  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 #
