Document how to reset gtid_current_pos

    XMLWordPrintable

Details

    Description

      The documentation doesn't currently say how to reset gtid_current_pos:

      https://mariadb.com/kb/en/library/gtid/#gtid_current_pos

      gtid_current_pos is made up by combining GTIDs from two different variables: gtid_binlog_pos and gtid_slave_pos. So to reset gtid_current_pos, you need to reset both of those.

      1.) gtid_binlog_pos can be reset with "RESET MASTER":

      https://mariadb.com/kb/en/library/reset-master/

      https://mariadb.com/kb/en/library/gtid/#gtid_binlog_pos

      2.) gtid_slave_pos can be reset by executing:

      SET GLOBAL gtid_slave_pos='';
