Nagios Clustering for failover using drdb?

[Jelle Smet]

Hi list,

We're looking into a some techniques to have reliable fail over capability
for our Nagios server.
We were thinking about an active/passive setup, with the passive one to
become alive when the primary node goes down.

We are looking to our options how to make sure the passive node has the
latest state of the monitoring results.

The documentations suggests to tackle this with nsca and ocsp
(http://ussrvud-mon01/nagios/docs/redundancy.html).

We are thinking to use drdb on a dedicated lan to sync the rrd's, config
files and the nagios state and log files.
This should, to our opinion, work relatively well.

Are there any people doing something similar for the moment?
If so, are there any constraints, tips or things to take into account?

Thanks in advance,
