Hi, I am set to resize OSDs in ceph cluster to extend overall cluster capacity, by adding 40GB to each of disk and noticed that after disk resize and OSD restart RAW USE size grows proportionally to new size, ex. by 20GB while DATA remains the same, which makes new space not readily available. Here is the osd output of cluster: kubectl -n rook-ceph exec -it deploy/rook-ceph-tools -- ceph osd df ID  CLASS  WEIGHT   REWEIGHT  SIZE     RAW USE  DATA     OMAP     META      AVAIL    %USE   VAR   PGS  STATUS 1    hdd  0.09769   1.00000  100 GiB   83 GiB   82 GiB  164 MiB   891 MiB   17 GiB  82.79  1.00   77      up 3    hdd  0.09769   1.00000  100 GiB   83 GiB   82 GiB  355 MiB   772 MiB   17 GiB  82.74  1.00   84      up 2    hdd  0.09769   1.00000  100 GiB   84 GiB   82 GiB  337 MiB   1.3 GiB   16 GiB  83.88  1.01   82      up 4    hdd  0.09769   1.00000  140 GiB  125 GiB   84 GiB  148 MiB   919 MiB   15 GiB  89.24  1.07   80      up 6    hdd  0.09769   1.00000  140 GiB  106 GiB  104 GiB  333 MiB  1015 MiB   34 GiB  75.47  0.91  107      up 7    hdd  0.09769   1.00000  140 GiB  118 GiB   97 GiB  351 MiB   1.2 GiB   22 GiB  84.48  1.02  101      up                        TOTAL  720 GiB  598 GiB  531 GiB  1.6 GiB   6.1 GiB  122 GiB  83.10 MIN/MAX VAR: 0.91/1.07  STDDEV: 4.06 The OSDs I managed to extend are 7, 6 and 4. Only OSD number 6 detected new size and did not inflate RAW USE, OSD 7 and 4 have RAW USE vs DATA gap. kubectl -n rook-ceph exec -it deploy/rook-ceph-tools -- ceph df --- RAW STORAGE --- CLASS     SIZE    AVAIL     USED  RAW USED  %RAW USED hdd    720 GiB  122 GiB  598 GiB   598 GiB      83.10 TOTAL  720 GiB  122 GiB  598 GiB   598 GiB      83.10 --- POOLS --- POOL               ID  PGS   STORED  OBJECTS     USED  %USED  MAX AVAIL .mgr                1    1  449 KiB        2  1.3 MiB      0     16 GiB cephfs-metadata     2   16  832 MiB  245.62k  2.4 GiB   4.80     16 GiB cephfs-replicated   3  128  176 GiB  545.23k  530 GiB  91.63     16 GiB replicapool         4   32     19 B        2   12 KiB      0     16 GiB This reports nearly 600GB used, while it should be more like 530GB as cephfs-replicated pool is reporting its data usage. Any ideas why is this happening? Should I continue with extension of all OSDs to 140GB to see if that makes a difference? Br, merp.
