# ID: quota_002_pos
#
# DESCRIPTION:
# A zfs file system quota limits the amount of pool space
# available to a given ZFS file system. Once exceeded, it is impossible
# to write any more files to the file system.
#
# STRATEGY:
# 1) Apply quota to the ZFS file system
# 2) Exceed the quota
# 3) Attempt to write another file
# 4) Verify the attempt fails with error code 49 (EDQUOTA)
#
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
