Enabling HA in your Proxmox cluster is a step in the right direction. However, it doesn't always mean your app will recover from a failure. I take a look at five practical checks for your HA. We cover host failure, network partitions and fencing, recovery-node compatibility, storage availability, and application failures inside a running VM. The goal is to see when the application becomes usable again, which is better than simply watching the VM restart.
