[one-users] ONE 3.6: Problem with LVM datastore

[Dietrich, Stefan]

Hello,

I upgraded my installation from ONE 3.2 -> 3.6 with running virtual
machines without trouble, but I am facing some problems with the new LVM
datastore. I have some hosts with LVM (no CLVM!) and the volume group
vg_cloud.

Creating the datastore works without problems. The image is already on
the host in a logical volume. I can register the image with the SOURCE
attribute pointing to the path: /dev/vg_cloud/execnode

If I try to instantiate the image, ONE creates a wrong path to clone the
image:

Error cloning /dev//dev/vg_cloud/execnode//dev/vg_cloud/execnode
to /dev//dev/vg_cloud/execnode//dev/vg_cloud/execnode-861-0

I created the datastore with the following configfile:
NAME = LVMHOST
DS_MAD = lvm
TM_MAD = lvm
VG_NAME = vg_cloud
HOST = host03

I tried to create the datastore with the DISK_TYPE attribute, but this
did not help.

Image with the source attribute:
SOURCE      = "/dev/vg_cloud/execnode"

I am at the moment stuck at this point, in the old installation this
worked without problems.

Regards,
Stefan
