Failed to create %s
MySQL raises error 1528 ER_CREATE_FILEGROUP_FAILED with message Failed to create %s when the server cannot create a new filegroup or tablespace on disk. The placeholder %s is replaced by the object name that failed.
The failure stops statements such as CREATE TABLESPACE, CREATE LOGFILE GROUP, or ALTER TABLE ... TABLESPACE and signals an underlying storage or configuration problem.
The error appears while provisioning InnoDB general tablespaces, NDB Cluster logfile groups, or moving tables to a different tablespace.
It also surfaces during server start if the engine attempts to recreate missing shared tablespace files.
Blocking table or tablespace creation halts schema migrations, causes application downtime, and may leave orphaned metadata. Immediate resolution restores normal DDL operations and guards data consistency.
Disk volumes without free space stop MySQL from writing .ibd, .ibdata, or .ndb files.
The mysqld process lacks write permission on the target directory path.
The path is read only, does not exist, or is blocked by SELinux or AppArmor.
A filegroup or tablespace of the same name already exists, causing a name collision.
Incorrect innodb_data_home_dir or ndb_data_home_dir point to invalid locations.
Check available disk space and expand the filesystem or clear unused files.
Grant the mysqld user write access to the directory defined in the CREATE TABLESPACE statement.
Verify the directory exists, is mounted read write, and has correct SELinux context.
Run DROP TABLESPACE or DROP LOGFILE GROUP to remove conflicting metadata, then recreate.
Review my.cnf settings for innodb_data_home_dir, innodb_directories, or ndb data directories and correct invalid paths.
Scenario: Creating a general tablespace on a full partition. Solution: Allocate more space or move the tablespace to a larger volume, then retry.
Scenario: Recreating an NDB logfile group after crash. Solution: DROP LOGFILE GROUP group_name ENGINE NDB; confirm removal, then issue the CREATE statement again.
Scenario: SELinux blocking writes. Solution: Run chcon and semanage fcontext to allow mysqld_t access, or set SELINUX permissive temporarily for testing.
Monitor disk usage and maintain at least 20 percent free space on data volumes.
Store all tablespaces in directories owned by mysqld with 750 permissions.
Adopt naming conventions and version control for tablespace DDL to avoid collisions.
Validate configuration on staging before applying to production clusters.
Error 1005 Can't create table ... errno: 150 arises from foreign key issues; review constraint definitions.
Error 1044 Access denied for user indicates privilege problems; grant CREATE TABLESPACE rights.
Error 1813 Tablespace ... is missing occurs when tablespace files are deleted; restore or recreate them.
Lack of free blocks prevents creation of new .ibd or .ibdata files, immediately triggering error 1528.
The mysqld user cannot write to the specified directory due to ownership or mode settings.
The target directory is read only, unmounted, or mistyped, so MySQL fails when opening the file.
A tablespace or logfile group with the same name already exists in the data dictionary.
my.cnf variables point to invalid or inaccessible paths, blocking filegroup creation.
Foreign key mismatch blocks table creation. Review constraint definitions.
User lacks CREATE TABLESPACE or FILE privilege. Grant or adjust roles.
Tablespace file was removed manually. Restore from backup or DROP and recreate the tablespace.
General filesystem or quota problem blocks database creation, similar root cause to error 1528.
No. The failed tablespace creation leaves the table unusable until the error is resolved or the statement is rolled back.
The error blocks new file creation but does not corrupt existing tables. However, incomplete DDL may leave orphaned metadata.
Enable general log or check the server error log; MySQL logs the full pathname that failed.
Yes. Galaxy's SQL editor surfaces server error logs in real time, letting engineers spot disk or permission problems instantly and fix DDL scripts before rerunning.
