Manual .frm File Manipulation

Directly copying, moving, or modifying `.frm` files outside of standard SQL DDL commands can corrupt or desynchronize partition metadata.

⚠️

Database Version Mismatch

Restoring a database or table from a different MariaDB version, especially across major versions, can cause partition metadata incompatibility.

⚠️

Corrupted .frm File

Disk errors, unexpected shutdowns, or software bugs can lead to corruption within the `.frm` file, rendering its partition information unreadable or invalid.

⚠️

Incompatible Storage Engine
