This topic describes how to manage mount points in the Apsara File Storage NAS console. The management includes creating, deleting, enabling, and disabling mount points. It also includes viewing a list of mount points and modifying the permission group of a mount point.

Create a mount target

To mount a file system on an Elastic Compute Service (ECS) instance, you must add a mount target for the file system. To create a mount target in the NAS console, you can follow these steps.
Note

NAS General-purpose file systems support mount points of the VPC and classic network types. You can create up to two mount points for each file system.

  1. Log on to the NAS console.
  2. Choose File System > File System List.
  3. Find the target file system and choose More > Add Mount Target.
  4. In the Add Mount Point dialog box, configure the required parameters.
    Add a mount target
    Mount Point Type: specifies the network type of mount point. Valid values: VPC and classic network.
    • If you want to create a mount point of the Virtual Private Cloud (VPC) type, configure the parameters that are described in the following table.
      Parameter Description
      VPC Network The VPC where the mount point resides. If no VPC exists, create a VPC in the VPC console.
      Note The VPC and VSwitch that you select must be the same as those of the ECS instance on which you mount a file system. An Elastic Compute Service (ECS) instance and a file system may reside in different VPCs. To enable communication between the ECS instance and the file system, you can use Cloud Enterprise Network (CEN) to connect VPCs. For more information, see Enable a cross-VPC mount for a file system.
      VSwitch The VSwitch that resides in the VPC.
      Permission Group The permission group.

      The VPC default permission group is generated for each Alibaba Cloud account, which allows access to the file system through the mount point from all IP addresses of the VPC. For more information about how to create a permission group, see Create a permission group and add rules.

    • If you want to create a mount point in a classic network, configure the parameter that is described in the following table.
      Parameter Description
      Permission group
      The permission group.
      Note
      • You can add a mount point of the classic network type only in a region that resides in China.
      • You can attach a mount point of the classic network type only to an ECS instance.
  5. After the configuration is complete, click OK.

View a list of mount targets

On the File System List page, find the target file system, and click Manage to open the File System Details page. In the Mount Target section, view a list of mount targets.View a list of mount targets

View a list of clients on which a file system is mounted

To view a list of clients on which a file system is mounted, click Clients. The IP address of each client is also displayed.
Note The list shows clients that have used the file system within the last minute. Some clients that have the file system attached but never used it may be excluded from the list.

Enable or disable a mount target

To control access to the mount target from clients, perform the following operations.
  • To deny access to the mount target from clients, click Disable.
  • To allow access to the mount target from clients, click Enable.

Delete a mount target

To delete a mount target, click Delete.

Warning Use caution when you delete a mount target. After you delete a mount target, the mount target cannot be restored.

Modify the permission group of a mount target

To modify the permission group of a mount target, click Modify Permission Group. For more information about permission groups, see Manage permission groups.
