You have to feed mdadm the drives you want specifically; there's no scattershot approach. Let's say that the drives are /dev/sdf, /dev/sdg, /dev/sdh and /dev/sdi. (You can re-confirm what drive is what via hdparm -i, or smartctl.) If you have data on them, it will be wiped out. You should copy off anything important, and then run wipefs on each of them. Then, creation is # mdadm -C /dev/md0 --level=10 --raid-devices=4 /dev/sdf /dev/sdg /dev/sdh /dev/sdi (assuming you want it named /dev/md0 and there isn't one already) Then you can make a filesystem on /dev/md0 and put it in your fstab, mount it, and copy data over to it. > What I'd like to do when I install bullseye, is use this raid10 for > the /home partition in the bullseye install. The installer will recognize it as an md RAID and can be told that you want to use it as-is, or you can destroy it and re-create it without data. -dsr-
