Open Stack

And I opened one 3 weeks ago!  :)  Just marked the one you did as a duplicate – happy to have it go either way though, no worries.

The error message is confusing, largely because the variable names are confusing, I suspect.  Anyway, there should be some fixes here for sure, and we probably want a way to do some more robust checking.  Basically the issue is that if you fail for any sort of hard limit right now (CPUs, RAM, instance count) it will give the same error message.  If we fix up that error message to give the actual numbers, its still not quite right because it could be for something other than the instance count.

Hey Jay,

I'm seeing the same incorrect messaging. From what I've observed, this happens when you exceed your quota. The failure is right but the message is wrong. I opened a bug for this last week.

CC: [Openstack] Quotas... 1 of 1 instances? What's the deal?


Hi Kevin, Stackers,

In Horizon, my tenant/user clearly says that 10 instances is my quota,
and yet trying to create a single server I'm getting this:

jpipes at uberbox:~/repos/tempest$ nosetests -v --nologcapture
======================================================================

     return self.request('POST', url, headers, body)

205, in request
     raise exceptions.OverLimit(resp_body['overLimit']['message'])
OverLimit: Quota exceeded
Details: Quota exceeded: already used 1 of 1 instances

But there are no instances at all on the box:

jpipes at uberbox:~/repos/tempest$ virsh list --all
  Id Name                 State
----------------------------------

When I check the DB, though, I've seeing the following:

mysql> select project_id, in_use, reserved, until_refresh from
quota_usages where resource = 'instances';
+----------------------------------+--------+----------+---------------+
| project_id                       | in_use | reserved | until_refresh |
+----------------------------------+--------+----------+---------------+

| f0c72dea9fda459aac64de460300e1ec |      0 |        2 |          NULL |
+----------------------------------+--------+----------+---------------+
2 rows in set (0.00 sec)

What's the deal here? Tempest needs to create and delete servers in
rapid succession, and it seems the reservation system might not be able
to keep up?

At a minimum, I think that the OverLimit: "Quota exceeded: already used
1 of 1 instances" message should be updated to not be so obviously wrong
with regard to the value of the resource quota itself?

Thanks,
-jay
