Today, i have small cluster using mariadb Cluster
2 servers in one DC in one country
and other 2 servers in other Dc in other country,
sometimes when one of us fails, I do not know why, it's knocking down all the other nodes
Today i use rsyncmode, i try migrate for xtrabackup, and it does not work, it somehow corrupts the database.
need help, to optimize my cluster, I can not have unavailability
