Hello Stefan,<div><br></div><div>Yes, there was a major change in the SOURCE attribute between the versions you mention. The current LVM drivers don't support SOURCE the way you are using them, since the expect a specific format for the SOURCE and your example "/dev/vg_cloud/execnode" doesn't work since it doesn't match that format.</div>
<div><br></div><div>The correct way to use them is:</div><div>1) You have a local file in your frontend that holds the image, let's say ubuntu.img</div><div>2) you register an image "oneimage create ubuntu.one -d <lvm_ds_id>". Inside ubuntu.one you'll have PATH=/path/to/ubuntu.img (and NOT source)</div>
<div>3) after the image create is performed you can use it as a regular image (use it inside the template as IMAGE_ID = ...)</div><div><br></div><div>This means that all the LVs you already have in your host can't be used unless they've been created by the "oneimage create". If this is a major problem and a drawback, let us know and we can think about how to support your preeexisting images defined with your own SOURCE and not with PATH, by changing the tm/iscsi drivers.</div>

<br>
I upgraded my installation from ONE 3.2 -> 3.6 with running virtual<br>
machines without trouble, but I am facing some problems with the new LVM<br>
datastore. I have some hosts with LVM (no CLVM!) and the volume group<br>
vg_cloud.<br>
<br>
Creating the datastore works without problems. The image is already on<br>
the host in a logical volume. I can register the image with the SOURCE<br>
attribute pointing to the path: /dev/vg_cloud/execnode<br>
<br>
If I try to instantiate the image, ONE creates a wrong path to clone the<br>
image:<br>

<br>
I created the datastore with the following configfile:<br>
NAME = LVMHOST<br>
DS_MAD = lvm<br>
TM_MAD = lvm<br>
VG_NAME = vg_cloud<br>
HOST = host03<br>
<br>
I tried to create the datastore with the DISK_TYPE attribute, but this<br>
did not help.<br>
<br>
Image with the source attribute:<br>
SOURCE = "/dev/vg_cloud/execnode"<br>
<br>
I am at the moment stuck at this point, in the old installation this<br>
worked without problems.<br>
<br>
