-:Description: The number of disk threads, which are used to perform background

-:Description: Warning: it will only be used if both ``osd disk thread
-             ioprio class`` and ``osd disk thread ioprio priority`` are
-             set to a non default value.  Sets the ioprio_set(2) I/O
-             scheduling ``class`` for the disk thread. Acceptable
-             values are ``idle``, ``be`` or ``rt``. The ``idle``
-             class means the disk thread will have lower priority
-             than any other thread in the OSD. This is useful to slow
-             down scrubbing on an OSD that is busy handling client
-             operations. ``be`` is the default and is the same
-             priority as all other threads in the OSD. ``rt`` means
-             the disk thread will have precedence over all other
-             threads in the OSD. Note: Only works with the Linux Kernel
-             CFQ scheduler. Since Jewel scrubbing is no longer carried
-             out by the disk iothread, see osd priority options instead.

-             ioprio class`` and ``osd disk thread ioprio priority`` are
-             set to a non default value. It sets the ioprio_set(2)
-             I/O scheduling ``priority`` of the disk thread ranging
-             from 0 (highest) to 7 (lowest). If all OSDs on a given
-             host were in class ``idle`` and compete for I/O
-             (i.e. due to controller congestion), it can be used to
-             lower the disk thread priority of one OSD to 7 so that
-             another OSD with priority 0 can have priority.
