Hi Steph,

First point, you should not run GR with only two nodes as this won't tolerate any failure. Indeed if one node dies, the other one won't have more then 50% for quorum and will stop to avoid split-brain.

It also seems that you run more writes on the second node. Are you running some statements with set sql_log_bin=0 ? or do you run the server without log_slave_updates ?

Regards,

lefred.
