Create CephFS File Storage Type Storage Class

CephFS file storage is a built-in Ceph file storage system that provides the platform with a Container Storage Interface (CSI)-based storage access method, offering a secure, reliable, and scalable shared file storage service suitable for scenarios such as file sharing and data backup. Before proceeding, you must first create a CephFS file storage class.

After binding the storage class in a Persistent Volume Claim (PVC), the platform will dynamically create persistent volumes on the nodes according to the persistent volume claim for business applications.

Deploy Volume Plugin

After clicking Deploy, on the Distributed Storage page, Create Storage Service or Access Storage Service.

Create Storage Class

  1. Go to Platform Management.

  2. In the left navigation bar, click Storage Management > Storage Classes.

  3. Click Create Storage Class.

    Note: The following content is provided as an example in form format; you may also choose to create it using YAML.

  4. Select CephFS File Storage and click Next.

  5. Configure the relevant parameters according to the following instructions.

    ParameterDescription
    Reclaim PolicyThe reclaim policy for persistent volumes.
    - Delete: When the persistent volume claim is deleted, the bound persistent volume will also be deleted.
    - Retain: The bound persistent volume will remain, even if the persistent volume claim is deleted.
    Access ModesAll access modes supported by the current storage. Only one of these modes can be selected when declaring persistent volumes later.
    - ReadWriteOnce (RWO): Can be mounted as read-write by a single node.
    - ReadWriteMany (RWX): Can be mounted as read-write by multiple nodes.
    Allocate ProjectPlease allocate projects that can use this type of storage.
    If there are currently no projects that need to use this type of storage, you may choose not to allocate them for now and update later.

    Tip: The following parameters need to be set in the distributed storage and will be applied directly here.

    • Storage Cluster: The built-in Ceph storage cluster in the current cluster.

    • Storage Pool: The logical partition used for data storage in the storage cluster.

  6. Click Create.
