Hello, I'm using cache tiering with cephfs on latest ceph jewel release.
For my use case, I wanted to make new writes go "directly" to the cache pool , and any use other logic for promoting when reading, like after 2 reads, for example. I see that the following settings are available: hit_set_count hit_set_period min_read_recency_for_promote min_write_recency_for_promote Playing with those values I could see that the only way I could make the first writes go directly to the cache pool was setting the hit_set_count = 0. Doing that, the other options don't have any effect. I tried setting the hit_set_count and hit_set_period for any number above zero, and set min_write_recency_for_promote = 0 but that does not work as expected. Is that possible? Could it be arranged?
