I have 5 Node in Galera cluster. MariaDB Server 10.1.21-MariaDB-1~trusty.
I will remove 2 nodes from it but one of them will be a slave. So from 5 nodes 5th one will be completely removed, 4th one will be a slave of 3rd one.
I don't want to rebuild a backup from 3rd one. I just wanted to make 4th out of cluster and become slave of 3rd one.
May I know the procedure for it?
Also why is gtid_current_pos is changing for one node and not on other nodes?
Let me know if you need any clarifications.
