Thanks JC , it worked , now cache tiering agent is migrating data between
tiers.
But Now , i am seeing a new ISSUE : Cache-pool has got some EXTRA objects ,
that is not visible with # rados -p cache-pool ls but under #ceph df i can see
the count of those objects.
[root@ceph-node1 ~]# ceph
Hi Karan,
may be the statistical information about the temperature of the objects in the
pool that has to be maintained by the flushing/eviciting agent?
Otherwise, hard to say from my seat.

Hello Cephers
I have created a Cache pool and looks like cache tiering agent is not able to
flush/evict data as per defined policy. However when i manually evict / flush
data , it migrates data from cache-tier to storage-tier
Kindly advice if there is something wrong with policy or anything
Hi Karan,
May be setting the dirty byte ratio (flush) and the full ratio (eviction). Just
try to see if it makes any difference
- cache_target_dirty_ratio .1
- cache_target_full_ratio .2
Tune the percentage as desired relatively to target_max_bytes and
target_max_objects. The first threshold
