I have a single node percona XtraDB Cluster.
Version: Server version: 5.6.15-56 Percona XtraDB Cluster (GPL), Release 25.5, Revision 759, wsrep_25.5.r4061
All tables in the DB are using InnoDB engine and the database is partitioned.
The server is a RHEL 6 server and I want to upgrade it to RHEL 7. What I am planning to do is, stop mysql on the old server, shut it down, disconnect the disk (old and new servers are VMs), connect it to the new RHEL 7 server, turn the new server on, mount the disk, change mysql configuration so that it will point to the new filesystem. Sounds good on paper but will this actually work?
