What I would like to know with this post is 1.) whether there exists the ability to setup an analogue of this in FreeBSD; 2.) how this would be done if it is possible; 3.) whether the capabilities of this in FreeBSD are sufficiently mature to manage it; and 4.) how worst-case recovery scenarios would go on FreeBSD. I have a four disk software RAID setup in Linux. Everything is in RAID with the exception of swap. Here's an approximation of my setup: /dev/sd{a,b,c}1 is in a RAID 1 array used as /boot. /dev/sd{a,b,c}2 is in a RAID 1 array used a /root. /dev/sd{a,b,c}3 is used as swap with each of equal priority. /dev/sd{a,b,c}4 is in a RAID 5 array used as LVM. /dev/sdd houses spare partitions for the compliment supra. LVM is henceforth broke up according to proper Linux-FHS rules. What are your thoughts on this? Cheers, Matt
