Unfortunately, VxFS is still the best way to go with Veritas Cluster in
a HA environment -- ZFS cannot go active-active with the same filesystem
on two nodes.
Since you mentioned DR, you can use VVR and go
(active-active)<-VVR->(active-active) and write to the "same" filesystem
on four nodes (assuming synchronous locking doesn't bottleneck your I/O).
ZFS is good stuff but it can't replace VxFS/VVR (yet). VxFS has a few
years head-start. :)
