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.

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.
