Hi Guys, I am running MySQL cluster of 3 nodes using percona XtraDB cluster. It is running fine since very long. But now I need to expand the cluster by adding one more node to it. But while adding the node I am getting the below error:-

WSREP_SST: [ERROR] Cleanup after exit with status:1 (2023-03-27 09:48:52)
2023-03-27 09:48:52 9364 [ERROR] WSREP: Process completed with error: wsrep_sst_xtrabackup-v2 --role ‘joiner’ --address ‘10.51.53.111’ --datadir ‘/var/lib/mysql/’ --defaults-file ‘/etc/mysql/my.cnf’ --defaults-group-suffix ‘’ --parent ‘9364’ --mysqld-version ‘5.6.51-91.0-56’ --binlog ‘mysql-bin’ : 1 (Operation not permitted)

This is 5.6? This version has been dead and unsupported for 4+ years. Make sure you have xtrabackup 2.4 installed on the new node before starting MySQL.
