# __stc_assertion_start
#
# ID: reservation_016_pos
#
# DESCRIPTION:
#
# In pool with a full filesystem and a regular volume (with implicit
# reservation) destroying the volume should allow more data to be written 
# to the filesystem
#
#
# STRATEGY:
# 1) Create a regular (non-sparse) volume
# 2) Create a filesystem at the same level
# 3) Fill up the filesystem
# 4) Destroy the volume
# 5) Verify can write more data to the filesystem
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-19)
