Hi,
just hit the issue:
openstack volume create --bootable --image cirros --size 5 cird
openstack volume snapshot create --volume
7f3278c2-eb86-44e1-871a-464eb7f1bdf1 snapcird
openstack volume create --bootable --snapshot snapcird --size 7 volcird
at the moment:
# 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 |
+--------------------------------------+---------+----------+------+-------------------------------+
but later becomes to error state with to the following message in cinder
log:
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
Possible something related to similar naming? Note, that CV_c1245... and
CV_c1245 have exactly the same "LV Thin origin name":
