Cloud Parallel File Storage:Manage VPC mount targets

Prerequisites

A CPFS for Lingjun file system is created. For more information, see Create a file system.

Usage notes

• You need to add a VPC mount target only if you use CPFS for Lingjun with general computing resources. You do not need to add a VPC mount target if you use CPFS for Lingjun with Lingjun resources.

• You can add VPC mount targets only for CPFS for Lingjun file systems whose versions are V2.5.0 and later.

• VPC mount targets only support mounting by PAI general computing resources and ACS CPU pods. They do not support mounting and access by ECS or Elastic GPU Service (EGS) instances directly created by customers.

• CPFS for Lingjun supports simultaneous mounting by both Lingjun resources and general computing resources, sharing storage performance. If you need to improve VPC mounting performance, submit a ticket to request an evaluation.

Add a VPC mount target

1. Log on to the File Storage NAS (NAS) console.

2. In the left-side navigation pane, choose File System > File System List.

3. In the top navigation bar, select a region.

4. Find the file system that you want to manage and click Add Mount Target in the Actions column.

5. In the Add Mount Target dialog box, configure the following parameters.

   Parameter	Description
   VPC Network	The VPC in which you want to create the mount target. If no VPC is available, create a VPC in the VPC console. You must select the VPC in which the general PAI computing resources reside. Otherwise, you cannot use the mount target to access the CPFS for Lingjun file system.
   vSwitch	The vSwitch that resides in the VPC.

6. Click OK.

View the domain name of a mount target

1. Log on to the NAS console.

2. In the left-side navigation pane, choose File System > File System List.

3. In the top navigation bar, select a region.

4. Click the ID of the file system that you want to view to go to the details page of the file system.

5. In the left-side pane, click Mount Targets. In the Mount Target section, move the pointer over the icon in the Mount Target column of a mount target, and you can view the domain name of the mount target.

View the clients on which a file system is mounted

You can view the IP addresses of general PAI computing resources on which a CPFS for Lingjun file system is mounted.

1. Log on to the NAS console.

2. In the left-side navigation pane, choose File System > File System List.

3. In the top navigation bar, select a region.

4. Click the ID of the file system that you want to view to go to the details page of the file system.

5. In the left-side bar, click Mount Targets. In the mount target list, click Client List in the Actions column of a mount target. In the Client List dialog box, you can view the IP addresses of the general PAI computing resources on which the CPFS for Lingjun file system is mounted.

   You can also click View to access the instance page in the ECS console to view the details of the target client.

Delete a mount target

In the Mount Target section, find the mount target that you want to delete and click Delete in the Actions column.

What to do next

After adding a mount target, you must create a dataset in the PAI console and select this dataset when you create an AI development task. For more information, see Create and manage datasets.
