    Hi Christoforos,

    As stated in the error, ClusterControl allows only one node to accept write (read_only=OFF) in one given cluster during the import process for accurate topology detection. In your setup, it seems like A and B are writable. Simply set B to read_only=ON before the import process. You can change it back to read_only=OFF once the import process completes.

    Hi Christoforos,

    I'd like to emphasize here that despite supported by ClusterControl, if you are running with more than one writable master in a replication setup, you are exposed to a certain risks e.g, cluster recovery won't work accurately and load balancer integration for read/write splitting will also be a problem.

    Hello Ashraf,

    Thanks for the replay :)

    Load balancer integration from the Cluster Control ?

     

    Best regards, :) :P
