[ceph-users] Cache pools at or near target size but no evict happen

Hi, I had configured a cache tier with max object counts 500k. But no evict happens when the object counts hit the configured maximum. Anyone experienced this issue? What should I do? $ ceph health detail HEALTH_WARN 1 cache pools at or near target size CACHE_POOL_NEAR_FULL 1 cache pools at or near target size cache pool 'cached-hdd-cache' with 887.11k objects at/near target max 500k objects $ ceph df | grep -e "POOL\|cached-hdd" POOLS: POOL ID STORED OBJECTS USED %USED MAX AVAIL cached-hdd 24 1.4 TiB 1.52M 1.4 TiB 0.60 78 TiB cached-hdd-cache 25 842 GiB 887.14k 842 GiB 15.97 1.4 TiB $ ceph osd pool get cached-hdd-cache all size: 3 min_size: 1 pg_num: 128 pgp_num: 128 crush_rule: nvme-repl-rule hashpspool: true nodelete: false nopgchange: false nosizechange: false write_fadvise_dontneed: false noscrub: false nodeep-scrub: false hit_set_type: bloom hit_set_period: 1200 hit_set_count: 4 hit_set_fpp: 0.05 use_gmt_hitset: 1 target_max_objects: 500000 target_max_bytes: 1099511627776 cache_target_dirty_ratio: 0 cache_target_dirty_high_ratio: 0.7 cache_target_full_ratio: 0.9 cache_min_flush_age: 0 cache_min_evict_age: 0 min_read_recency_for_promote: 1 min_write_recency_for_promote: 1 fast_read: 0 hit_set_grade_decay_rate: 20 hit_set_search_last_n: 1 pg_autoscale_mode: warn Regs, Icy
