    Description

      We have users that will set directory stripe count by using "-1" as in
      "lfs setdirstripe -c -1".

      Filesystem with small number of MDTs (4-8) this was ok. But as the MDT count gets lager (>32) this is not always desirable. Most of the time we don't want users to set directory stripe counts so large. We would like config option for max default directory size setting for ("lfs setdirstripe -c -1"). But would still like the ability to allow setting stripe counts larger for those who explicitly request it, but not unintentionally.
