# DESCRIPTION:
# Verify that 'zfs destroy' on a shared dataset, will unshare it.
#
# STRATEGY:
# 1. Create and share a dataset with sharenfs.
# 2. Verify the dataset is shared.
# 3. Invoke 'zfs destroy' on the dataset.
# 4. Verify the dataset is not shared.

{
	if datasetexists "$TESTPOOL/$TESTFS/shared1"; then
		log_must zfs destroy -f $TESTPOOL/$TESTFS/shared1

# 1. Create and share a dataset with sharenfs.
log_must zfs create \
	-o sharenfs=on -o mountpoint=$TESTDIR/1 $TESTPOOL/$TESTFS/shared1

#
# 2. Verify the datasets is shared.
#
# The "non-impl" variant of "is_shared" requires the dataset to exist.
# Thus, we can only use the "impl" variant in step 4, below. To be
# consistent with step 4, we also use the "impl" variant here.
#
log_must eval "is_shared_impl $TESTDIR/1"

# 3. Invoke 'zfs destroy' on the dataset.
log_must zfs destroy -f $TESTPOOL/$TESTFS/shared1

# 4. Verify the dataset is not shared.
log_mustnot eval "is_shared_impl $TESTDIR/1"

log_pass "'zfs destroy' will unshare the dataset."
