With linux software RAID, the partitions don't have to be the same size (last I knew). You only get data protection up to the size of the smallest partition tho. (I don't remember whether it continues filling up space on the remaining drives, or whether it just runs out of space at that point tho. I would suspect the latter). I have a few pieces of advice for you: - Avoid software RAID if possible, especially in a commercial environment. The cost of a 3ware controller pretty much covers the time saved when a disk dies and you don't have to spend a couple hours monkeying with the array. (Software RAID arrays sometimes make the box fall over anyway when a disk dies. Your data may be saved, but the box still crashes.) - if you want a separate boot device for whatever reason, just put it on a wholly separate disk (or array of disks). I would suggest putting your important data on the array, and then the rest of the OS on the other drive. This way, if your boot/root disk dies, your important data is saved. If your array has problems, the boot/root disk provides the tools to fix it. - you can back up your boot/root drive with something like Mondo http://www.mondorescue.com/. Make that backup to CD, and when you need it, just put the CD in the drive, boot from it, and restore your system in whole or in part. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
