Hi, Ceph version 12.2.13. Ceph status show ‘Health_Warn’ nearfull osd(s) and pool(s). No data in this nvme class pools and nvme osd’s, completely free. But meta values is so big in nvme osds. Why does meta values on OSDs shows huge disk usage? $ ceph health detail HEALTH_WARN 1 nearfull osd(s); 6 pool(s) nearfull OSD_NEARFULL 1 nearfull osd(s) osd.49 is near full POOL_NEARFULL 6 pool(s) nearfull pool 'VmImages_NVMe_FdChassis_Rp3' is nearfull pool '.rgw.root' is nearfull pool 'default.rgw.control' is nearfull pool 'default.rgw.meta' is nearfull pool 'default.rgw.log' is nearfull pool 'default.rgw.buckets.non-ec' is nearfull -- $ ceph df --cluster ceph GLOBAL: SIZE AVAIL RAW USED %RAW USED 501TiB 354TiB 147TiB 29.42 POOLS: NAME ID USED %USED MAX AVAIL OBJECTS VmImages_SSD_FdHost_Rp3 6 25.2TiB 33.26 50.6TiB 6990169 VmImages_NVMe_FdChassis_Rp3 8 19B 0 242GiB 2 VmImages_HDD_FdHost_Rp3 15 21.3TiB 35.33 39.0TiB 5755928 .rgw.root 16 1.77KiB 0 16.3TiB 11 default.rgw.control 17 0B 0 16.3TiB 8 default.rgw.meta 18 17.6KiB 0 16.3TiB 80 default.rgw.log 19 162B 0 16.3TiB 210 default.rgw.buckets.index 20 0B 0 50.6TiB 252 default.rgw.buckets.data 21 95.8GiB 0.24 39.0TiB 1561373 default.rgw.buckets.non-ec 22 0B 0 16.3TiB 4 default.rgw.buckets.data.ssd 25 0B 0 50.6TiB 0 $ ceph osd df tree | grep nvme ID CLASS WEIGHT REWEIGHT SIZE USE DATA OMAP META AVAIL %USE VAR PGS TYPE NAME 0 nvme 0.36378 1.00000 373GiB 313GiB 57.3MiB 25.8MiB 313GiB 59.0GiB 84.15 2.86 79 osd.0 7 nvme 0.36378 1.00000 373GiB 307GiB 57.4MiB 22.9MiB 307GiB 65.8GiB 82.32 2.80 70 osd.7 14 nvme 0.36378 1.00000 373GiB 313GiB 57.3MiB 25.9MiB 313GiB 59.3GiB 84.08 2.86 79 osd.14 21 nvme 0.36378 1.00000 373GiB 312GiB 57.4MiB 24.2MiB 312GiB 60.8GiB 83.68 2.85 78 osd.21 28 nvme 0.36378 1.00000 373GiB 316GiB 57.3MiB 29.8MiB 316GiB 56.4GiB 84.87 2.89 85 osd.28 35 nvme 0.36378 1.00000 373GiB 312GiB 57.4MiB 26.5MiB 312GiB 60.5GiB 83.75 2.85 80 osd.35 42 nvme 0.36378 1.00000 373GiB 311GiB 57.5MiB 25.5MiB 311GiB 61.9GiB 83.39 2.84 79 osd.42 49 nvme 0.36378 1.00000 373GiB 318GiB 57.3MiB 27.7MiB 318GiB 54.8GiB 85.28 2.90 90 osd.49 56 nvme 0.36378 1.00000 373GiB 303GiB 57.3MiB 20.2MiB 303GiB 69.5GiB 81.33 2.77 71 osd.56 63 nvme 0.36378 1.00000 373GiB 309GiB 57.4MiB 28.5MiB 309GiB 63.2GiB 83.02 2.82 82 osd.63 70 nvme 0.36378 1.00000 373GiB 312GiB 57.3MiB 26.2MiB 312GiB 60.5GiB 83.76 2.85 88 osd.70 77 nvme 0.36378 1.00000 373GiB 299GiB 57.4MiB 22.7MiB 299GiB 73.6GiB 80.24 2.73 69 osd.77 84 nvme 0.36378 1.00000 373GiB 312GiB 57.4MiB 31.7MiB 312GiB 60.2GiB 83.84 2.85 76 osd.84 91 nvme 0.36378 1.00000 373GiB 301GiB 57.3MiB 21.1MiB 301GiB 71.5GiB 80.80 2.75 76 osd.91 98 nvme 0.36378 1.00000 373GiB 285GiB 57.3MiB 15.7MiB 285GiB 87.6GiB 76.47 2.60 54 osd.98 105 nvme 0.36378 1.00000 373GiB 308GiB 57.3MiB 30.8MiB 308GiB 64.6GiB 82.67 2.81 86 osd.105 112 nvme 0.36378 1.00000 373GiB 264GiB 57.3MiB 26.0MiB 264GiB 108GiB 70.99 2.42 84 osd.112 119 nvme 0.36378 1.00000 373GiB 297GiB 57.3MiB 23.6MiB 297GiB 75.1GiB 79.85 2.72 74 osd.119 126 nvme 0.36378 1.00000 373GiB 292GiB 57.3MiB 22.8MiB 292GiB 80.2GiB 78.48 2.67 68 osd.126 133 nvme 0.36378 1.00000 373GiB 294GiB 57.3MiB 24.1MiB 294GiB 78.7GiB 78.87 2.68 70 osd.133
