I have a MariaDB Galera cluster with 3 nodes and I configured the SST transfer as
wsrep_sst_method = rsync
When I have to stop and restart a single node, the synchronization is very slow even if the node remained stopped only for 1 hour: it takes about 2 hours to sync.
Is there a way to speed up the synchronization time?
Thanks!
You could change SST method to
xtrabackup-v2
(here simple documentation) and configure MySQL as described in this article in Percona blog. May be it could be helpful for you.
