These disk | have GPT partitions so I can use fdisk I am not sure about the "incompatible feature error" . May be you could try fdisk or cfdisk. It is usually a good idea to "free" the device before doing partition resizes. We had done it (resizing cow2) once and it was successful , we had to although convert from cow2 to raw , append a new dd'ed file and user fdisk over the raw image. eventually it worked. what is the size of your cow2 device if its not huge you may consider backing it up and restore to a larger device. hope it helps. mallah.
