I was just going by : docs.ceph.com/docs/master/start/os-recommendations/
Which states 4.9
docs.ceph.com/docs/master/rados/operations/crush-map
Only goes as far as Jewel and states 4.5
Not sure where else I can find a concrete answer
to if 4.10 is new enough.
Well, it looks like docs may need to be revisited as I was unable to
use kcephfs on 4.9 with luminous before downgrading tunables, not
sure about 4.10.

Hello,
Have recently upgraded a cluster to Luminous (Running
Proxmox), at the same time I have upgraded the Compute
Cluster to 5.x meaning we now run the latest kernel
version (Linux 4.10.15-1)
Looking to do the following :
ceph osd
set-require-min-compat-client luminous
Does 4.10 kernel support luminous features? I am afraid (but do
not have info to back it up) that 4.10 is too old for Luminous
features.
Below is the output
of ceph features, the 4 number next to the last
row of luminous is as expected for the 4 Compute
nodes, are the other 4 spread across hammer &
jewel log's of when the node's last connected before
they was upgraded to Proxmox 5.0, am I safe to run
the above command? No other RBD resources are
connected to this cluster.
