Mount CFS File System When Purchasing New BCC

Updated at：2025-11-11

This document explains how to mount a CFS file system while purchasing a BCC.

Prerequisites

  • The file system has been created. For details, refer to: Create File System.
  • Add a mount target. For specific operations, please refer to Add Mount Target.

Usage restrictions

Currently, the following restrictions apply for configuration for mounting CFS file systems to newly purchased BCC instances:

  1. Mount directory: Only the root directory of the CFS file system is supported; subdirectories cannot be mounted.

  2. Mount count: Support mounting up to 5 CFS file systems

    Note: If the current BCC configuration for mounting CFS file systems cannot meet service needs, manually mount the CFS file system after BCC creation. For specific operations, please refer to: Mounting and Unmounting NFS CFS for a Single BCC , Batch Mounting and Unmounting NFS CFS for Multiple BCCs , Mounting and Unmounting SMB CFS for a Single BCC , Mounting and Unmounting SMB CFS for Windows Systems .

Mount an CFS file system

  1. Sign in to the Baidu Cloud Compute (BCC) console.
  2. Create a BCC instance. For steps, refer to Creating an Instance in the Purchase Page.
  • Add the cloud file system through the storage module on the custom purchase page.

File system
  • Linux systems only support file systems with NFS.
  • Windows systems support only file systems with SMB.
    		•
    Domain name of a mount target
  • For network connectivity between CFS and BCC, it requires that BCC belongs to the same private network VPC as CFS.
  • If no options are available, add a mount target for the current file system. For specific steps, refer to Add Mount Target.
    		•
    Mount directory/drive letter Access the CFS local path or drive letter from the BCC. For instance, use /mnt/cfs for Linux systems and z for Windows systems.
    Protocol type
  • For NFS file systems, simply select NFSv4.1
  • For SMB file systems, just select SMB.
    		•

    Verify mount results

    Linux system

    1. Sign in to the Baidu Cloud Compute (BCC) where the CFS file system is mounted.
    2. Check if the mount is successful using the following command:
    Shell 
    1df -h

    If the following information is returned, it indicates the mount is successful

    1. Once mounted successfully, the CFS file system can be accessed and used like a regular local directory on the BCC.

    Windows system

    1. Sign in to the Baidu Cloud Compute (BCC) where the CFS file system is mounted.
    2. Use the following commands in the Windows Command Line or PowerShell to view mounted file systems.
    Shell 
    1net use

    Alternatively, you can open Windows Explorer to check the drive letters in the network locations.
