MySQL Error 33: File Seek Operation Failed
Description
MySQL Error 33 signifies that the database server cannot perform a 'seek' operation within a specified file. This typically occurs when MySQL attempts to read from or write to a data file, log file, or temporary file, but is unable to move to a specific byte position within that file. The accompanying operating system error provides more specific details about the underlying problem.
Error Message
Cannot seek in file '%s' (OS errno %d - %s)
Known Causes
4 known causesInsufficient File Permissions
The operating system user account running MySQL lacks the necessary read or write permissions for the file it's attempting to access, preventing seek operations.
Disk Space Exhaustion
The disk partition hosting the MySQL data files, log files, or temporary files is full, preventing the system from extending or modifying files.
File Corruption
The target database file is corrupted or damaged, making it impossible for MySQL to reliably perform seek operations within it.
Network File System (NFS) Issues
If MySQL data files are stored on an NFS share, network latency, misconfiguration, or connectivity problems can interrupt file operations.
