# ID: quota_001_pos
#
# DESCRIPTION:
#
# A ZFS file system quota limits the amount of pool space
# available to a file system. Apply a quota and verify
# that no more file creates are permitted.
#
# STRATEGY:
# 1) Apply quota to ZFS file system
# 2) Create a file which is larger than the set quota
# 3) Verify that the resulting file size is less than the quota limit
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
#
