Hi!
I’m running 3 nodes Percona XtraDB Cluster. After I upgrade XtraBackup to 2.4.10, I see at log file:
2018-04-16T00:03:03.580612-03:00 2 [Note] WSREP: You have configured ‘xtrabackup-v2’ state snapshot transfer method which cannot be performed on a running server. Wsrep provider won’t be able to fall back to it if other means of state transfer are unavailable. In that case you will need to restart the server.
What does it means ?
