Funny you mention unfs3.  Just today one of our engineers at work setup 
unfs3 against our large production gluster cluster and, so far, it has 
been very good.  I just was reading up on your modified booster version 
and will also give that a try also.

I'm looking forward to testing out the modified unfs3 and the native nfs 
protocol translator!

I'd suggest waiting till Jun 23-24 for 2.0.3 to come out. That has all 
the improvements/fixes to booster and libglusterfsclient, in order

to get unfs3 to work properly.

 You can export a Gluster mount via a client with a NFS server

is no way to export it with iSCSI.
 Your best option is to use a single/dual Linux/Solaris iscsi
server to boot strap all your systems in xenServer and then use
Gluster and fuse to mount your /data drive once the system is up
and running.

   Hi all,

   I am attempting to prevent my company from having to buy a SAN to
   backend our virtualization platform(xenServer). Right now we
have a
   light workload and 4 dell 2950's (6disks, 1 controller each) to
   leverage against the storage side. I like what I see in regard to
   the "Distributed Replicated Storage" where you essentially
create a
   RAID 10 of bricks. This would work very well for me. The question
   is, how do I serve this storage paradigm to a front end that's
   expecting an NFS share or an iSCSI target? Does gluster
enable me to
   access the entire cluster from a single IP? Or is it something I
   could run on a centos cluster (luci and ricci) and use the
cluster
   suite to present the glustered file system in the form of an
NFS share?

   Let me back up and state my needs/assumptions:

   * A storage cluster with the capacity equal to at least 1
   node(assuming all nodes are the same).

   * I need to be able to lose/take down any one brick in the
cluster
   at any time without a loss of data.

   * I need more than the throughput of a single server, if not in
   overall speed, then in width.

   * I need to be able to add more bricks in and have the
expectation
   of increased storage capacity and throughput.

   * I need to present the storage as a single entity as an NFS
share
   or a iSCSI target.

   If there are any existing models out there please point me
too them,
   I don't mind doing the work I just don't want to re-invent the
   wheel. Thanks in advance for your time and effort, I know
what its
   like to have to answer newbie questions!

What are the more effective uses of gluster to backend virtualization. Any
