Robert, and others,

I read this email too late to attend this.

I work on Sun's cluster product, where we provide a highly-available
NFS server (HA-NFS).  Our HA-NFS and our cluster product rely on
a model of multi-hosted disks, that is, each disk is connected
to more than one host.  Such that if one host dies, a suriviving
host can take over.

I believe that the model of replication and migration that you
folks have in mind is more general, and does not assume 
multi-hosted disks.

I would like to somehow be involved (or at least listen in)
on your design conversations, to try to be aware of any
issues where what you are doing may actively interfere
with a multi-hosted disk failover model.

Also, one topic I would like to better understand is state
preservation.

thanks,
