Oddly, it seems I can't change the partitions of a previously formatted raid disk. When I use fdisk to repartition a drive previously formatted with the type set to Linux autoraid detect, I reboot only to find the autoraid partitions are still there. I have stopped the raid devices, but it seems I can't kill the persistent superblock. I tried reformatting with mke2fs and of course that failed to do the trick. It doesn't seem like this should be difficult, but I've spent several hours trying this. Any suggestions appreciated. Regards and thanks for a great program with mdadm.
