In general they should be 1 ("in") or 0 ("out"), unless you are making small corrections in the placement. To adjust the relative weights on the disks, you want to adjust the CRUSH weights on the left (second column): ceph osd crush reweight $OSD $WEIGHT sage > > Does anyone see where the error is in the crushmap that I can fix it?
