I don't think so, check this out: # id weight type name up/down reweight -6 3.05 root ssd -7 0.04999 host ceph-01-ssd 11 0.04999 osd.11 up 1 -8 1 host ceph-02-ssd 12 0.04999 osd.12 up 1 -9 1 host ceph-03-ssd 13 0.03999 osd.13 up 1 -10 1 host ceph-04-ssd 14 0.03999 osd.14 up 1 As you can see, only host ceph-01-ssd has the same weight as its osd, the other three hosts have weight "1" which is different from their associated osd. If the weight of the host -should- be the sum of all osd weights on this hosts, then my question becomes: how do I make that so for the three hosts where this is currently not the case? Thanks, Erik.
