Hi, checking my Ceph health status I get this warning: 1 subtrees have overcommitted pool target_size_bytes; 1 subtrees have overcommitted pool target_size_ratio The details are as follows: Pools ['hdb_backup'] overcommit available storage by 1.288x due to target_size_bytes 0 on pools [] However, the relevant settings POOL_TARGET_SIZE_RATIO_OVERCOMMITTED according to health checks <https://docs.ceph.com/docs/master/rados/operations/health-checks/> are not enabled: root@ld3955:~# ceph osd pool get hdb_backup target_size_ratio Error ENOENT: option 'target_size_ratio' is not set on pool 'hdb_backup' root@ld3955:~# ceph osd pool get hdb_backup target_size_bytes Error ENOENT: option 'target_size_bytes' is not set on pool 'hdb_backup' Therefore I would consider this warning as a bug.
