Description Udi 2016-03-24 16:41:22 UTC
Description of problem:
When using the static IP allocation feature, no validations are run to see if there are enough IPs in the pool for the requested number of nodes. The deployment simply hangs until it times out.


Version-Release number of selected component (if applicable):
python-tripleoclient-0.3.1-1.el7ost.noarch
openstack-tripleo-heat-templates-0.8.12-1.el7ost.noarch


How reproducible:
100 %


Steps to Reproduce:
1. In your environment file, create an IP pool for the compute nodes, but make sure you won't have enough for them all. In this example there is only 1 IP:

parameter_defaults:
  NovaComputeIPs:
    internal_api:
      - 10.35.191.100

2. Deploy with more nodes than the pool size


Actual results:
Deployment hangs


Expected results:
User should get a clear error right on the beginning of the deployment, that more IPs are needed in the pool. Deployment should be aborted and not even attempted.

This bug did not make the OSP 8.0 release.  It is being deferred to OSP 10.

While I think this BZ would be good to address, I think the fact that you need to have sufficient IP space in your allocation pools is well documented. I changed the topic of this BZ to indicate that is a feature request.

I think this is best addressed with an addition to the tripleo-validations. I have added this BZ to the list of future enhancements to networking validations in tripleo-validations.

I am setting the target to OSP 11 for now, although it isn't yet clear if this particular enhancement will be able to land in Ocata.
