Dear list,
I've one question to all of you: Does anyone of you have experiance with redundant monitoring where an OMD site is being clustered using
a shared storage with DR:BD? The idea is that you create let the
monitoring run on two servers, manage them with heartbeat/pacemaker
and us DR:BD as a common storage. Has anyone of you setup something
like that?
Greetings from Munich,

Hi Mathias,
We had a drbd-based two-server-setup in the past with nagios and pnp (but not OMD or check_mk) on CentOS 5.3
The disk-io was almost too slow when using two dedicated gigabit-links for the drbd-traffic.
In the end we had about 1000 services - most of them with pnp graphs.
From time to time we also had split-brain issues with luci and ricci so we decided to do a clean re-install.
Our new setup is a standalone virtual machine on a 4-server ESX5-cluster using VMware HA.
We are now monitoring 113 hosts and 2250 services without any problems.
I would not recommend drbd, especially if there are lots of .rrd files to process.
best regards
Florian

I asked this a few weeks ago and got an excellent
response:http://lists.mathias-kettner.de/pipermail/checkmk-en/2012-November/007768.html
I used http://blog.simon-meggle.de/tutorials/nagiosomd-cluster-mit-pacemakerdrbd-teil1/
(it's even in German for you!!) He did a follow up in english as well
with some other hints.
The one tweak I did was up the timeout for the omd status failover
(too sensitive, commits were bouncing the cluster). I changed it from
(i think) 20 to 90.
