You can check linux source code to see the feature supported by kernel client. e.g. linux 4.13-rc5 (https://github.com/torvalds/linux/blob/v4.13-rc5/drivers/block/rbd.c) in drivers/block/rbd.c: /* Feature bits */ #define RBD_FEATURE_LAYERING(1ULL<<0) #define RBD_FEATURE_STRIPINGV2

It would be much better to explain why as of today, object-map feature is not supported by the kernel client, or document it. On Tue, Aug 15, 2017 at 8:08 PM, Ilya Dryomov wrote: > On Tue, Aug 15, 2017 at 11:34 AM, moftah moftah wrote: >> Hi All, >> >> I have search everywhere for some sort of t

Hi All, I have search everywhere for some sort of table that show kernel version to what rbd image features supported and didnt find any. basically I am looking at latest kernels from kernel.org , and i am thinking of upgrading to 4.12 since it is stable but i want to make sure i can get rbd imag
