The server cannot complete a keyring migration, blocking startup or encryption operations.
MySQL error 3201 ER_KEYRING_MIGRATION_FAILURE occurs when the server fails to migrate keys between keyring plugins during startup or ALTER INSTANCE ROTATE INNODB MASTER KEY. Verify plugin availability, paths, and privileges, then rerun the migration to resolve the issue.
ER_KEYRING_MIGRATION_FAILURE
Error 3201 appears when MySQL tries to copy existing encryption keys from the current keyring plugin to a new plugin but encounters a fatal problem. The server aborts the migration and reports ER_KEYRING_MIGRATION_FAILURE.
This error can surface on server startup, during ALTER INSTANCE ROTATE INNODB MASTER KEY, or when the mysql_keyring_migration utility runs. Until fixed, the server cannot access encrypted data or complete startup in some configurations.
Missing destination plugin files, incorrect plugin_dir, or an uninstalled keyring plugin stops the migration process. The server cannot load the target keyring and raises the failure.
Wrong file permissions on the source or destination keyring files also trigger the error. The server process user must have read access to the old keys and write access to the new location.
Mismatched keyring formats or unsupported key types prevent the migration utility from serializing keys, resulting in error 3201.
First, confirm that both the source and destination keyring plugins are installed and listed in the mysql.plugin table. Use SHOW PLUGINS to verify status.
Next, check the --early-plugin-load or plugin-load-add options in my.cnf to ensure the correct shared libraries are referenced. Correct the path if necessary.
If file permissions cause the issue, adjust ownership so the MySQL OS user can read the existing keyring file and write the new one. Then rerun the migration:
ALTER INSTANCE ROTATE INNODB MASTER KEY;
Upgrading from the keyring_file plugin to keyring_encrypted_file often triggers this error when the new plugin path is wrong. Verify plugin_dir and file path.
When migrating to keyring_hashicorp or keyring_aws, network or credential issues can prevent key storage, causing the migration to fail. Test connectivity with the provider CLI first.
Always stage plugin files in plugin_dir before enabling a new keyring. Test loading with INSTALL PLUGIN before running a full migration.
Back up current keyring data and my.cnf. Use mysql_keyring_migration with --dry-run to validate paths and permissions prior to actual migration.
ER_KEYRING_ACCESS_ERROR - Raised when the keyring file itself is unreadable. Fix by adjusting file permissions.
ER_KEYRING_UDF_KEYRING_SERVICE_ERROR - Occurs when UDFs cannot access keyring services. Ensure UDF has proper linkage and plugin is loaded.
The shared library for the destination keyring plugin is absent from plugin_dir, so MySQL cannot load it.
The plugin-load directive references an invalid path, preventing the destination plugin from initializing.
The MySQL service account lacks read or write rights on source or destination keyring files.
Keys stored by the source plugin are incompatible with the destination plugin's serialization logic.
Raised when MySQL cannot read the keyring file - usually permission related.
Occurs when UDF interactions with keyring services fail - check plugin load order.
Signals that the keyring plugin failed during initialization - inspect server error log for specifics.
If migration runs during early startup, the server may halt. Review the error log to confirm.
Yes. Revert my.cnf to the original plugin-load line, restore the old keyring file, and restart MySQL.
Encrypted InnoDB tablespaces remain unreadable without successful keyring access, so resolve promptly.
