<p>Hi,</p>
<p>just hit the issue:</p>
<p>openstack volume create --bootable --image cirros --size 5 cird<br>
openstack volume snapshot create --volume
7f3278c2-eb86-44e1-871a-464eb7f1bdf1 snapcird<br>
openstack volume create --bootable --snapshot snapcird --size 7
volcird</p>
<p>at the moment:</p>
<pre># openstack volume list
+--------------------------------------+---------+----------+------+-------------------------------+
| ID | Name | Status | Size | Attached to |
+--------------------------------------+---------+----------+------+-------------------------------+
| 4cc883df-5c1c-431e-bc8e-f0f228593b0b | volcird | creating | 7 | |
| 7f3278c2-eb86-44e1-871a-464eb7f1bdf1 | cird | in-use | 5 | Attached to cir4 on /dev/vda |
+--------------------------------------+---------+----------+------+-------------------------------+
</pre>
<p>but later becomes to error state with to the following message in
cinder log:</p>
<p>linstor.errors.LinstorError: Error: Could not resource definition
'CV_4cc883df-5c1c-431e-bc8e-f0f228593b0b' for snapshot restore:
The creation of a new resource definition failed due to a name
collision</p>
<p>Possible something related to similar naming? Note, that
CV_c1245... and CV_c1245 have exactly the same "LV Thin origin
name":<br>
