In Part 2 of this two part series at Linux Journal, Joe Edwards, Audin Malmin and Ron Shaker introduce RAID-1. This installment features how to make a RAID-1 swap device and boot from a RAID-1 device, as well as how to use RAID-1 to facilitate disk backups . . .

“If you are using RAID-1 to help to ensure that your system stays up in the event of a hard disk partition failure, you should consider raiding your swap partition(s). If the disk or partition you are using for swap goes bad, your machine may crash. Using a RAID-1 device for a swap partition can help prevent that crash. If one of the mirrored swap partitions goes bad, the kernel automatically will fail over to the other, and your system should keep running until you can fix the disk problem . . . “
