34# ID: quota_004_pos
35#
36# DESCRIPTION:
37# A zfs file system quota limits the amount of pool space
38# available to a given ZFS file system dataset. Once exceeded, it
39# is impossible to write any more files to the file system.
40#
41# STRATEGY:
42# 1) Apply quota to the ZFS file system dataset
43# 2) Exceed the quota
44# 3) Attempt to write another file
45# 4) Verify the attempt fails with error code 49 (EDQUOTA)
46#
47#
48# TESTABILITY: explicit
49#
50# TEST_AUTOMATION_LEVEL: automated
51#
52# CODING_STATUS: COMPLETED (2005-07-04)
