hi:
I am using the same verion with you.
This set only effects new created volumes.

Hi xizhiyong,
    Thanks for your infomation. I am using Jewel right now(10.1.2), the setting "rbd_default_features = 3" not working for me.
And this setting will enable "exclusive-lock, object-map, fast-diff, deep-flatten" features.




Best wishes,
Mika

That's true for me too.
You can disable them via set in the conf file.

#ceph.conf
rbd_default_features = 3
#meens only enable layering and striping

Hi cephers,  
    Had the same issue too. But the command "rbd feature disable" not working to me.
Any comment will be appreciated.

$sudo rbd feature disable timg1 deep-flatten fast-diff object-map exclusive-lock
rbd: failed to update image features: (22) Invalid argument
2016-04-21 15:53:10.260671 7f95ff5d9d80 -1 librbd: failed to update features: (22) Invalid argument



Best wishes,
Mika

None of the "new" features are currently supported by krbd.  4.7 will
support exclusive-lock with most of the rest following in 4.8.

You don't have to recreate images: while those features are enabled in
jewel by default, you should be able to dynamically disable them with
"rbd feature disable imagename deep-flatten fast-diff object-map
exclusive-lock".

Thanks,
