MongoDB Error 13297: Database Case Conflict
Description
Error 13297, 'Database Differ Case', indicates a conflict where MongoDB detects two or more database names that are identical except for their letter casing. This typically occurs on operating systems with case-insensitive file systems, preventing MongoDB from distinguishing between the databases and starting correctly.
Error Message
Database Differ Case
Known Causes
3 known causesCase-Insensitive File System
Operating systems like Windows or macOS (default HFS+) treat database directories with names differing only by case (e.g., 'mydb' and 'MyDb') as the same, causing a conflict for MongoDB.
Manual Data Directory Creation
Manually creating data directories for MongoDB with names that are case-variants of each other on a case-insensitive file system will lead to this error.
Cross-Platform Data Migration
Migrating MongoDB data from a case-sensitive file system (e.g., Linux) to a case-insensitive one (e.g., Windows) can expose pre-existing database name conflicts.
