You're trying to lower performance of VM system? If swap is not mirrored, and this disk dies, the system will crash. If everything is mirrored, the system can be brought down for maintenance in a regularly scheduled window rather than crashing immediately. Even better is if the disks are hot swappable, the system never needs to go down at all with a disk failure. -- jeff@jeffenstein.org http://www.jeffenstein.org/ It's the opinion of some that crops could be grown on the moon. Which raises the fear that it may not be long before we're paying somebody not to. -- Franklin P.
