MariaDB Error 1809: Table in System Tablespace
Description
MariaDB Error 1809, 'Table '%s' in system tablespace', indicates an attempt to perform an operation (such as DROP TABLE, ALTER TABLE, or RENAME TABLE) on a table that resides within the shared system tablespace (e.g., `ibdata1` for InnoDB). This error occurs because MariaDB restricts direct manipulation of tables located in the system tablespace to maintain data integrity and system stability.
Error Message
Table '%s' in system tablespace
Known Causes
3 known causesModifying Internal System Tables
This error occurs when an operation is attempted on a table that is an internal component of the MariaDB system or data dictionary, which are typically stored in the system tablespace.
User Table in System Tablespace
A user-defined table might have been inadvertently created or moved into the shared system tablespace instead of its own file-per-table tablespace, making it subject to system tablespace restrictions.
Incorrect `innodb_file_per_table` Configuration
If `innodb_file_per_table` was disabled when the table was created, its data and index pages would reside in the shared system tablespace, leading to this error when attempting to manage it.
