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.

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!
