I did set up POC for Nagios Core on CentOS 7 using drbd+pagemaker for LAN
and WAN H.A.
for LAN HA, ie, fail-over Nagios monitoring service with-in same Data
Center is doable.
ocf-agent script for pacemaker was written already.
But in the end I did not use it since my Nagios core is in vmware farm as a
VM which use vcenter's HA to provide hardware level fail-over.
for WAN HA(fail-over Nagios service over WAN) , I ran into drbd bandwidth
issue (10ms ping time) which require proprietary drbd-proxy solution but I
didn't pursue further.
