Ok,
At moment my client use only nbd-rbd, can I use all these feature
or this is something unavoidable?
I guess it's ok.
Reading around seems that a lost feature cannot be re-enabled due
to back-compatibility with old clients.
... I guess I'll need to export and import in a new image fully
feature.
Is it?

All of the features you are talking about likely
require the exclusive-lock which requires the 4.9 linux kernel.
You cannot map any RBDs that have these features enabled with
any kernel older than that.
The features you can enable are layering, exclusive-lock,
object-map, and fast-diff. You cannot enable deep-flatten on
any RBD ever. RBD's can only be created with that feature.
You may need to enable these in a specific order. I believe
that the order I have the features listed is the order you
need to enable them in, at least that order should work.
Hi everybody,
I just realize that all my Images are completly without
features:
rbd info VHD-4c7ebb38-b081-48da-9b57-aac14bdf88c4
rbd image 'VHD-4c7ebb38-b081-48da-9b57-aac14bdf88c4':
size 102400 MB in 51200 objects
order 21 (2048 kB objects)
block_name_prefix: rbd_data.5fde2ae8944a
format: 2
features:
flags:
try to enabling them will get this error:
rbd: failed to update image features: (22) Invalid argument
2017-06-23 21:20:03.748746 7fdec1b34d80 -1 librbd: cannot update immutable features
I read on the guide I shoulded had place in the config
rbd_default_features
What can I do now to enable this feature all feature of
jewel on all images?
Can I insert all the feature of jewel or is there any
issue with old kernel?
Thanks,
Max
