I need advice implementing High Availability software (pacemaker) to create an HA cluster for services on VMs on RHV.
We're using RHV4.2.
RHV provides HA for VMs, not for services on VMs.
We have to create a cluster of two VMs with a shared disk and use pacemaker, stonith ...etc to provide HA for the services and resources that comprises the cluster.
For fencing with Stonith we will use fence-rhevm.
We need some advice implementing this cluster, should we use VM HA (RHV) in conjunction with service HA (pacemaker)?
Is there any recommendations or things to avoid?
