Re: URGENT "md" question: RAID partitions lack device nodes



Unless something with raidtools has drastically changed and I didn't notice,
there is no such thing as partitioning an md device. Instead, you'd
partition the disks themselves, and then create RAID 1s from those
partitions.

E.g., instead of making hda1 and hdb1 into md0 and trying to partition md0,
partition hda and hdb in identical ways and then create RAID 1s md0, md1,
md2, etc.
