I'd go for individual volumes, might give you extra flexibility in the
future and it's also better security to have stuff in different places.

We use RAID6 in our setup, JBOD might give you better total throughput at
the cost of more hassle (replacing bricks). There was a similar thread

You can use a VIP to export your NFS, we use keepalived, but in hindsight I
regret not knowing about CTDB at the time, it plays well with Samba.
