I’m trying to use xtrabackup-v2 in a galera cluster, this is what innobackup.backup.log gives me when a peer tries to join. The host is just an new mariaDB server with only an extra user to give xtrabackup access:
180206 20:26:40 innobackupex: Starting the backup operation
IMPORTANT: Please check that the backup run completes successfully.
At the end of a successful backup run innobackupex
prints “completed OK!”.

InnoDB: Unsupported redo log format. The redo log was created with MariaDB 10.3.4. Please follow the instructions at http://dev.mysql.com/doc/refman/5.7/en/upgrading-downgrading.html
Since everything is a clean install, I have no clue what is going on, the mariadb server on the joiner doesn’t start, I almost started thinking that the packages I use are too new?
