>Description:
I'm not able to get rid of journaling on a gpt-labeled disk.
Journal creation works as expected.
Console output:
GEOM_JOURNAL: Journal 3251779739: ada5p2 contains data.
GEOM_JOURNAL: Journal 3251779739: ada5p1 contains journal.
GEOM_JOURNAL: Journal ada5p2 clean.

After stopping journaling I get the following console output:
GEOM_JOURNAL: Journal 3251779739: gptid/bbf0f112-fbb0-11e0-a819-000423dc1f94 contains journal.
GEOM_JOURNAL: Journal 3251779739: gptid/c688176f-fbb0-11e0-a819-000423dc1f94 contains data.
GEOM_JOURNAL: Journal gptid/c688176f-fbb0-11e0-a819-000423dc1f94 clean.

gjournal clear ada5p2 fails: 
Cannot clear metadata on ada5p2: Operation not permitted.
gjournal: Not fully done.

gjournal stop gptid/c688176f-fbb0-11e0-a819-000423dc1f94.journal leads to following console output:
GEOM_JOURNAL: Journal 3251779739: ada5p2 contains data.
GEOM_JOURNAL: Journal 3251779739: ada5p1 contains journal.
GEOM_JOURNAL: Journal ada5p2 clean.

this seems to be endless repeatable.
"gjournal clear" fails on all possible device names. 



>How-To-Repeat:
issuing the following commands on a clean disk (here /dev/ada5):
gpart label -s GPT ada5
gpart add -t freebsd-swap -s 2g ada5
gpart add -t freebsd-ufs  ada5
gjournal label ada5p2 ada5p1
gjournal stop ada5p2.journal
gjournal clear ada5p2
