This helps for a years. For the mons. But sometimes not for the OSD
Alex, I suggest to you - use pgremapper for cancel-backfill. Then see for OSD 
status - maps is prune or not
In case, when everything is clean, but maps are not prune - I issued new 
osdmaps via setting and then unsetting osd flags (noout, for example). After 
each new map, by default OSD should prune 30 old osdmaps

P.S.: Am I right in understanding that the OSD deletes the old osdmaps (prune) 
only if a new one is issued (as trigger)?
