    Description

      From 2.14, if client doesn't specify default LMV hash type, MDS will use the default one (from tunable option lod.*.mdt_hash). But before 2.14, default LMV hash type should be set explicitly, otherwise in real creation time mkdir will returns -EBADF.

      2.12.6 is running on server and 2.14.0 is running on the client.
