Re: [Gluster-users] Need a quick answer on Distributed Replicated Storage questions
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. liam On Mon, Jun 15, 2009 at 5:15 PM, Jonathan Bayles jbay...@readytechs.comwrote: Hi all, I am attempting to prevent my company from having to buy a SAN to backend our virtualization platform(xenServer).

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. -Shehjar Thanks! ls On Thu, Jun 18, 2009 at 1:36 AM, Anand Babu a...@gluster.com mailto:a...@gluster.com wrote: We made good progress with unfs3 integration using booster model.
