Hi,
I am using two nodes (Debian 7.8 64bit) with MariaDB (mariadb-galera-server 5.5.41) and garbd on a third node.

Now I'm using rsync method, I would like to switch to xtrabackup to avoid "lock" issue.
Is it possible?

Should I simply install percona package and change this configuration?

wsrep_sst_method=rsync

to

wsrep_sst_method=xtrabackup

?
Thank you very much
