I'm following up to the list, because several helpful people sent me suggestions, but the solution (from Greg Lehey) was rather more non-obvious. In summary (hopefully with keywords that will attract the search of the next person to have problems), I was getting the following from vinum: [2:40:539]root@catamaran:/dev>vinum mirror -n media /dev/ad1s1g /dev/ad2s1g Can't create drive vinumdrive0, device /dev/ad1s1g: Invalid argument (22) In this case, I was helping someone format drives into a vinum mirroring configuration and they had already failed a number of times. It would appear that vinum doesn't respond entirely well to garbage on the disk and "vinum dumpconfig -v" showed partial remanents of previous configs. The solution ended up being to dd /dev/zero onto the disk with: dd if=/dev/zero of=/dev/ad1s1g count=10 seek=2 (and then reboot) (aparently, the seek argument can vary, according to Greg) If memory serves, disklabel is also sensitive to disk garbage. It would really be handy if we had a more "official" way of blanking the beginning of partitions... posibly part of fdisk's task.
