Hi,

If it takes you a few seconds, that is okay.  It is not likely that the cluster will require a SST in that brief period.  You can also simply use a parallel SSH tool to execute the following on all nodes at the same time: mysql -uroot -ppassword -e 'set global wsrep_sst_method=xtrabackup'

Hi Nirbhay,
thank you very much for your answer.
This cluster is already in production, with few databases (for mail user authentication, radius authentication, and so on).
My question is:  what would will happen if I change wsrep_sst_method on one node?
How the other node can be "synced" if wsrep_sst_method is different (even for a few seconds)?

Thank you, regards
