OK, vinum is good. But my understanding is that you can't use vinum on your root partition. By Murphy's Law it always seems to be root that gets screwed up. And that also causes the biggest problems because then you have to yank the system apart and find another host disk for booting.
What about "duplicating and updating" /, /var and /usr onto a 2nd disk ? This could be automatically done by a shellscript. You only need to fine tune /mirror/etc/fstab to boot from the correct disk after a such a "backup/mirror" run ....
If you install the freebsd boot manager you can even easily test booting from the 2nd drive without having to make special settings in the forth boot loader.
You could manage this using three disks I think
Disk: da0 da1 da2 Fs: ================================================================+ root-fs | s1a s1a (backup) | | ------------------------------------------------+ | swap | swap swap | | ------------------------------------------------+ swap | var-fs | s1f s1f (backup) | | ------------------------------------------------+ | usr-fs | s1g s1g (backup) | | ------------------------------------------------+---------------+ vinum RAID5 | /usr/local | ------------------------------------------------+---------------+ vinum RAID5 | /home | ------------------------------------------------+---------------+
I'm not sure, maybe its even possible to put /var onto a Vinum Software RAID-5 ......
