MySQL Error 3678: Schema Directory Exists
Description
This error occurs when MySQL attempts to create a new database schema, but a directory with the intended schema name already exists in the MySQL data directory. This typically prevents the `CREATE DATABASE` operation from completing successfully.
Error Message
Schema directory '%s' already exists. This must be resolved manually (e.g. by moving the schema directory to another location).
Known Causes
3 known causesDatabase Creation Conflict
A `CREATE DATABASE` statement was executed for a database name that already has a corresponding directory on the filesystem.
Incomplete Database Deletion
A previous `DROP DATABASE` operation failed or was interrupted, leaving the database's data directory intact.
Manual Directory Interference
A directory matching a database name was manually created or moved into the MySQL data directory, conflicting with a subsequent `CREATE DATABASE` command.
