Correct, I am looking at ZFS as a potential VxVM/UFS replacement for this solution. > The first issue is how you get the > physical storage shared -- perhaps you zone (in SAN terms) the LUN to > multiple machines and rely on the hosts to sort out access. We already use VxVM on top of SRDF. We would plan on using ZFS on top of SRDF to handle replication instead of doing failover with both nodes accessing the same set of LUNs. > In any case, > as I see it your ZFS plans have to isolate the datasets for a failover > group (perhaps a particular zone) into a particular zpool.

Replacing the well-tested VxVM/UFS with ZFS is not something that I would do lightly and especially not outside of the supported configurations. I am very happy to hear about the upcoming agent.
