MongoDB Error 37: File Rename Failed
Description
This error indicates that MongoDB was unable to rename a file, often a data file, journal file, or temporary file. This typically occurs during database operations such as startup, shutdown, data compaction, or recovery, preventing the server from proceeding.
Error Message
File Rename Failed
Known Causes
4 known causesInsufficient File Permissions
The MongoDB user account lacks the necessary read and write permissions for the data directory or specific files involved in the rename operation.
File Locked by Another Process
Another application, such as an antivirus scanner, backup utility, or a stray MongoDB process, is holding a lock on the file MongoDB is attempting to rename.
Insufficient Disk Space
Although renaming itself is a metadata operation, underlying operations requiring temporary files or new file creation (which are then renamed) can fail if the disk is full.
Filesystem Corruption or Errors
Underlying issues with the host's filesystem, such as bad blocks or corruption, can prevent file system operations like renaming.
