MySQL Error 10: File Lock Failed
Description
This error indicates MySQL cannot obtain a necessary lock on a file, typically a data file, log file, or index file. This prevents MySQL from performing operations like writing, updating, or even starting, as it cannot secure exclusive access to critical resources.
Error Message
Can't lock file (OS errno %d - %s)
Known Causes
4 known causesInsufficient File Permissions
The MySQL user lacks the necessary read/write permissions for the specific file or its containing directory, preventing the database from acquiring a lock.
File Locked by Another Process
Another application, MySQL instance, or operating system process is currently holding a lock on the required file, preventing MySQL from accessing it.
Read-Only File System
The file system where MySQL is attempting to write is mounted as read-only, making it impossible for MySQL to acquire write locks.
Network File System Issues
Problems with network file systems (NFS, SMB) like disconnections or misconfigurations can prevent proper file locking mechanisms from functioning.
