First mistake - wrong order. Create a mirror, than partition a mirror
provider.

If there is no mirror configured, you should be able to unload it.

Read manual page. Gmirror uses the last provider's sector for metadata.
If two or more providers share the same last sector (as in your case),
use '-h' option.
