This means that if you're currently using packages from

network:ha-clustering:Stable instead (once we've finished shuffling

On a punt, it's probably mod_status. Check your Apache logs at the time
the start failed. If it's whining about a 403 or 404 for /server-status

I'd guess the cluster attempted to stop the resource for some reason,
but the stop failed, and STONITH is not configured. In this situation,
the cluster can't manage the resource (it's not safe

If each node can only see itself, it's presumably a networking problem

Because that constraint has a score of "inf", it'll take precedence.

You might also find that stopping the

storing ad-hoc text that may be related to something nearby, but I'd be
wary of relying on them for e.g. an alternate source of resource names,
because they're not constrained to a particular fo

Pacemaker will run a monitor op once prior to starting a resource, to
make sure it's not already running. Possibly you're seeing this monitor
op, but the init script is
and SLES 11?
linux-ha/heartbeat has been phased out in favour of openais/corosync,
and is not officially supported on SLES 11.

I expect it is of the highest quality :)

findif tries to figure out which interface should be used for a given IP
address. Check the output of "route -n" to see if there's anything
weird-looking there,

That sounds like a bug in the RA. If the resource is already stopped, "stop"
is meant to return success.
