Creating a PVC Change Resource

This section describes how to create a PVC change resource based on a configured PVC change file.

  • Only the HyperMetro active-active (AA) mode is supported.
  • When a common volume is changed to a HyperMetro volume, only the storage volume at the primary site can be changed.
  • Do not use Huawei CSI to manage a PVC during PVC change resource creation.
  • Multiple VolumeModifyClaim resources cannot be created for the same PVC. If the target PVC needs to be changed for multiple times, perform the changes one by one.

Procedure

  1. Use a remote access tool, such as PuTTY, to log in to any master node in the Kubernetes cluster through the management IP address.

  2. Run the following command to create a PVC change.

    kubectl create -f volumemodifyclaim.yaml

  3. Query the creation result by following the instructions in Querying a PVC Change.
