You know you can always take your existing setup and stick a ZFS/NFS head server off it on both ends, which can be physical or virtual.
You already invested time to get drbd+iet working seems ashame to throw it out. You just need to have the volume appear on the other end when the primary goes down with an auto-import, which will automatically export your NFS shares on import. Or if it isn't geographically separate use ZFS mirrors to each iSCSI host. -Ross On Mar 11, 2010, at 11:10 AM, Anton Altaparmakov <aia21 at cam.ac.uk> wrote: > Dear Steve, > > Thank you very much for the quick reply! > > On 11 Mar 2010, at 15:08, Steve Mckinty wrote: >> You can't do this with AVS within a single cluster. > > Ah! > >> You can setup two single-node clusters in a Geo Cluster configuration >> and configure AVS replication between the two "sites". > > Right, that sounds like what we want.
