[Pacemaker] Following the clusters from scratch v2 document, and coming up with weird (erroneous?) errors...

[Colin Hines]

Okey dokey, I've done some further troubleshooting and started again from
scratch on a new node.  I'm performing this setup on a CentOS 5.5 node.
 Here's an excerpt from my messages file taken after doing a "yum -y install
pacemaker corosync"

...many more follow....


What's weird to me is that I hadn't started ANY services or run any commands
by this point, I'm thinking something in the RPM is kicking off that
cl_status command.

I believe I've determined that when rpm package
heartbeat-3.0.3-2.3.el5.x86_64.rpm is installed, that's when the errors
start occurring.  It seems like that is a required dependency for the latest
pacemaker RPM on http://www.clusterlabs.org/rpm/epel-5/.  I removed the
pacemaker and heartbeat packages using yum, and then re-added them via RPMs,
but found out that pacemaker requires the heartbeat-libs package or tools
such as crm_verify fail.  Following re-install of heartbeat-libs, pacemaker,
and pacemaker-libs with --no-deps, no more erroneous error messages.  I can
break/fix the issue by installing and removing
the heartbeat-3.0.3-2.3.el5.x86_64 package.
