Probably I should use different email address from the next. I'm just interested in distributed filesystem, since I was the Lustre, the GPFS guy for a long period and now the Ceph. > 2.

If I've missed nothing, there is no discussion about deduplication feature (NOT dedumplication or dumpling) except [1] and there is no that feature in the Ceph and no consideration about that feature.

There should be any kind of consideration on the sly, I guess.
