I can rebuild what is not dispensable, but 1) It'd be easier to restore, and 2) I thought I knew how to restore (guess I was wrong), so I'd like to figure that out so I can do it in the future, if needed. I'm sure it's just a matter of finding out what I need to do in the config file. What's puzzling is when I type: mdadm --examine --scan /dev/hde /dev/hdf /dev/hdg /dev/hdh I get: ARRAY /dev/md0 level=raid5 num-devices=3 UUID=d6fd4af2:5e5d0da2:9dec7c5f:ad60c25d devices=/dev/hdf I thought /dev/hde was the first drive, but it's possible for some reason I used /dev/hdf. That means I'm not sure which of the four was the spare. I don't see why it only recognized hdf and didn't include the other two "in use" drives as well (I can understand it leaving out the spare). I tried to find a mailing list for mdadm or a FAQ and found the closest it has to a mailing list is the Linux Kernel list. > Yes, you can create a seperate partition for /boot.

Cool. I didn't realize that. I have some small 2GB drives that I could easily use as a RAID 1 for the boot. (It's a shame you can't still get small drives like that for cheap!)
