Description of problem: [RFE] KRBD: Support for more RBD features, e.g. object map, exclusive lock etc Version-Release number of selected component (if applicable): Red Hat Ceph Storage 1.3 1. The krbd module does not support exclusive lock / object map / fast-diff / deep flatten / journaling features and also stripping. 2. Basically only supports layering 3. Development is in-progress for exclusive lock support and object map support.
Jewel will also get support for mapping RBD images as network block devices (NBD), we will be able to get a raw device that supports all the new features (since it is using librbd via a user-space daemon). Then NBD could make to Red Hat Ceph Storage 2.0 release which would be Jewel based.
