Pivotal Cloud Foundry MySQL 1.9 and 1.10
When a node cannot rejoin the cluster automatically a PCF operator needs to manually force a MySQL node to rejoin, the procedures are explained in this article.
If your cluster is experiencing downtime or is in a degraded state, Pivotal recommends the following workflow for gathering information to diagnose the type of failure the cluster is experiencing https://docs.pivotal.io/p-mysql/1-9/troubleshooting.html#diagnosing.
This procedure removes all the data from a server node, forces it to join the cluster, and creates a new copy of the cluster data on the node.
Note- Do not do this if there is any data on the local node that you need to preserve.
- Log into the node as root.
