#
# ID: reservation_011_pos
#
# DESCRIPTION:
#
# ZFS has two mechanisms dealing with space for datasets, namely
# reservations and quotas. Setting one should not affect the other,
# provided the values are legal (i.e. enough space in pool etc).
#
# STRATEGY:
# 1) Create one filesystem
# 2) Get the current quota setting 
# 3) Set a reservation 
# 4) Verify that the quota value remains unchanged
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
#
