# DESCRIPTION:
|
|
#
|
|
# A reservation cannot exceed the quota on a dataset
|
|
#
|
|
# STRATEGY:
|
|
# 1) Create a filesystem and volume
|
|
# 2) Set a quota on the filesystem
|
|
# 3) Attempt to set a reservation larger than the quota. Verify
|
|
# that the attempt fails.
|
|
# 4) Repeat 2-3 for volume
|
|
