Hello!

I cannot delete the gmirror metadata with gmirror clear, I guess
the problem is that the partition size changed, because I put the
disk into a raid-controller and that the controller changed the
disk size, because it added metadate to it, too.

Now my question is, how can I clear the metadata block via dd?
I think dd skip=3D(size_of_hd_in_512_bytes_blocks-gmirror-size)
if=3D/dev/zero of=3D/dev/amrd0 count=3D?? should do the job, but I am not
aware how many bytes to clear.

A more detailled description can be found on
http://home.schottelius.org/~nico/unix/freebsd/gmirror-remove

Thanks for any hint,

Nico
