    Description

      Currently only default stripe count is supported in striped directory, which is landed on 2.6. We should also support default stripe index, so the subdirectories will be created at the MDT indicated by default stripe index, similar as default stripe index for files. And if the default stripe_index is -1, it will choose MDT evenly among all of MDTs.

            Description Original: With default stripe_index, the subdirectories can be created on the MDT with specified index in default EA. If the default stripe_index is -1, it will choose MDT evenly among all of MDTs similar as creating object on OST.
