    Description

      WSREP GTID MODE is inconsistent

      When you create a Galera cluster with the following configuration according to documentation:

      # NODE 1 (m1)
      		 
      wsrep_gtid_mode=ON
      		 
      wsrep_gtid_domain_id=1111
      		 
      gtid_domain_id=2
      		 
      server_id=10999
      		 
      log_slave_updates=ON
      		 
      log_bin = /var/log/mysql/mariadb-bin-log
      		 
       
      		 
      # NODE 2 (m2)
      		 
      wsrep_gtid_mode=ON
      		 
      wsrep_gtid_domain_id=1111
      		 
      gtid_domain_id=3
      		 
      server_id=10999
      		 
      log_slave_updates=ON
      		 
      log_bin = /var/log/mysql/mariadb-bin-log
      		 
       
      		 
      # NODE 3 (m3)
      		 
      wsrep_gtid_mode=ON
      		 
      wsrep_gtid_domain_id=1111
      		 
      gtid_domain_id=4
      		 
      server_id=10999
      		 
      log_slave_updates=ON
      		 
      log_bin = /var/log/mysql/mariadb-bin-log

      Sometimes, the nodes will stay in sync. However, if the following is done:
      1) transactions run on all three nodes
      2) restart mariadb on any node
      3) restart all three nodes, using galera_new_cluster on a different node from first startup

      Then, GTIDs will become inconsistent both at the domain level and at the seq_no level.

      This is not difficult to reproduce.
