I started a new cluster, I got 2 nodes on the cluster. To test the joining and replication process I stopped node 2 (stopped the service) added data to node 1. On restart of node 2 I am getting a failure.
In the system log on node2 I am getting.
Starting Percona XtraDB Cluster... mysql.service: Main process exited, code=killed, status=6/ABRT mysql-systemd: WARNING: mysql pid file /var/run/mysqld/mysqld.pid empty or not readable mysql-systemd: WARNING: mysql may be already dead systemd: mysql.service: Failed with result 'signal'. systemd: Failed to start Percona XtraDB Cluster.
In the error log on node2 I am getting

How can I check the PXC version?
