      We may want to change the volumeModes and accessModes for the destination volumes

      Two requests:

      1. By default, create a target DV without accessModes and volumeMode - let it pick the defaults from the storageProfile

        storage:
    resources:
      requests:
        storage: "34087042032"
    storageClassName: hostpath-csi-basic

      2. Still add an option to choose the accessModes and volumeMode and use the chosen values in the DV spec:

        storage:
    accessModes:
    - ReadWriteMany
    resources:
      requests:
        storage: "34087042032"
    storageClassName: hostpath-csi-basic
    volumeMode: Block

       

      Additional info: 

      Faced the issue when was migrating from OCS to HPP, my destination DV was created with ReadWriteMany Block, which is not supported by the destination storage class:
