Also more interesting is this Stratis project that started up a few months ago:

Which also includes this design document:

This concept, if successfully implemented, does not seem to achieve
anything beyond "hide the complexity of its implementation from the user".
No actual new functionality, no reason to assume any additional robustness
or stability, and certainly not a new filesystem, just yet-another-wrapper.
Keeping users from understanding the complexity of a storage system
they use is not a benefit for all but the most trivial use cases.
And I find it symptomatic that the section "D-Bus Access Control" in
StratisSoftwareDesign.pdf is empty.
So it's going to use existing device mapper, md, some LVM
stuff, XFS
That is the only part of the Stratis concept that looks reasonable to me.
