I’ve come close more than once to removing that misleading 4% guidance.
The OP plans to use a single M.2 NVMe device - I’m a bit suspcious that the M.2
connector may only be SATA, and 12 OSDs sharing one SATA device for WAL+DB,
plus potential CephFS metadata and RGW index pools seems like a
des do you have for your cluster size? Do you have dedicated
or shared MDS with OSDs?

Hi Stefan
We use cephfs for our 7200CPU/224GPU HPC cluster, for our use-case
(large-ish image files) it works well.
We have 36 ceph nodes, each with 12 x 12TB HDD, 2 x 1.92TB NVMe, plus a
240GB System disk. Four dedicated nodes have NVMe for metadata pool, and
provide mon,mgr and MDS
