Hello everyone,

We are currently trying to setup a centreon monitoring HA cluster on debian 11 and are currently trying it out in our test network.

We installed 1 central server, 1 secondary and a poller/quorum device

We made the decision to install the HA feature described as in the official centreon documentation, unfortunately we ran in some trouble. The PCS cluster and all its resources look like they work correctly but the configuration of the primary node doesn’t get failed over, this means that in practice we have 2 different centreon installations instead of the clustered HA configuration that we want aka split brain.

The secondary node does become the primary node but it doesn’t have any of the config or hosts that we added on the primary.

We would really appreciate if any of guys could point us to the right direction.

I’ll post some examples of what I mean below.
