I am removing gjournal from all of our machines. I did it many times
befor with FreeBSD 7.x versions without problem, but on two machines
upgraded to 8.3, there is the same problem on both of them. The gjournal
does not want to stop.
There is a list of steps I did:
# uname -srmi
FreeBSD 8.3-RELEASE amd64 GENERIC
# df -h -i /vol1/
Filesystem Size Used Avail Capacity Mounted on
/dev/mirror/gm0s2g.journal 781G 59G 659G 8% /vol1

# gjournal stop -v mirror/gm0s2g.journal
Done.
And then log/messages is spammed with following error every 5 seconds
# tail -f /var/log/messages

^C^C
kldunload hangs, I can't interupt it by Ctrl+C
Next commands were done in another ssh screen
# gjournal clear -v mirror/gm0s2e mirror/gm0s2g
Metadata cleared on mirror/gm0s2e.
Cannot clear metadata on mirror/gm0s2g: Operation not permitted.
gjournal: Not fully done.

This exact steps were previously done on 7.x machines without any problem.
On 8.3 machines, nothing stop gjournal and only reboot without
geom_journal loaded solved this problem.
Is there any other way to stop it without reboot?
