Description Alexander Chuzhoy 2016-07-08 20:05:16 UTC
rhel-osp-director:  8.0->9.0 upgrade, Keystone WSGI migration step fails, httpd resource is down on the cluster and fails to start.


Steps to reproduce:
1. Deploy 8.0 with:
openstack overcloud deploy --templates --control-scale 3 --compute-scale 1   --neutron-network-type vxlan --neutron-tunnel-types vxlan  --ntp-server --timeout 90 -e /usr/share/openstack-tripleo-heat-templates/environments/storage-environment.yaml -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml -e network-environment.yaml --ceph-storage-scale 1

2. Upgrade the undercloud 
3. Successfully pass the step with "-e /usr/share/openstack-tripleo-heat-templates/environments/major-upgrade-aodh.yaml"
4. Attempt to do the keystone wsgi migration step (includes  -e /usr/share/openstack-tripleo-heat-templates/environments/major-upgrade-keystone-liberty-mitaka.yaml)

Stack overcloud UPDATE_FAILED
Deployment failed:  Heat Stack update failed.

Checked the pcs resource status. Several resources were stopped.
ran "pcs resource cleanup"
All but one resource successfully started. 

[root@overcloud-controller-1 ~]# pcs status|grep -B1 -i stop
 Clone Set: httpd-clone [httpd]
     Stopped: [ overcloud-controller-0 overcloud-controller-1 overcloud-controller-2 ]

Was unable to start this resource:
(98)Address already in use: AH00072: make_sock: could not bind to address

turned out "/usr/bin/python2/usr/bin/keystone-all" was already using port 5000.

Comment 2 Alexander Chuzhoy 2016-07-08 20:33:25 UTC
The workaround is to stop the openstack-keystone.service on all controllers and then to start the httpd resource.
