MySQL Error 3831: Unknown Tablespace Type
Description
This error indicates that MySQL cannot identify the internal type or format of a specified tablespace. This often occurs when the database attempts to access or create a tablespace whose metadata is missing, corrupted, or incorrectly defined, making it unreadable by the server.
Error Message
Cannot determine the type of the tablespace named '%s'.
Known Causes
4 known causesCorrupted Tablespace Files
The physical tablespace file on disk may be corrupted or partially overwritten, preventing MySQL from reading its header and determining its type.
Incorrect Tablespace Definition
The tablespace was created with an invalid or unsupported internal structure, or its definition in the data dictionary is inconsistent with the actual file.
Filesystem or Disk Issues
Underlying filesystem errors, disk failures, or insufficient permissions can prevent MySQL from properly accessing and interpreting the tablespace files.
Incomplete Recovery or Migration
The tablespace might have been restored or migrated incorrectly, leading to a state where its type cannot be reliably determined by the MySQL server.
