What to do with a lost master node after failover? Return it or recreate it?

After a failover, the lost master node is usually not simply returned to the cluster, as it may be in an inconsistent state or contain outdated data. The best practice is to recreate it or perform a full reinitialization.

This ensures that the new master node is synchronized with the current state of the cluster and will not cause data or consistency issues.

If the infrastructure allows, the recreation process can be automated to minimize downtime and human error.
