Can I use ZFS to create a multinode storage area. Multiple HDD's in

At least in theory you could use geom_gate and zfs I suppose, never
tried it though.
ggatec(8), ggated(8) are your friends for that.

Indeed, you can. I've done it. As for failover, you could run the
recently-committed HAST code on primary and backup central machines.
Upon failure of the primary central machine, the backup one would take
its IP address, mount the ZFS filesystem over the network, do whatever
other userspace things may be necessary, and resume servicing I/O.
