Hello, I configured a stretched cluster on two datacenters. It's working fine, except this weekend the Raw Capicity exceeded 50% and the error POOL_TARGET_SIZE_BYTES_OVERCOMMITED showed up. The command "ceph df" is showing the correct cluster size, but "ceph osd pool autoscale-status" is showing half of the total Raw Capacity. What could be wrong? ---------------------------------------------------------------------------- [ceph: root@aqsoel11445 /]# ceph status cluster: id: adbe7bb6-5h6d-11ed-8511-004449ede0c health: HEALTH_WARN 1 MDSs report oversized cache 1 subtrees have overcommitted pool target_size_bytes services: mon: 5 daemons, quorum host1,host2,host3,host4,host5 (age 4w) mgr: aqsoel11445.nqamuz(active, since 5w), standbys: host1.wujgas mds: 2/2 daemons up, 2 standby osd: 12 osds: 12 up (since 5w), 12 in (since 9w) data: volumes: 2/2 healthy pools: 5 pools, 193 pgs objects: 17.31M objects, 1.2 TiB usage: 5.0 TiB used, 3.8 TiB / 8.8 TiB avail pgs: 192 active+clean 1 active+clean+scrubbing ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- [ceph: root@aqsoel11445 /]# ceph df --- RAW STORAGE --- CLASS SIZE AVAIL USED RAW USED %RAW USED ssd 8.8 TiB 3.8 TiB 5.0 TiB 5.0 TiB 56.83 TOTAL 8.8 TiB 3.8 TiB 5.0 TiB 5.0 TiB 56.83 --- POOLS --- POOL ID PGS STORED OBJECTS USED %USED MAX AVAIL .mgr 1 1 449 KiB 2 1.8 MiB 0 320 GiB cephfs.application-tst.meta 2 16 540 MiB 18.79k 2.1 GiB 0.16 320 GiB cephfs.application-tst.data 3 32 4.4 GiB 8.01k 17 GiB 1.33 320 GiB cephfs.application-acc.meta 4 16 11 GiB 3.54M 45 GiB 3.37 320 GiB cephfs.application-acc.data 5 128 1.2 TiB 13.74M 4.8 TiB 79.46 320 GiB ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- [ceph: root@aqsoel11445 /]# ceph osd pool autoscale-status POOL SIZE TARGET SIZE RATE RAW CAPACITY RATIO TARGET RATIO EFFECTIVE RATIO BIAS PG_NUM NEW PG_NUM AUTOSCALE BULK .mgr 448.5k 4.0 4499G 0.0000 1.0 1 on False cephfs.application-tst.meta 539.8M 4.0 4499G 0.0005 4.0 16 on False cephfs.application-tst.data 4488M 51200M 4.0 4499G 0.0444 1.0 32 on False cephfs.application-acc.meta 11430M 4.0 4499G 0.0099 4.0 16 on False cephfs.application-acc.data 1244G 4.0 4499G 1.1062 1.0000 0.9556 1.0 128 on False ----------------------------------------------------------------------------
