    Description

      With patch https://review.whamcloud.com/35034 "LU-12273 lod: metadata overstriping" it is possible to create overstriped directories across MDTs using "lfs mkdir -C N", and with patch https://review.whamcloud.com/54192 "LU-16938 utils: setstripe overstripe multiple OST count" it is possible to specify an overstripe factor for each OST for "lfs setstripe -C -N".

      However, it is not possible to specify "lfs mkdir -C -N" to specify an overstripe factor for each MDT. It would be good to fix this inconsistency.
