Hi!,
I am running an 5 Head Percona XtraDB-Cluster 5.5.39-36.0-55-log.
Xtrabackup Version installed is
percona-xtrabackup-2.2.8
I found in my logs that the xtrabackup is starting a wrong version of innodb:
xtrabackup version 2.2.8 based on MySQL server 5.6.22
I remember that it is important to use the “right” binary of xtrabackup for the Server. In the xtrabackup version percona-xtrabackup-2.1.9 where 3 binarys and the log said:
xtrabackup_55 version 2.1.9 for Percona Server 5.5.35
I am a little bit concerned that the 5.6 innodb is possibly writing unreadable datafiles for 5.5 innodb.
Can somebody explain this to me?
