Thanks for the update Anand.
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.

We made good progress with unfs3 integration using booster model.
GlusterFS
and unfs3 (modified version) will run in single address space using
booster library.
This feature is scheduled for 2.1. We will try to have a pre-release
available
soon (in weeks). GlusterFS v2.2 will have a native NFS protocol
translator.
iSCSI exporting requires mmap support. You can create image files
and losetup them
as devices. Then it will be possible to export as iSCSI volumes. We
just fixed
a bug that caused poor mmap write performance. Work is on the way.
We will keep
you updated.

Jonathan,
You can export a Gluster mount via a client with a NFS server
however the performance is pretty poor. As far as i know there
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!
