For example, if I have a disk divided like this: |--------------ad0--------------| |-------------ad0s1-------------| |----ad0s1g-----|-----ad0s1d----| The metadata is written into the last sector, so when the stripe/concat classes are tasting they can't work out whether it belongs to ad0s1d, ad0s1 or ad0. I've had problems creating stripes and concats with this configuration. Regards Sam.
