MariaDB Error 1039: Unexpected File Read Interruption
Description
Error 1039, 'Unexpected EOF found when reading file', indicates that MariaDB encountered the end of a file sooner than expected during a read operation. This typically means the file is incomplete, truncated, or corrupt, preventing the database from processing it entirely. It often occurs during startup, recovery, or when accessing data files.
Error Message
Unexpected EOF found when reading file '%s' (Errno: %d)
Known Causes
4 known causesIncomplete or Corrupt Data File
Database files (data, index, log) might be truncated or damaged due to a system crash, power failure, or an interrupted write operation, leading to an early end-of-file.
Underlying Storage Corruption
Physical disk errors, bad sectors, or logical filesystem corruption can cause files to appear truncated or unreadable to MariaDB.
Abrupt Server Shutdown
Unplanned server restarts or power outages can interrupt file writes, leaving database files in an inconsistent or incomplete state.
Network Storage Instability
If database files reside on network-attached storage (e.g., NFS), network latency, disconnections, or issues with the storage server can lead to incomplete file reads or corruption.
