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.confrbd_default_features = 3#meens only enable layering and striping2016-04-21 16:00 GMT+08:00 Mika c <mika.leaf666@xxxxxxxxx>:Hi cephers,Had the same issue too.

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,
Ilya
