<br>
I followed your steps, but they are not working for me.<br>
I put the raw image in /scratch/execnode.img and created a template for<br>
it with the PATH attribute. I did this on host01, my front end with oned<br>
running etc.<br>
I registered the image and ONE created a LV on host03, one of my LVM<br>
host, see logs below.<br>
But the image was not dumped with dd into the LV and therefore the<br>
virtual machine came up without a disk.<br>
<br>
I had a look into the LVM datastore scripts and the DUMP is not executed<br>
on the CP event. They should work without problems with just LVM and not<br>
CLVM.<br>
<br>
Regards,<br>
Stefan<br>
