Title:
Creating a volume from an instance snapshot should validate the volume
size / min_disk
Status in OpenStack Dashboard (Horizon):
Fix Committed
Status in OpenStack Dashboard (Horizon) icehouse series:
In Progress
Bug description:
This is sort of a follow-up to bug 1241253. When an image is created
based on an instance snapshot, even though the same min_disk
restrictions apply, they're not reflected properly in the validation
and tool tips, resulting in misleading information being shown to the
user.
Steps to reproduce:
-------------------------
1. Create an image with a minimum disk size of e.g. 2GB
2. Boot an instance from the image
3. Create a snapshot of the instance (from dashboard or using nova
create-image)
4. Back on the images panels, click the "Create volume" button for the new
image
5. The prefilled size and size tooltip do not indicate the correct minimum
disk size
This seems to be happening because in that case the min_disk attribute is set
as a property rather than a direct attribute, looking at Glance:
$ glance image-show <id_of_image>
+------------------+--------------------------------------+
| Property | Value |
+------------------+--------------------------------------+
...
| min_disk | 2 |
...
$ glance image-show <id_of_instance_snapshot>
+---------------------------------+------------------------+
| Property | Value |
+---------------------------------+------------------------+
...
| Property 'min_disk' | 2 |
...
| min_disk | 0 |
...
I'm not sure why... Maybe someone from Glance could shed some light on
this and whether that's the expected behaviour?
In the meantime it shouldn't be too hard for Horizon to handle the
case where min_disk is set as a property.
