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.

```auto
Starting Percona XtraDB Cluster...
mysql.service: Main process exited, code=killed, status=6/ABRT
mysql-systemd[946119]: WARNING: mysql pid file /var/run/mysqld/mysqld.pid empty or not readable
mysql-systemd[946119]: WARNING: mysql may be already dead
systemd[1]: mysql.service: Failed with result 'signal'.
systemd[1]: Failed to start Percona XtraDB Cluster.

```

In the error log on node2 I am getting

```auto

```

How can I check the PXC version?

Hi Danarashad,

The error is:

> [ERROR] [MY-000000] [WSREP-SST] This node’s PXC version is 8.0.25. The donor’s PXC version is 8.0.26.

Try upgrading the joiner node to match the same version as the donor.

Regards
