Refuses to Stop/Shutdown
I posted this to the OpenAIS Mailing List (open...@lists.linux-foundation.org) yesterday, but haven't received a response and upon further reflection I think that maybe I chose the wrong list to post it to. That list seems to be far less about user support and far more about developer communication. Therefore re-trying here, as the archives show it to be somewhat more user-focused. The problem is that I'm having an issue with corosync refusing to shutdown in response to a QUIT signal.

Re: [Pacemaker] Cluster Refuses to Stop/Shutdown
I've spent all day working on this; even going so far as to completely build my own set of packages from the Debian-available ones (which appear to be different than the Ubuntu-available ones). It didn't have any effect on the issue at all: the cluster still freaks out and becomes a split-brain after a single SIGQUIT. The debian packages that also demonstrate this behavior were the below versions: cluster-glue_1.0+hg20090915-1~bpo50+1_i386.deb corosync_1.0.0-5~bpo50+1_i386.deb libcorosync4_1.0.0-5~bpo50+1_i386.deb libopenais3_1.0.0-4~bpo50+1_i386.deb openais_1.0.0-4~bpo50+1_i386.deb pacemaker-openais_1.0.5+hg20090915-1~bpo50+1_i386.deb These packages were re-built (under Ubuntu Hardy Heron LTS) from the *.diff.gz, *.dsc, and *.orig.tar.gz files available at http://people.debian.org/~madkiss/ha-corosync, and as I said the symptoms remain exactly the same, both under the configuration that I list below and the sample configuration that came with these packages. I also attempted the same with a single IP Address resource associated with the cluster; just to be sure it wasn't an edge case for a cluster with no resources; but again that had no effect. Basically I'm still exactly at the point that I was at yesterday morning at about 0900.
