The other thing is that only teh osd_failsafe_full_ratio is a runtime 
option now (for the osd); the other ones only affect the mon during the 
mkfs stage.  The real thresholds are now stored in the OSDMap itself (see 
'ceph osd dump | grep full') and can be modified with

 ceph osd set-backfillfull-ratio <float[0.0-1.0]>
 ceph osd set-full-ratio <float[0.0-1.0]>
 ceph osd set-nearfull-ratio <float[0.0-1.0]>
