Error Message

Failed to create %s

🔍

Known Causes

4 known causes

⚠️

Insufficient Directory Permissions

The operating system user running the MariaDB server process lacks the necessary write permissions for the target directory where the filegroup or tablespace file is to be created.

⚠️

Disk Space Exhaustion

The disk partition on which MariaDB is attempting to create the new filegroup or tablespace file has run out of available free space.

⚠️

Invalid or Non-Existent Path

The directory path specified for the filegroup or tablespace does not exist on the filesystem or is incorrectly formatted, preventing MariaDB from locating or creating the required directory.

⚠️

Filesystem Issues

The underlying filesystem where the filegroup is to be created is corrupted, mounted as read-only, or experiencing other critical issues preventing file write operations.

Solutions

3 solutions available

1. Verify Disk Space and Permissions easy

Ensures the MariaDB data directory has sufficient space and correct permissions.

1

Check the available disk space on the partition where your MariaDB data directory resides.

df -h /path/to/your/mariadb/data/directory

2

Verify that the MariaDB user (typically 'mysql') has ownership and write permissions to the data directory and its subdirectories.

ls -ld /path/to/your/mariadb/data/directory
chown -R mysql:mysql /path/to/your/mariadb/data/directory
chmod -R 755 /path/to/your/mariadb/data/directory

3

Restart the MariaDB service to apply any permission changes and re-attempt the operation that caused the error.

sudo systemctl restart mariadb

2. Check MariaDB Configuration for Data Directory Path medium

Confirms the configured data directory path in MariaDB's configuration file is correct and accessible.

1

Locate your MariaDB configuration file (e.g., my.cnf, mariadb.conf.d/50-server.cnf). Common locations include /etc/mysql/, /etc/mariadb/, /etc/my.cnf.

sudo find /etc -name "*mariadb*" -o -name "*mysql*"

2

Open the configuration file and find the 'datadir' parameter within the [mysqld] section. Ensure the path specified is valid and exists.

sudo nano /path/to/your/mariadb/configuration/file

3

If the 'datadir' path is incorrect or points to a non-existent directory, correct it and ensure the new directory exists and has proper ownership/permissions (refer to Solution 1).

[mysqld]
datadir = /new/path/to/mariadb/data

4

Restart the MariaDB service after making any changes.

sudo systemctl restart mariadb

3. Examine MariaDB Error Logs for Detailed Clues medium

Analyzes MariaDB's error logs for more specific reasons behind the filegroup creation failure.

1

Locate your MariaDB error log file. This is often specified by the 'log_error' directive in your MariaDB configuration file.

sudo grep -i 'log_error' /etc/mysql/my.cnf /etc/my.cnf /etc/mariadb/my.cnf /etc/mysql/mariadb.conf.d/*.cnf /etc/mariadb/mariadb.conf.d/*.cnf

2

Open the error log file and search for entries related to 'Filegroup Creation Failure' or the specific file name mentioned in the error message (%s).

sudo tail -f /path/to/your/mariadb/error.log | grep "Filegroup Creation Failure"

3

Look for preceding error messages that might indicate the root cause, such as I/O errors, disk full errors, or issues with specific InnoDB files.

(Review log entries for clues like 'Unable to create file', 'IO error', 'No space left on device', etc.)

4

Based on the error log findings, address the specific issue (e.g., free up disk space, resolve I/O problems, correct filesystem errors).

(Action will vary based on log findings)
