I need some up to date information on how to set up a RAID-1 / RAID-Stripe when installing a new version of FreeBSD. I have several Pentium 2/3/4 computer that I need to install a os onto. But also several Sun Blade 100 that is still in good condition. Most of the computers have matching harddrives so I would like to run some kind of RAID on them.

Something Equal to LVM2 that is used under Linux would be great also.

Don't think I haven't read the handbook because I have with a fine tooth comb.

At the local library I only have old worthless books so no help there...

Any way you can help I would be grateful!

The book you want is by Michael W. Lucas - called "Absolute FREEBSD" (mine is 2nd edition). On page 545 the topic is "Striping Disks" using the gstripe kernel loadable module. It's a gold-mine reference book if you're doing FreeBSD admin. I used it to set up both RAID0 and RAID1 and the book made it easy. (gmirror is the other KLM you may want to look at)

If you simply want to mirror using the pair of matching drives in each machine, I recommend you install to one of the devices and mirror it to the 2nd device after the install. The FreeBSD handbook covers RAID1 in this scenario.

@Gioff: Just a nit-pick but he said stripe - not mirror, and there's a BIG difference. –  hotei Aug 27 '10 at 14:06

Just read the FreeBSD Handbook... its a truly great, free and up to date reference. Of course it also explains how to set up a raid. Of particular interest to you:
