You expect too much of my RAID controller. :) Ghost won't do it because: 1. There is only room for 3 drives in the system. RAID5 requires 3 drives. 2. Ghost deals in partitions. FreeBSD (usually) has one partition with many slices. 3. Doubt it has drivers for my RAID array. :) On Fri, 10 Jun 2005, Alex Zbyslaw wrote: > Tony Shadwick wrote: > >> >> I have a system that we are running in production that there was an >> oversight on, and it has a single hard drive installed (32GB SCSI I >> believe), rather than a 3 drive raid5 array.
