If a kernel device name change happens and a block device file
in the OSD directory becomes dangling link, this OSD fails
to start continuously. This problem can be resolved by confirming
the validity of the device file and recreating it if necessary.
The original problem happened in host-based clusters. A similar
problem exists in PVC-based clusters. In this case, if a PV,
corresponds to an existing OSD, and points to a missing block
device file, the OSD pod fails to consume this PV. Although this
behavior is undesirable, I don't think this problem should be
handled in Rook. If doing so, we must re-create the existing PV.
Rook shouldn't do such work.
