Oh, I see. Your concerns are about client-side cache.
I'm sorry for I misunderstood your question.

Hello Webert,Thank you for your response.I am not interested in the SSD cache tier pool at all as that is on the Ceph Storage Cluster Server and is somewhat well documented/understood.My question is regards enabling caching at the ceph clients that talk to the Ceph Storage Cluster.thanks,AnishOn Tuesday, August 1, 2017, 9:55:39 AM PDT, Webert de Souza Lima <webert.boss@xxxxxxxxx> wrote:Hi Anish, in case you're still interested, we're using cephfs in production since jewel 10.2.1.I have a few similar clusters with some small set up variations. They're not so big but they're under heavy workload.- 15~20 x 6TB HDD OSDs (5 per node), ~4 x 480GB SSD OSDs (2 per node, set for cache tier pool)- About 4 mount points per cluster, so I assume it translates to 4 clients per cluster- Running 10.2.9 on Ubuntu 4.4.0-24-generic now.Cache Tiering is enabled for the CephFS on a separate pool that uses the SSDs as OSDs, if that's really what you wanna know.Cya,Regards,Webert LimaDevOps Engineer at MAV TecnologiaBelo Horizonte - BrasilOn Mon, Jul 24, 2017 at 3:27 PM, Anish Gupta <anish_gupta@xxxxxxxxx> wrote:Hello,Can you kindly share their experience with the bulit-in FSCache support with ceph?Interested in knowing the following:- Are you using FSCache in production environment?- How large is your Ceph deployment?- If with CephFS, how many Ceph clients are using FSCache- which version of Ceph and Linux kernelthank you.Anish
