A few things here:

- openstack_dashboard/dashboards/project/volumes/templates/volumes/_create_snapshot.html still references _quotas.html instead of _limits.html
- the CreateSnapshotView still references tenant_quote_usages instead of absolute_limits
- however it doesn't look like cinder's absolute limits return the current usage, only the max allowed? We may need to stick to quotas for now, and revert the _quotas template to what it used to be (currently _limits.html references variable such as usages.gigabytesUsed that do not exist, as far as I can tell)

Hi Nuno Santos, will you be pushing a corrected fix for this bug? The snapshot limit/quota is not used in your current patch, I have fixed this issue in my environment, I can share the fixed patch with you, Or if you are not working on this bug then i can push a new review to fix this issue.

I am hitting a similar issue using the Netapp driver for nfs and iscsi except all snapshots from the horizon gui fail whether they were created from an image or not.

[Julie Pichon (jpichon)]

I will propose a patch that fixes the template and quota/limit issues, and attempts to address the comments made on the previous reviews notably about centralised quotas in the one file. The centralisation was somewhat lost during the move from quotas to limits and the result is a bit confusing -- I filed bug 1227169 to address a future refactoring separately (probably for Icehouse).

    Fix volume snapshot creation

    The referenced template was wrong, and the quota usages information
    had not been switched to using limits.

    Thanks to Nuno Santos and Rohan Kanade for the initial versions of
    this patch.
