Hi @iconvnet_iconvnet

Could you share used my.cnf file on the second node?

Please ensure both your joiner and donor nodes have the “Percona XtraBackup 8.0.33-27” installed.

Hello @iconvnet_iconvnet,

You have not given much information. You did not tell us the OS, or share the my.cnf file. Do you have SELinux enabled? Have you opened all the proper ports between nodes? Have you tested connectivity using telent, or socat? What do the logs on the donor node say?

At the beginning, xtrabackup version 8.0.35-33 was installed, but synchronization failed. Later, I changed the version of the second node to xtrabackup version 8.0.33-28, but it still failed

Before PXC 8.0.34, it was required to use matching versions of both the database and `xtrabackup`. Please ensure that all nodes in the cluster are running the same versions of MySQL and `xtrabackup`.

If the issue persists, review the `innobackupex` log on the donor node to verify whether the backup process starts correctly, and if it fails, check for the specific error message reported.
