I wanted to provide some redundancy for the filesystems, but we're working on a limited budget and probably can't go for hardware RAID. I was envisioning using ccd to stripe and mirror (we'd like a speedup as well as redundancy) all the non-root filesystems and having 2 identical root filesystems on 2 different disks, with the one in use being dd'ed or dumped to the other one nightly. The duplicate would be left unmounted when not in use. Is vinum to the point where I should use it instead? I've yet to actually use ccd, any caveats? Would it be possible to handle things in such a way that if a non-root disk dies, the system continues to run, or at least reboots unattended and comes up working? What about a root disk? If some amount of coding would be required, I'm up to it, but I'm not intimately familiar with FreeBSD's innards. Is there a cheap RAID solution that works well?
