I was working from I have found in the cluster.spec… there was not
Pacemaker dependency that and nothing failed with my Pacemaker.

As far as clvmd is concerned… I was not able to make it work with
Pacemaker/corosync - yes that was probably the 'dlm_controld.pcmk'
thing, but even Google couldn't help much (documentation for dlm/clvmd
that is available is close to nothing). And I don't quite understand how
the packages from cluster.spec are split (a dlm_conrold binary is in th
group subpackage which pulls cman… but I didn't want cman and it didn't
work anyway). Though, I was able to run clvmd with Pacemaker/openais/corosync
and it seems that will be a good enough solution for me. openais does
not look that scary as the stuff from cluster.spec ;)

I can see place for improvement, though.
