Whats the better way depends of your needs, if you can afford to lose
"some" data use ZFS replication with something like zrep, otherwise I
would you with ZFS + iSCSI (which is what I use in production here), but
be very careful with "automatic failover". =20

If it can help this is what I use for my failover script:=20

(it relies extensively on CARP, so be sure to choose good NICs)
