I've just run 'neutron net-list' on the undercloud node and I have the 2 networks, ctlplane and external.

My belief was that I don't need the external network, I only need the provision (ctlplane) network for the deployment.

I don't have a DHCP server for my external network.

Do I need to set the external IP address for the compute node and for the controller node in the yaml files from templates folder?

Thanks,

Anda

Hi Anda,

some things you could check:

Do you have 2 networks on director (ctlplane and external) and are they reachable from the overcloud nodes?

Seems to me that you have network issues and that's because you're seeing those long timeouts.

For "Message: No valid host was found. There are not enough hosts available" message you could check "/var/log/nova/nova-conductor.log".

Regards

I've let the deployment run overnight and it failed after almost 4hrs with the errors below. Do you happen to know the config file where I can decrease the timeout? I looked in /etc/nova/nova.conf and in ironic config files but I couldn't find anything relevant.

The errors are:

[overcloud.Compute.0]: CREATE_FAILED  ResourceInError: resources[0].resources.NovaCompute: Went to status ERROR due to "Message: Unknown, Code: Unknown"
[overcloud.Controller.0]: CREATE_FAILED  Resource CREATE failed: ResourceInError: resources.Controller: Went to status ERROR due to "Message: No valid host was found. There are not enough hosts available., Code: 500"

It is unclear to me why the above errors occur, since in my instackenv.json I declared node capabilities for both the computer and the controller node to be greater than the compute and controller flavors from 'openstack flavor list'.

However, I've found this link and I am looking over it:
https://docs.openstack.org/ironic/latest/admin/troubleshooting.html#nova-returns-no-valid-host-was-found-error

Thanks,
Anda

Check also network settings. 4h timeout is the default when something is unreachable.
