    Description

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

      Filesystem with small number of OSTs (~200) this was ok. But as our OST count get lager (>400) this is not always desirable. Most of the time we don't want our users to set stripe counts so large. We would like config option for max default size setting for (lfs setstripe -c -1). But would still like the ability to allow setting stripe counts upto LOV_MAX_STRIPE_COUNT for those who really need it.
