Hi, all!
I use Centos 7.4 and want to use ceph rbd.
I found that object-map, fast-diff can not work.
rbd image 'app':
size 500 GB in 128000 objects
order 22 (4096 kB objects)
block_name_prefix: rbd_data.10a2643c9869
format: 2
features: layering, exclusive-lock, object-map, fast-diff <===
flags: object map invalid, fast diff invalid

Ceph version is 12.2.2 (cf0baeeeeba3b47f9427c6c97e2144b094b7e5ba) luminous (stable)
Kernel: 3.10.0-693.el7.x86_64
So which kernel version support those feature?
I do not find answer on ceph docs.
