see my first posting. The howto on that subject is incomplete. As I have thought
this is the right place to discuss, I decided to present my thoughts. 

I repeat in short:
http://www.clusterlabs.org/wiki/Nagios3_on_Pacemaker_DRBD ist incomplete in two
1. uid:gid problem on shared device when not exactly matching on all hosts,
which really can happen (I believe on any linux version, I use debian squeeze)
2. check of config file fails on corosync start because it's not available. I
was thinking which solution would be most elegant and failsafe. I think it's a
good idea to add these steps to the howto. I cannot comment on the clusterlabs
wiki. I hope the author of the named howto reads here as this mailing list is
directly linked on http://www.clusterlabs.org/wiki/Mailing_lists
