Like I said this will work (not from a USB drive though) but you would have to create a Volume Group that will be different to the one it will be in. Also how would you integrate with your RAID controller or RAID set. I understand what you are trying to do and the need for it but there is more to this then just adding a drive. This is a feature we do not have. Though I do think our engineers should look into this.Originally Posted by pturnbull
