MySQL Error 1528: File/Resource Creation Failure
Description
MySQL Error 1528, symbolized as `ER_CREATE_FILEGROUP_FAILED`, indicates that the MySQL server was unable to create a necessary file, directory, or filegroup on the underlying file system. This error typically occurs during operations like creating new tablespaces, filegroups, or other storage-related structures, pointing to issues with permissions, disk space, or path configurations.
Error Message
Failed to create %s
Known Causes
4 known causesInsufficient File System Permissions
The MySQL server process lacks the necessary write permissions for the directory where it attempts to create the file or filegroup.
Insufficient Disk Space
The storage volume hosting MySQL's data directory or the specified filegroup path has run out of available disk space.
Invalid Path or Configuration
The file path specified for the filegroup or tablespace in the SQL statement or MySQL configuration (`my.cnf`) is incorrect or does not exist.
Underlying File System Issues
Problems with the underlying file system, such as corruption, full inode tables, or network file system (NFS) issues, prevent file creation.
Solutions
4 solutions available1. Verify File System Permissions easy
Ensure the MySQL user has write permissions to the directory where MySQL is trying to create files.
1
Identify the directory where MySQL is attempting to create files. This is often indicated by the `%s` placeholder in the error message, or you can find it in your MySQL configuration file (my.cnf or my.ini) under `datadir` or `log_error`.
2
Check the ownership and permissions of that directory. The MySQL server process typically runs as a specific user (e.g., `mysql`).
ls -ld /path/to/mysql/data3
Grant write permissions to the MySQL user for the identified directory. Replace `/path/to/mysql/data` with the actual directory path and `mysql` with the correct MySQL user if it differs.
sudo chown -R mysql:mysql /path/to/mysql/data
sudo chmod 755 /path/to/mysql/data4
Restart the MySQL service to apply the permission changes.
sudo systemctl restart mysql2. Check Disk Space easy
Confirm that the file system where MySQL is operating has sufficient free space.
1
Check the available disk space on the partition where your MySQL data directory or log files reside.
df -h2
If disk space is low, free up space by deleting unnecessary files or expanding the disk.
3
After freeing up space, restart the MySQL service.
sudo systemctl restart mysql3. Review MySQL Configuration for File Paths medium
Inspect your MySQL configuration for incorrect or inaccessible file paths.
1
Locate your MySQL configuration file. Common locations include `/etc/my.cnf`, `/etc/mysql/my.cnf`, or `/etc/mysql/mysql.conf.d/mysqld.cnf`.
2
Open the configuration file and examine parameters like `datadir`, `log_error`, `pid-file`, `socket`, and any other paths related to file creation.
grep -E 'datadir|log_error|pid-file|socket' /etc/my.cnf3
Verify that the specified paths exist, are writable by the MySQL user, and do not contain any typos or invalid characters.
4
If any path is incorrect, correct it in the configuration file and restart the MySQL service.
sudo systemctl restart mysql4. Address SELinux or AppArmor Restrictions advanced
If SELinux or AppArmor is enabled, it might be preventing MySQL from creating files.
1
Check the status of SELinux or AppArmor.
sestatus2
If SELinux is enforcing, try temporarily setting it to permissive mode to see if the error resolves. **Note:** This is for testing purposes only and should not be a permanent solution.
sudo setenforce 03
If the error disappears in permissive mode, you'll need to create appropriate SELinux policies to allow MySQL to create files in the required locations. This often involves using `audit2allow`.
sudo grep mysql /var/log/audit/audit.log | audit2allow -M mysql_datadir
sudo semodule -i mysql_datadir.pp4
For AppArmor, check the MySQL profile for any restrictive rules and adjust them accordingly. You might need to edit `/etc/apparmor.d/usr.sbin.mysqld`.
5
Restart the MySQL service after making any SELinux or AppArmor adjustments.
sudo systemctl restart mysql
