MySQL Error 3091: GTID-Enabled Drop Inconsistency
Description
This error indicates that a DROP DATABASE command failed to complete successfully in a MySQL server configured with Global Transaction Identifiers (GTID). While some tables might have been dropped, the database directory persists, and crucial GTID information for the operation was not recorded, leading to an inconsistent state in the binary log and potential replication issues.
Error Message
DROP DATABASE failed; some tables may have been dropped but the database directory remains. The GTID has not been added to GTID_EXECUTED and the statement was not written to the binary log. Fix this as follows: (1) remove all files from the database directory %s; (2) SET GTID_NEXT='%s'; (3) DROP DATABASE `%s`.
Known Causes
3 known causesIncomplete Database Drop
The DROP DATABASE operation encountered an issue mid-execution, preventing its atomic completion and leaving behind the database directory.
GTID Logging Failure
The MySQL server failed to correctly log the Global Transaction Identifier (GTID) for the DROP DATABASE statement, resulting in its absence from GTID_EXECUTED and the binary log.
Concurrency or Resource Issues
Active connections, concurrent operations, or temporary resource constraints (e.g., disk I/O) might interfere with the complete removal of the database directory and its contents.
