so, this has to be done offline via a boot disk for /var.<br>

<div>That's exactly as I thought :)</div>
<div> </div>
<div>For now, a safer way around this, I moved the /var/lib/xend/saved folder to it's own LVM volume, and re-mounted it on /var/lib/xend.</div>
<div> </div>
<div>So now /var has 1.4GB free space from 2GB</div>
