MariaDB Error 1018: Directory Access Issues
Description
MariaDB Error 1018 indicates that the server process attempted to read a directory but failed. This typically occurs when MariaDB lacks the necessary permissions to access a specified directory, the directory itself is missing or corrupted, or there's an underlying filesystem problem.
Error Message
Can't read dir of '%s' (errno: %d)
Known Causes
4 known causesInsufficient Directory Permissions
The MariaDB server process (often running as 'mysql' user) lacks the necessary read and execute permissions for the specified data directory, log directory, or temporary file path.
Missing or Incorrect Directory Path
The directory MariaDB is attempting to access either does not exist on the filesystem or the path specified in the configuration (e.g., `datadir`, `tmpdir`) is incorrect.
Underlying Filesystem Problems
Issues such as a corrupted filesystem, a full disk, an unresponsive network mount, or other operating system-level problems can prevent MariaDB from reading directories.
OS Security Module Restrictions
Security mechanisms like SELinux or AppArmor might be configured to deny MariaDB access to certain directories, even if standard file permissions appear correct.
