39 # ID: reservation_012_pos
43 # A reservation guarantees a certain amount of space for a dataset.
44 # Nothing else which happens in the same pool should affect that
45 # space, i.e. even if the rest of the pool fills up the reserved
46 # space should still be accessible.
49 # 1) Create 2 filesystems
50 # 2) Set a reservation on one filesystem
51 # 3) Fill up the other filesystem (which does not have a reservation
52 # set) until all space is consumed
53 # 4) Verify can still write to the filesystem which has a reservation
55 # TESTABILITY: explicit
57 # TEST_AUTOMATION_LEVEL: automated
59 # CODING_STATUS: COMPLETED (2005-07-04)
