gbde on gmirror supported?

[scion+fbsdq at webrelay.net]

Greetings,

I have two drives (3 parts each) mirrored with gmirror.
System performs as advertized.

dna# gmirror label -v -b load hgsa da2 da3      
Metadata value stored on da2.
Metadata value stored on da3.
Done.
dna# ls /dev/mirror
hgsa    hgsaa   hgsac   hgsas1  hgsas1c hgsas1d hgsas1e hgsas1f
dna# newfs /dev/mirror/hgsas1d
/dev/mirror/hgsas1d: 36864.0MB (75497472 sectors) block size 16384, fragment size 2048
        using 201 cylinder groups of 183.77MB, 11761 blks, 23552 inodes.
super-block backups (for fsck -b #) at:
 160, 376512, 752864, 1129216, 1505568, 1881920, 2258272, 2634624, 3010976, 3387328, 3763680,
...

Great, so now I'd like to use gbde on hgas1f.

dna# gbde init /dev/mirror/hgsas1f -L /etc/hgsas1f.lock
Enter new passphrase:
Reenter new passphrase: 
dna# gbde attach mirror/hgsas1f -l /etc/hgsas1f.lock
Enter passphrase: 
dna#

So everything *seems* cool, but...


dna# ls /dev/mirror/hgsas1f
/dev/mirror/hgsas1f
dna# ls /dev/mirror/hgsas1f.bde
ls: /dev/mirror/hgsas1f.bde: No such file or directory
dna# ls /dev/mirror
hgsa    hgsas1  hgsas1c hgsas1d hgsas1e hgsas1f
dna# ls /dev/*bde
zsh: no matches found: /dev/*bde


Should this have worked?  Did I miss something obvious? obscure?

Thanks,
