Issue

After updating one node in our CTDB cluster we are unable to join to the cluster due to the error : "CTDB Cluster with mixed versions, cannot continue".This occurred during patching.

Our standard process is to take a node out of cluster, patch it, rejoin to cluster, fail services over, and repeat on second node.
Without being able to do this, we are currently unable to rejoin one of our nodes to cluster.
