environments/hyperconverged-ceph.yaml fails with Error validating value 'storage_mgmt': Unable to find network with name or id 'storage_mgmt'

[John Fulton]

As of Pike, when a deployment uses -e /usr/share/openstack-tripleo-heat-templates/environments/hyperconverged-ceph.yaml it fails with:

017-11-02 00:40:28Z [overcloud.Compute]: CREATE_FAILED resources.Compute: resources.StorageMgmtPort: resources[2].Property error: resource
s.StorageMgmtPort.properties.network: Error validating value 'storage_mgmt': Unable to find network with name or id 'storage_mgmt'
2017-11-02 00:40:28Z [overcloud.Controller]: CREATE_FAILED CREATE aborted
2017-11-02 00:40:28Z [overcloud]: CREATE_FAILED Resource CREATE failed: resources.Compute: resources.StorageMgmtPort: resources[2].Property
 error: resources.StorageMgmtPort.properties.network: Error validating value 'storage_mgmt': Unable to find network with name or id 'storage
_mgmt'

This happens because environments/hyperconverged-ceph.yaml references network/ports/storage_mgmt.yaml [1], but starting in Pike, network/ports/storage_mgmt.yaml removed because it would instead be rendered by the changes introduced with composable networks.

The environments/hyperconverged-ceph.yaml file was only introduced to make it easier for users to deploy HCI without having to compose their own roles, which could be error prone. Instead they would just add "-e environments/hyperconverged-ceph.yaml" to their "openstack overcloud deploy ... " command.

However, starting in Pike there is an alternative method to deploy HCI without having to edit roles files. I will post that two step process in my next update to this bug.

Instead of using "-e environments/hyperconverged-ceph.yaml" use the new "openstack overcloud role" make a Compute HCI role along with the other roles that are being deployed. E.g. If you're deploying Controllers and ComputeHCI then do the following:

 openstack overcloud roles generate -o roles_data.yaml Controller ComputeHCI

The above will generate a roles_data.yaml for you and then you just need to include it in your deployment with "-r roles_data.yaml".

Note that `openstack overcloud role list` lists computeHCI along with other available roles. See https://docs.openstack.org/tripleo-docs/latest/install/advanced_deployment/custom_roles.html#provided-example-roles

I think storage_mgmt.yaml is generated from the jinja template and uploaded into swift before the deployment starts, the reason why the file doesn't exist is that the Compute role doesn't have the StorageMgmt network enabled, only ComputeHCI has

Unfortunately I don't think there is a simple method to make an environment file enable a role nor I think we want people to enable StorageMgmt on the Compute role... we should probably simply deprecate the environment file and update references in the docs.

    Deprecate hyperconverged-ceph.yaml

    This file was introduced in Newton to allow for HCI deployments
    without requiring the user to edit roles_data.yaml. However, a
    more general solution exists to use composable roles without
    manually editing roles_data.yaml. This change adds a comment
    describing how to use the new method instead.
