It does, almost 8 GB for <300 OSDs, which increased several-fold over the last weeks (since we started upgrading Nautilus->Pacific). However, I didn't think much of it after reading in the docs about the hardware recommendations that require at least 60 GB per ceph-mon [1]. > I give all my mgrs and mons a restart and after a few minutes I can > see this osd map data getting purged from the mons.
