MariaDB Error 1015: File Locking Failure
Description
Error 1015 indicates that MariaDB was unable to acquire a necessary lock on a file, which is critical for maintaining data integrity and preventing concurrent access issues. This error typically occurs when the database tries to perform an operation requiring exclusive access to a data file, index, or log file, but is prevented from doing so.
Error Message
Can't lock file (errno: %d)
Known Causes
4 known causesIncorrect File Permissions
The MariaDB user lacks the necessary read or write permissions to access or lock the specific file or its parent directory.
Disk Space Exhaustion
The disk partition where the MariaDB data files reside is full, preventing the creation of lock files or modification of existing ones.
Existing File Lock
Another process, application, or even a different MariaDB instance is already holding an exclusive lock on the required file.
Network File System Issues
When MariaDB data is stored on a Network File System (NFS), network latency, misconfiguration, or NFS server problems can disrupt file locking.
