Cloud Parallel File Storage:Create a file system

Last Updated:Mar 06, 2026

Create a CPFS for Lingjun file system to provide ultra-high-performance parallel storage with end-to-end RDMA networking for AI workloads such as AIGC and autonomous driving.

Prerequisites

Before you begin, ensure that you have:

  • Activated CPFS service.

    On first login to the File Storage NAS (NAS) console, activate CPFS as prompted.

  • A whitelisted account for CPFS for Lingjun.

    CPFS for Lingjun is in invitational preview. To use CPFS for Lingjun, submit a ticket to add your account to the whitelist.

  • An available Lingjun cluster. Note the cluster ID for file system configuration.

Supported compute resources

CPFS for Lingjun supports only the following compute resources:

  • Platform for AI (PAI), including Lingjun resources, general computing resources of PAI, and single-tenant Lingjun resources

  • GPU-accelerated workloads deployed in high-performance networks in Container Compute Service (ACS)

Important

CPFS for Lingjun does not support Elastic Compute Service (ECS) instances. Verify that your compute environment uses PAI or ACS before creating a file system.

Procedure

  1. Log on to the NAS console.

  2. On the Overview tab of the Overview page, click Create below CPFS for Lingjun in the File System Selection Guide section.

  3. On the CPFS for Lingjun (pay-as-you-go) page, configure the following parameters.

    Parameter

    Required

    Description

    Zone

    Yes

    Select the zone where your Lingjun cluster resides.

    Cluster ID

    Yes

    Select the Lingjun cluster for the file system.

    Capacity

    Yes

    Specify the maximum storage capacity. Estimate your data volume and allocate sufficient capacity. If usage exceeds the configured capacity, the file system returns a no space error.

    Resource Group

    No

    The resource group for the file system. Resource groups organize CPFS for Lingjun resources by category. Manage permissions, deploy resources, and monitor resources at the group level. For more information, see Best practices for designing resource groups. If no resource group is selected, the file system defaults to the default resource group. To create a resource group, click Create Resource Group, specify the Resource Group Identifier and Resource Group Name, and then click OK.

  4. Click Buy Now and complete the payment as prompted.

Verify the result

After payment, return to the NAS console and choose File System > File System List. The new file system appears with a creating status.

Next steps

After creation, mount the file system to your compute resources. The mounting method varies by resource type:
