I'm pretty sure there is nothing wrong with the LVM partitioning - I<br>
am using the same partitioning/methods on a older (ubuntu 10.04)<br>
server.<br>
<br>
Just a note it is a Ubuntu 12.04 server that has the issue...<br>

Still getting the same thing<br>
<br>
Any ideas how to troubleshoot this further ?<br>
