Description
Hello
We have hit an issue where a new cluster member will drop from the cluster with a consistency error as soon as mysql asynchronous replication is started on the donor node.
Another user has hit almost exactly the same problem and documented it here. The difference in our use case is the replication master (Percona XtraDB Cluster 5.7.27) rather than MySQL5.6 and our voting outcome is slightly different:

We can't go into production with MariaDB until this is resolved.
Thanks
