Hi all,When rados put file into pool, the pool usage increase fast, althrough
it configured a tier pool.
I check it with ceph df, USED and OBJECTS columns both increased(both cache
pool and base pool).
But it should't only write into cache tier layer pool?
pool configure like below:
jewel 10.2.5, cache pool 2 replications with 3 ssd, base pool 2 replications
with 2 hdd.
cache pool:
writeback target_bytes 264207763774 target_objects 10000000
hit_set bloom{false_positive_probability: 0.05, target_size: 0, seed: 0}
3600s
min_read_recency_for_promote 1 min_write_recency_for_promote 1
cache_target_dirty_ratio:0.4 (current usage percent only 23.47%)
NAME ID USED %USED MAX AVAIL OBJECTS
