MySQL Error 3868: Clone Configuration Mismatch
Description
This error indicates a mismatch in critical configuration parameters between the donor and recipient MySQL instances during a cloning operation using the MySQL Clone Plugin. It occurs when a recipient instance attempts to clone data, but a specified configuration value on the donor differs from the corresponding value on the recipient, preventing the clone from proceeding successfully.
Error Message
Clone Configuration %s: Donor value: %s is different from Recipient value: %s.
Known Causes
4 known causesConflicting Server ID
The 'server_id' configured on the recipient MySQL instance is identical to the donor instance's 'server_id', which is not allowed for a successful cloning operation.
Mismatched Data Directory
The 'datadir' setting on the recipient instance is either identical to or conflicts with the donor's data directory, preventing the clone from proceeding safely.
Incompatible GTID Configuration
The Global Transaction Identifiers (GTID) configuration (e.g., 'gtid_mode') differs between the donor and recipient, which can prevent the cloning operation.
Other Vital Configuration Discrepancies
Other critical MySQL server configuration parameters might have conflicting values between the donor and recipient, causing the clone operation to fail.
