GBDE on md0 fails (was Re: How to encrypt data on backup?)

[Tak Pui LOU]

The machine with the tape drive has no OS installed on it yet. Anyway, I
tried it with vnode. "dump" runs without any problem. But, "restore"
stops after a few minutes. I did the following:

% mdconfig -a -t vnode -f img0 -u md0
% gbde init /dev/md0 -i -L lock
I change the sector size to 2048.
% gbde attach md0 -l lock
% dump -0aLu -b 2 -f /dev/md0.bde /home
% mdconfig -a -t vnode -f img1 -u md1
% newfs /dev/md1
% mount /dev/md1 /mnt
% cd /mnt
% restore -r -f /dev/md0.bde
...
The program stops and stay as a runaway process. Can't interrupt, quit,
kill, etc. When I reboot the machine, it still won't stop. I have to push
the reset button.
