Hi,<div><br></div><div>I'm sure if I understand everything but let me give a try.</div><div>By default, the compute nodes store virtual instances in /var/lib/nova/instances/. Of course it's part of the compute node local FS. If you want to store this directory somewhere else, use a DFS like GlusterFS or even Ceph or a SAN.</div>
<div>Also don't forget that you <b>can't </b>use Swift for storing your virtual instances.<br><br>Hope it is what you asked for.<br><br>Cheers.<br><br><div class="gmail_quote">On Thu, Jun 28, 2012 at 1:48 AM, udit agarwal <span dir="ltr"><<a href="mailto:fzdudit@gmail.com" target="_blank">fzdudit@gmail.com</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br> I have set up Openstack in my lab with everything except storage nodes on one system and two other systems with each of them acting themselves as a storage node. I have used swift as the backend for glance so all the uploaded images are stored on these storage nodes. But when I run a virtual machine using nova, it reads the image from the storage nodes and it seems to me that it uses the local filesystem for storing instances and after I shutoff my virtual machine, it writes back to the storage nodes. But the thing that I want to implement is that if I copy some file from my local system to that virtual machine, it should automatically get stored on my storage nodes rather than occupying space on my local filesystem. <br>
<br> Can anybody help me with this?? <br> Thanks in advance.<span class="HOEnZb"><font color="#888888"><br><br>--Udit Agarwal<br>
