Thank you.<div>From the explanation, it seems to require the VM instance working directory to be physically in the same place of $ONE_LOCATION/var, even though the nodes can mount it at a different location using NFS. </div>
<div><br></div><div>I have a few comments</div><div>1. Mounting the same disk at different locations on different machines does not really make much sense to me, although perfectly possible. So I find this not a critical feature. This is what I think VM_DIR is designed for and in this sense, the current code works perfectly fine.</div>
<div>2. However, in my plan, I want to put the VM instance working directory (thus VM_DIR) to be a different physical LUN than the $ONE_LOCATION/var since I would like to implement different storage features on $VM_DIR and $ONE_LOCATION. For example, they can have different backup and snapshot setups. $ONE_LOCATION is more critical and I might want to implement hourly snapshot/backup while $VM_DIR is for working image files and I might only want to do it daily considering the amount of storage required and the consistency of snapshotting a disk image under use. </div>
<div>This is how I thought the definition of VM_DIR can be of more value.</div><div><br></div><div>Thanks.</div><div>Shi</div><div><br><br><div class="gmail_quote">On Thu, Feb 24, 2011 at 6:59 AM, Javier Fontan <span dir="ltr"><<a href="mailto:jfontan@gmail.com">jfontan@gmail.com</a>></span> wrote:<br>
