Hi guys. What is 'RAW USE' in _df_ while there is no pool using given _osd_? Like so: -> $ ceph osd df tree | egrep '(osd\.(3|2|4)\  |ID)' ID  CLASS     WEIGHT   REWEIGHT  SIZE     RAW USE  DATA     OMAP    META     AVAIL    %USE   VAR   PGS  STATUS  TYPE NAME  2    MONERO  0.39059   1.00000  400 GiB  660 MiB   14 MiB   31 KiB  646 MiB  399 GiB   0.16  0.04    0      up          osd.2  3    MONERO  0.39059   1.00000  400 GiB  1.5 GiB   15 MiB  467 KiB  1.4 GiB  399 GiB   0.36  0.08    1      up          osd.3  4    MONERO  0.39059   1.00000  400 GiB  567 MiB   15 MiB   50 KiB  553 MiB  399 GiB   0.14  0.03    1      up          osd.4 I have crush rule which is mean to - at least how I get it - separate osds: cluster is 3x nodes with 150GB + 400GB drives on each node - in case this matter, separation is suppose to be between different size drives. Should _raw use_ & _data_ not be always _zero_? many thanks, L.
