Description

The description of OSD_OUT_OF_ORDER_FULL is

The utilization thresholds for backfillfull, nearfull, full, and/or failsafe_full are not ascending. In particular, we expect backfillfull < nearfull, nearfull < full, and full < failsafe_full.

see in :http://docs.ceph.com/docs/master/rados/operations/health-checks/?highlight=backfillfull%20ratio#osd-out-of-order-full

I set backfillfull to 0.8, nearfull to 0.84, but there is a err, as follows:

OSD_OUT_OF_ORDER_FULL full ratio(s) out of order
    backfillfull_ratio (0.8) < nearfull_ratio (0.84), increased
