Galera Cluster generates a GRA log files if it fails to apply the writeset on the target node. This files exists in the MySQL data directory
I use grareader to extract the SQL statement and get distinct statements only.

On every node the /var/lib/mysql/data have different size.
How is the procedure to fix those replication errors? It seems every node have other data, so there are inconsistencies.
Please explain me what is required to get a clean state.
