PXE boot nodes on an overcloud deploy end up at a dracut prompt.
Environment
Red Hat Enterprise Linux OpenStack Platform (RHEL-OSP) 7.0
Issue
When trying to deploy a new overcloud deployment over an existing installation, discovery images end up at a dracut prompt and never deploy properly.
Resolution
Delete nodes on undercloud in Ironic using:
#ironic node-delete <uuid of node>
Manually remove discovered.sqlite:
#rm /var/lib/ironic-discoverd/discoverd.sqlite
Restart openstack-ironic-discoverd to repopulate the initial database:
#systemctl restart openstack-ironic-discoverd
After completing the steps above run through registering the nodes, running introspection against the nodes and attempt another deployment of the overcloud. If you need further assistance on these steps please see the following guide: Red Hat Enterprise Linux OpenStack Platform 7.0 Director Installation and Usage
Root Cause
Client was trying to deploy but had misconfiguration of network initially after a successful deployment. Client made network configuration changes and then tried a redeploy which ended up in the resulting dracut prompt on a PXE boot.
