MySQL Error 1812: Tablespace Missing
Description
This error indicates that MySQL cannot locate the expected tablespace file(s) associated with a specific table. It typically occurs when MySQL attempts to access or operate on a table whose physical data files (like .ibd for InnoDB) are no longer present or accessible at their registered location.
Error Message
Tablespace is missing for table %s.
Known Causes
4 known causesManual File Manipulation
The physical .ibd file or other tablespace components for the table were manually deleted, moved, or renamed outside of MySQL's control.
Data Directory Issues
The MySQL data directory or the specific subdirectory containing the tablespace files became corrupted, inaccessible, or was lost due to disk failure or misconfiguration.
Incomplete Restore/Migration
During a database restore or migration, the tablespace files were not correctly copied or restored to their expected locations, leading to a mismatch with MySQL's internal dictionary.
Configuration Mismatch
The MySQL server configuration (`datadir` or `innodb_data_home_dir`) points to a location where the required tablespace files are not present or accessible.
