MySQL Error 4071: GTID_ONLY Requires GTID_MODE ON

📋

Description

This error occurs when a MySQL replica server attempts to start replication with the `GTID_ONLY = 1` option, but its global `GTID_MODE` system variable is not set to `ON`. For `GTID_ONLY` to function, the server must be configured to operate in full GTID mode to process transactions reliably.

💬

Error Message

Replication cannot start with GTID_ONLY = 1 as this server uses @@GLOBAL.GTID_MODE <> ON.

Known Causes

3 known causes

⚠️

Replica's GTID_MODE Not ON

The `@@GLOBAL.GTID_MODE` system variable on the replica server is not set to `ON`, which is a prerequisite for enabling `GTID_ONLY = 1` for replication.

⚠️

Accidental GTID_ONLY Activation

The `GTID_ONLY = 1` option was inadvertently included or misconfigured in the `CHANGE REPLICATION SOURCE TO` (or `CHANGE MASTER TO`) statement without ensuring the server's GTID mode was correctly set.

⚠️

GTID Configuration Mismatch

There's a discrepancy between the intended GTID-based replication setup and the actual `GTID_MODE` configuration on the replica server, preventing `GTID_ONLY` from being used.
