Running galera on 3 nodes(two nodes + garb).
SST method: xtrabackup-v2
Garb and the master node was already running well.
When I was trying to add the third node, every time it fails with the following errors:
I can see that xtrabackup finished correctly and db files were copied over. And there's no error in innobackup.backup.log on the donor.
I also monitored the processes while the SST was in progress and I noticed that mysqld already exited while SST is running.
