Bugs Fixed¶
#1494399: Fixed issue caused by replication of events on certain system tables (for example,
mysql.slave_master_info
,mysql.slave_relay_log_info
). Replication in the Galera eco-system is now avoided when bin-logging is disabled for said tables.Note
As part of this fix, when bin-logging is enabled, replication in the Galera eco-system will happen only if
BINLOG_FORMAT
is set to eitherROW
orSTATEMENT
. The recommended format isROW
, whileSTATEMENT
is required only for thept-table-checksum
tool to operate correctly. IfBINLOG_FORMAT
is set toMIXED
, replication of events in the Galera eco-system tables will not happen even with bin-logging enabled for those tables.#1522385: Fixed GTID holes caused by skipped replication. A slave might ignore an event replicated from master, if the same event has already been executed on the slave. Such events are now propagated in the form of special GTID events to maintain consistency.
#1532857: The installer now creates a
/var/lib/galera/
directory (assigned to usernobody
), which can be used bygarbd
in the event it is started from a directory thatgarbd
cannot write to.
Known Issues¶
- #1531842: Two instances of
garbd
cannot be started from the same working directory. This happens because each instance creates a state file (gvwstate.dat
) in the current working directory by default. Althoughgarbd
is configured to use thebase_dir
variable, it was not registered due to a bug. Untilgarbd
is fixed, you should start each instance from a separate working directory.
