Hello Everyone, This is the first time I'm doing cluster replication. But I stuck on Adding Instance. I don't know why this error is coming behind. "The error says The START GROUP_REPLICATION command failed as there was an error when initializing the group communication layer".
I am following this tutorial https://mysqlserverteam.com/mysql-innodb-cluster-8-0-a-hands-on-tutorial/
Thanks in Advance
NOTE: The target instance '*********' has not been pre-provisioned (GTID set is empty). The Shell is unable to decide whether incremental state recovery can correctly provision it.
The safest and most convenient way to provision a new instance is through automatic clone provisioning, which will completely overwrite the state of
'********:3306' with a physical snapshot from an existing cluster member. To use this method by default, set the 'recovery method' option to 'clone'.
The incremental state recovery may be safely used if you are sure all updates ever executed in the cluster were done with GTIDs enabled, there are no
purged transactions and the new instance contains the same GTID set as the cluster or a subset of it. To use this method by default, set the 'recoveryMethod' option to 'incremental'.
Please select a recovery method [C]lone/[I]ncremental recovery/[A]bort (default Clone):
Validating instance configuration at *********:3306...
This instance reports its own address as *********
Instance configuration is suitable.
NOTE: Group Replication will communicate with other members using '*********:33061'. Use the local address option to override.
A new instance will be added to the InnoDB cluster. Depending on the amount of
data on the cluster this might take from a few seconds to several hours.
Adding instance to the cluster...
