Description Marius Cornea 2017-11-22 04:48:22 EST

Description of problem:
OSP11 -> OSP12 upgrade: when UpgradeRemoveUnusedPackages is set to true the upgrade-non-controller.sh fails with expected string or buffer

Version-Release number of selected component (if applicable):
openstack-tripleo-heat-templates-7.0.3-10.el7ost.noarch

How reproducible:
100%

Steps to Reproduce:
1. Deploy OSP11 with 1 controller + 1 compute
2. When upgrading set UpgradeRemoveUnusedPackages to true 
3. Run major-upgrade-composable-steps-docker.yaml
4. Run upgrade-non-controller.sh --upgrade compute-0

Actual results:

(undercloud) [stack@undercloud-0 ~]$ upgrade-non-controller.sh --upgrade compute-0
Wed Nov 22 04:36:00 EST 2017 upgrade-non-controller.sh Logging to upgrade-non-controller.sh-compute-0
Wed Nov 22 04:36:04 EST 2017 upgrade-non-controller.sh nova node compute-0 found with IP 192.168.24.16 
Wed Nov 22 04:36:04 EST 2017 upgrade-non-controller.sh Executing /root/tripleo_upgrade_node.sh on 192.168.24.16

Wed Nov 22 04:36:04 EST 2017 upgrade-non-controller.sh Clearing any existing dir compute-0 and downloading config
expected string or buffer

Expected results:
The compute node gets upgraded without errors.

Comment 1 Marios Andreou 2017-11-22 11:32:58 EST

this looks to be a regression in openstack overcloud config download:

(undercloud) [stack@undercloud-0 MARIOS]$   openstack overcloud config download --config-dir "$UPGRADE_NODE"             
expected string or buffer

The error is happening here https://github.com/openstack/tripleo-common/blob/9f5e38e7d398c60af4d165943417dbde70639d53/scripts/upgrade-non-controller.sh#L182 during the upgrade-non-controller run, but the error comes from config download itself
