Description Ryan Wyse 2016-10-21 18:05:15 UTC 
Description of problem:

The network-environment.yaml has an external network that is a vlan that is being used for Admin purposes.  In the file the vlan id is set to 30, the CIDR is 10.75.106.64/26, the gateway is 10.75.106.65, and the allocation pool is set to start=10.75.106.83,end=10.75.106.120.  Neutron subnet-show shows this all as expected.  

When the deploy was kicked off neutron ports were created for all the addresses in the range except 10.75.106.96-10.75.106.101.  These addresses don't have IP issues on the network and are not assigned anywhere else either, yet not only are the ports not created, but during a scaling operation we were getting no more addresses available errors and failure.

Version-Release number of selected component (if applicable):
RHEL OSP 8.0

How reproducible:


Steps to Reproduce:
1.  
2.
3.

Actual results:
Scale failure due to no more addresses available and network configuration failure on some of the compute nodes.

Expected results:
Ports to have been created and available IP addresses to have been assigned to the compute nodes.

Comment 1 Dan Sneddon 2016-10-21 18:24:41 UTC 
Please provide some additional information:

neutron subnet-show <UUID>  (where UUID is obtained with "neutron subnet-list")
neutron port-list

Both of these commands should be run after running "source ~stack/stackrc"

Revisiting this... The referenced ticket is no longer available, but as this is a scaling issue it may be the situation described here - http://post-office.corp.redhat.com/archives/rhos-prio-list/2017-June/msg00014.html

When nodes are deleted and re-added the IP addresses are not reclaimed as the index for the IP addresses are monotonically increasing.  In that case additional addresses need to be added to the pool to accommodate nodes that were deleted.

Please indicate if this is the issue you are hitting.  Thank you.
