  36 # DESCRIPTION:
  37 #       Verify a snapshot will only be allowed if there is enough free pool
  38 #       space outside of this refreservation.
  39 #
  40 # STRATEGY:
  41 #       1. Setting quota and refservation
  42 #       2. Verify snapshot can be created, when used =< quota - refreserv
  43 #       3. Verify failed to create snapshot, when used > quota - refreserv
