Nagios XI HA with shared disk

[kasune]

Hi,

We are working on Nagios XI high availability in vmware environment, This is what we have plan so far,

For redundancy two Nagios XI servers in active/passive mode. OS level(RHEL cluster) clustering for failback/failover
MySQL data and flat files in shared disk (between two Nagios XI servers)
Nagios XI will connect to local MySQL database

Nagios XI and MySQL will be added as two services to cluster suite
1. Active node
a. shared disk /data/mysql will be mount to the active server and MySQL service will start
b. Nagios XI will be start with shared flat files(hosts, services... etc) on Virtual IP for external users for access the GUI

2. Failure on Active node
a. On Active node - Nagios XI will be stop, MySQL will be stop, Fencing shared storage and umount
b. shared storage mount on Node B, MySQL start, Nagios XI start on VIP

Could you please comment on this. We have read documentation on Nagios , this is what we have came up with.

What we want
Nagios HA with real time redundancy. Not loosing the old data

OS - RHEL
OS cluster - RHEL cluster suite
virtual machines on vmware
Accessible to Nagios agents from both Nagios XI servers
