The ``chance_scheduler`` scheduler driver was deprecated in Pike
|
|
and has now been removed. You should enable the ``filter_scheduler``
|
|
driver instead. If ``chance_scheduler`` behavior is desired
|
|
(i.e. speed is valued over correctness) then configuring the
|
|
``filter_scheduler`` with only the ``AllHostsFilter`` enabled and
|
|
adjusting ``[filter_scheduler]/host_subset_size`` will provide similar
|
|
performance.
