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,
