My manual on FreeBSD covers version 3.2 -- I realize there are newer versions, but my search of the FreeBSD web site doesn't turn up my answer. Is there a way to implement RAID-5 with a couple standard SCSI controllers (the kind at eBay for under $100) or do I need to buy a specialized RAID-5 controller card? Looking at the book, I see that I might be able to make a mirrored/striped system using 4 or 6 drives, but what I do not see is any information on whether or not FreeBSD allows me to "break the mirror", back-up one side of the mirror, and then restore the mirror and resynchonize. While I want to get the speed and reliability of RAID, I don't have a big budget. Am I asking for too much? :-) If it isn't too much, where do I go from here?
