Not without knowing your setup better.
If you are new, I would start by building a cluster from scratch, using
your production environment as a guide. This will go a long way to help
you both find the files you need and also to help you develop a good
understanding of your production environment and how clustering works.
It's very well worth the time investment. :)

thanks Digimer,
but I cant poweroff the nodes .. they are in production and shouldn't be
touched ...
can you tell exactly which files /"Copy over the various config files"/

That is a lot harder to do... The easiest would be to power off the
nodes and clone the systems (adjusting on boot for things like
different MAC addresses, avoid duplicate IPs, etc).
In truth though, for dev/testing, I don't think you need to do this.
Copy over the various config files, copy the data from the FS on
DRBD from backups and have at it. I actually think the practice of
rebuilding (repeatedly in a dev environment) what you have in
production is a great way to know if you're ready to do it in an
emergency.

Yes .. everything not only DRBD ... to a fully working replica of
everything (including content)
thanks in advance

For DRBD, assuming the installed versions matched, you just
need to
copy /etc/drbd*.
Or are you asking about replicating the contents of the
resources as
well?

Hi,
is there away to replicate a production cluster ( with
DRBD-Corosync-Pacemaker) .. and build an exact clustering
software on a
development setup?
and what would be the easiest/fastest/most accurate way
to do so ...
thanks!
