      Cause:

      EDPM node disk images only supports a 512 bytes block size, which is incompatible with devices requiring a 4KiB (4096 byte) block size.

      Consequence:

      EDPM nodes fail to to deploy. Post-deployment partitioning validation finds no partitions or structures written to disk after the deployment operation, because the image was based on a 512 Byte layout. The host requires a 4KiB image, but the supplied image cannot be booted from that device.

      Workaround:

      A knowledge base article exists, https://access.redhat.com/articles/7096924, which can be used as the basis of a workaround to craft a custom 4KiB image based upon the existing image. Furthermore, depending on the block device controller block device (RAID or Disk) controller, settings may be available which permits setting a preferred default, but such will be highly vendor and configuration specific.

      Result:

      A modified EDPM image boots on newer hardware supporting only 4kB blocks, but also cannot be used on hardware which requires the 512 Byte block size. These block device required block sizes result in mutually incompatible images

      OpenStackDataPlaneNodeSet deployment fails on Dell R660 server with the following error:

       Normal ProvisioningError 30m metal3-baremetal-controller Image provisioning failed: Deploy step deploy.write_image failed on node b1376931-5e3b-4b3b-980c-7f07cdb75f01. Unable to find a valid partition table on the disk after writing the image. The image may be corrupted. Error: Unexpected error while running command.

      The image being copied is the `edpm-hardened-uefi.qcow2` image and it seems to have valid partitions:
