Bug description:
This is from a landscape OSA deployment. Several of my hardware nodes
have a /dev/nvme0n1 device, which is a PCIe SSD. For two of my nodes,
I've configured it for bcache, as a result on these nodes,
/dev/nvme0n1 is in use. However, on one node /dev/nvme0n1 is still
unused. As a result landscape selects this as a usable cinder disk and
passes it as a cinder block-device. When cinder is deployed to one of
the nodes with bcache, the config-changed hook fails.
