Configuring PVs

Huawei CSI allows storage resources (LUNs or file systems) to be created on Huawei storage and provided for containers based on user settings. For details about the supported features, see Compatibility and Features of the storage device.

PV configurations can be classified into configuring dynamic PVs or static PVs, and managing PVs.

• Configuring dynamic PV does not require a PV to be created in advance. Huawei CSI automatically creates resources required by a PV on storage devices based on a StorageClass. In addition, you can create a PV when creating a PVC.
• Configuring a static PV requires the administrator to create required resources on a storage device in advance and use existing resources by creating a PV. In addition, you can specify the associated PV when creating a PVC.
• Managing PVs does not require a PV to be created in advance. You can specify the StorageClass and resource information on the storage device in a PVC. Create the PVC and PV at the same time, and manage all existing storage resources in the cluster.
