We are trying to install Openstack 13 on 3 node setup as mentioned below

Director Node Proliant DL360 Gen9 CPU:8 Memory:16 Disk: 136GB Controller Node Dell PowerEdge R730xd CPU:8 Memory:128 Disk: 111GB Compute Node Proliant DL350P Gen8 CPU:6 Memory:48 Disk: 146GB

Undercloud is successfully Installed.

Overcloud deployment is failing again and again with below 3 different errors.

1)Unable to import overcloud images into the director

(undercloud) [stack@director ~]$ openstack overcloud image upload --image-path /home/stack/images/

(undercloud) [stack@director ~]$ openstack image list
Service Unavailable (HTTP 503)

2)Unable to restart openstack-glance-api.service

Configuration has 8 errors, fix them before proceeding. Ignoring these errors is likely to lead to a failed deploy.
