Is not the problem here that you are trying to GPT label a gmirrored disc ? If you instead gmirror two GPT partitions then the problem goes away doesnt it ? Thats how I set things up - use parititoning on the ohysical drives, and then put the mirroring into the partitions thus created. Works fine, and doesnt suffer from any of the afforementioned problems. -pete.
