Slight clarification: to disable these features on existing images, you should run the following: rbd feature disable deep-flatten,fast-diff,object-map, exclusive-lock (note the commas instead of the spaces when disabling multiple features at once). -- Jason On Thu, Apr 21, 2016 at 4:48 AM, I

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 2016-04-21 16:56 GMT+08:00 席智勇 : > That'

I had the same issue when testing on Ubuntu xenial beta. That has 4.4, so should be fine? I had to create images without the new RBD features to make it works. % ceph -v ceph version 10.1.2 (4a2a6f72640d6b74a3bbd92798bb913ed380dcd4) % modinfo rbd filename: /lib/modules/4.4.0-18-generic/kern

Using any kernel >= 4.2 shouldn't have any problem. If you are using kernel version < 4.2, disable the recent features except layering. Varada On Monday 18 April 2016 02:41 PM, 席智勇 wrote: thanks for ur reply~ I did some search, and found the reason, like the mail(
