Not today. We are very early on in the process of defining a project to
make ZFS a shared file system for Sun Cluster. When this project is
complete (no idea when that might be, yet, sorry), it will be possible
to share a zpool among nodes of a cluster.
We have support for fail-over ZFS (HA-ZFS) in the next release of Sun
Cluster, due out later this year. That doesn't provide concurrent
access, but it does provide high availability.
This simply means that the Query server will have readonly access to
the data (no lock manage required as far as I can tell), so that is why
I would need to import the storage pool readonly or at least without
exporting it.
It's conceivable that it might work if *all* the nodes imported the pool
read-only, but that's not tested and certainly not supported.
