Description
Hi,
The copy operations for files and for rbd images are too slow. The ceph is a copy on write system I think the copies inside same ceph should be created with a same speed as a snapshots. In current stage I can create snapshot for 10GB files less than in a second and it will take more than a minute to copy it.

A 'clone' operation that does copy-on-write is coming in the next couple weeks. See #988

Is clone for rbd only or for files too.
Copy of files is slow too.
