Blacklisted Directory

A blacklisted directory is a group of directories that are explicitly prohibited from being mounted or accessed in a specific system or application. These directories usually contain key system files, configuration files, or platform-specific data, which are critical to the normal operation of the system and service functions.

Do not mount the following blacklisted directories. Otherwise, the instance may fail to start or service functions may be abnormal.

Blacklisted directories include key system directories, ModelArts reserved directories, and user home directories.

• Key system directories: These directories are essential for the proper functioning of the operating system. Mounting to these directories may cause the system to fail to start or service functions to become abnormal.
  • /dev/: Device file system
  • /etc/: System configuration files
  • /bin/: Executable files of basic commands
  • /lib/: Basic library files
  • /sbin/: System management commands
  • /var/: Variable data files
  • /usr/: User programs and files
  • /sys/: Kernel and device information
  • /run/: Runtime data
  • /opt/: Optional applications
  • /tmp/: Temporary files
• ModelArts reserved directories: These directories are specific to the ModelArts platform and are used to store temporary files, model data, logs, and more. Mounting to these directories may cause platform function exceptions.
  • /cache/: Local disk directory mounted for file acceleration. It is cleared after the instance is stopped.
  • /modelarts/: ModelArts-related files
  • /data/: Dynamic storage directory mounted to the development environment
  • /train-worker1-log/: Training logs
  • /resource_info/: Resource information
  • /infer/: Inference files
  • /home/ma-user/work/: Working directory of a notebook instance
• User home directory: Home directory of a user who started the system. Mounting to these directories may overwrite user configuration files, keys, or environment variables, causing user environment exceptions or service function unavailability.

  Example:

  • /root/: Home directory of the root user
  • /home/ma-user/: Home directory of the ma-user user
