I'm playing with softraid on current (OpenBSD 4.5 GENERIC.MP#128 amd64) and getting to the point where I'm unable to take down or write-over existing devices. I can't find any existing device to remove, but am nonetheless unable to create a new RAID 0 array.
bioctl gives these complaints: # bioctl -c 0 -l /dev/sd0a,/dev/sd1a softraid0 bioctl: BIOCCREATERAID: Invalid argument # bioctl -d sd1 bioctl: delete volume sd1 failed # bioctl -d sd3 bioctl: Can't open sd3: Device not configured # bioctl -C force -d sd3 bioctl: Can't open sd3: Device not configured # bioctl -C force -d sd1 bioctl: delete volume sd1 failed # bioctl -i sd0 sd0: <JetFlash, TS4GJFT3, 8.07>, serial \\037 JetFlashTS4GJFT3 8.07 # bioctl -i sd1 sd1: <JetFlash, TS4GJFT3, 8.07>, serial \\037 JetFlashTS4GJFT3 8.07 dmesg gives this complaint: ... softraid0 at root softraid0: roaming device sd3a -> sd1a softraid0: not assembling partial disk that used to be volume 0 ... softraid0: not all chunks are of the native metadata format softraid0: can't attach metadata type 0 The steps I follow to try to make a clean start are: # A - Initialize partition tables for RAID array fdisk -iy sd0 fdisk -iy sd1 printf "d a\nq\n\n" | disklabel -E sd0 printf "d a\nq\n\n" | disklabel -E sd1 # B - Create RAID partitions printf "a\n\n\n\nRAID\nw\nq\n\n" | disklabel -E sd0 printf "a\n\n\n\nRAID\nw\nq\n\n" | disklabel -E sd1 # C - RAID 0, striping bioctl -c 0 -l /dev/sd0a,/dev/sd1a softraid0 but it's the last step, C, that gives an erorr, but A and B don't seem to be wiping the devices.
