I have 4 big fast drives that I want to run in RAID 10 (1+0). So, I'll need to mirror two sets of two disks, then stripe those two mirrors. So, how do I do this if I want this striped set of mirrors to be my entire fs? I can create both mirrors and have the entire fs on one of the mirrors (*mirror0*), but then I need to stripe it with the other mirrors (*mirror1*), and trying to create a stripe (*stripe*) from that a set of mirrors in which one of the mirrors contains the live file system does not work, obviously. I was thinking, very generally, of creating the fstab file that I'll need to point to the stripe instead of ad4 for example, rsyncing everything to a disk on a diffferent server, using a live CD to create the stripe, then rsyncing back to the stripe. I don't know if this will work, and haven't even come to a conclusion of the particulars needed. Of course, if there is a way to create the striped set off mirrors before installation then installing onto that stripe, that'd be perfect. I don't know if that can be done. I'm sure someone has configured a RAID 10 "standalone" system before. (Oh, I'm using 7.2). I'm just stuck at this point! Thanks for any and all help!
