My intent is to make the IDE drive a bootable (after BIOS change) system that is ready to go in the event of failure of a SCSI drive or controller. We will backup all the data a three times a day over to the IDE but keep this filesystem automonous so corruptions can't stop it from being bootable. It can be tossed into another compatible box instantly and remain immediately ready to run (this is why I was suspicious of vinum). Is this the best way to approach keeping nearly 0% downtime or does FreeBSD have a more elegant approach? BTW, we don't have a raid controller and this system seems too bleeding edge (hardware wise) already to attempt that. Thank you, Chris
