Hi,
thank you for your reply.
What is the correct order for this step?
For example:

1) shutdown node 1
2) change config to xtrabackup-v2 on node 1
3)  restart node 1?
4) shutdown node 2
5) change config to xtrabackup-v2 on node 2
6) restart node 2

..and what about garbd on the third node? :)

Thank you very much

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?

Yes, the lock is taken only for syncing system tables.
 

Should I simply install percona package and change this configuration?

Right, the package name is "percona-xtrabackup".
 

wsrep_sst_method=rsync

to 

wsrep_sst_method=xtrabackup

?
Or rather go for "xtrabackup-v2".

SST methods other than "rsync" also require "wsrep_sst_auth" variables to be set.

Thank you very much
