To access a CPFS for Lingjun file system from PAI general-purpose computing resources or ACS pods that do not support RDMA, you must add a VPC mount target. Lingjun resources and ACS GPU pods that support RDMA connect directly to CPFS over an RDMA network and do not require a VPC mount target.
Use cases
Scenario | VPC mount target required | Notes |
PAI general-purpose computing resources | Required | Public resource pools, general-purpose ECS instances |
PAI Lingjun resources | Not required | Connects directly to CPFS over the RDMA network. |
ACS GPU pods (RDMA not supported) | Required | T4/A10/L20/G49E/G59 |
ACS GPU pods (RDMA supported) | Not required | GU8TF/GU8TEF/L20X/P16EN |
ACS CPU pods | Required | - |
If you use Lingjun resources or RDMA-capable GPUs, you can skip this topic and go directly to Mount a CPFS for Lingjun file system on PAI or Mount a CPFS for Lingjun file system on ACS.
With CPFS for Lingjun, both Lingjun resources and general-purpose computing resources can mount the file system and share its storage performance. To improve the performance of VPC mount targets, submit a ticket to request an evaluation.
Add a VPC mount target
Prerequisites: You have created a CPFS for Lingjun file system of version 2.5.0 or later. You can view the version number on the Basic Information page.
Log on to the CPFS console.
In the left-side navigation pane, choose File system > File system list.
In the top navigation bar, select a region.
Find the target file system and click Add mount target in the Actions column.
In the Add Mount Target dialog box, configure the following parameters:
Parameter
Description
VPC network
Select the VPC where your computing resources are located. The VPC must be the same as the one used by your PAI general-purpose computing resources. Cross-VPC access is not supported. If you have not created a VPC, create a VPC.
vSwitch
Selecting a vSwitch in the same availability zone as your computing resources reduces network latency.
Click OK.
View the mount target domain name
In the file system list, click the name of the target file system.
Click the Mount targets tab.
In the mount target list, hover over the
icon in the Mount target column to view and copy the mount target domain name.
View the list of mounted clients
Troubleshoot mounting issues or view which computing resources are using this mount target.
This list shows only PAI general-purpose computing resources that have actively used the CPFS for Lingjun file system in the last minute. Resources that have the file system mounted but are not active may not appear.
Log on to the CPFS console.
In the left-side navigation pane, choose File system > File system list.
Click the target file system to go to its details page.
Click the Mount targets tab.
In the mount target list, click Client list in the Actions column.
View the IP addresses of the computing resources that have mounted the file system.
Delete a mount target
This operation cannot be undone. Proceed with caution. Before you delete a mount target, ensure that no tasks or instances are using it. Otherwise, file system access will fail.
In the mount target list, click Delete in the Actions column.
In the confirmation dialog box, click OK.
Next steps
After you configure the VPC mount target, mount the file system on your platform:
