# DESCRIPTION:
|
|
#
|
|
# ZFS allows reservations to be set on filesystems and volumes, provided
|
|
# the reservation is less than the space available in the pool.
|
|
#
|
|
# STRATEGY:
|
|
# 1) Create a regular and sparse volume
|
|
# (filesystem already created by default_setup)
|
|
# 2) Get the space available in the pool
|
|
# 3) Set a reservation on the filesystem less than the space available.
|
|
# 4) Verify that the 'reservation' property for the filesystem has
|
|
# the correct value.
|
|
# 5) Reset the reservation to 'none'
|
|
# 6) Repeat steps 2-5 for both volume types
|
|
