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.
