<div>Hi, </div><div>I have been trying Open Nebula for a couple of weeks now and so far it works great, one of the complex steps of building the cloud is the storage. After reading about LVM on the website and then from the mailing list I managed to get it working , VG_NAME=/images, and now I can instance many virtual machines to the pool within seconds or minutes without having to clone (wasting storage) the images or wasting bandwidth transferring from the front end to the nodes. </div>
<div>Now the problem I am facing is that the lvm/tm_delete.sh script can't manage to delete the snapshots created by lvm/clone.sh. I have tried onevm $ID delete,shutdown and cancel as recommended in a previous thread but none of them worked.</div>
<div>This is the log output: </div><div><br></div><div><div><div>Wed Sep 1 16:20:47 2010 [InM][I]: Monitoring host 192.168.1.4 (5)</div><div>Wed Sep 1 16:20:47 2010 [VMM][D]: Message received: LOG - 62 Driver command for 62 cancelled</div>

<br></div><div>After checking the script tm_delete.sh I see everything is fine , so I don't understand why instead of /dev/images one is looking for /images/.</div><div><br></div><div>Italo</div>
