Is it possible to add GTID functionality in active and running percona cluster?
Initially claster was setup with gtid_mode=OFF.
Is there some way to activate GTID in this cluster (preferrable online). All my attempts to do so (sequetially switching on gtid_mode to OFF_PERMISSIVE/ON_PERMISSIVE/ON on all cluster nodes) result in different gtid_executed on all cluster nodes (and different GTIDs for same transaction in binlog on different servers).
Maybe someone can provide exact steps to correctly introduce GTIDs in running cluster?
