This is the main problem. Your MBR' slice is bigger than actual space
you have. The only way to fix this - recreate slice.
You can break your mirror, recreate the slice (NOTE: you must preserve
one sector for the gmirror's meta-data), then copy your data to the
newly created slice, then reboot from the new slice and recreate mirror.
