StarlingX/Installation Guide Virtual Environment/Controller Storage

Preparing Servers

Bare Metal

Required Servers:

  • Controllers: 2
  • Computes: 2 - 100

Hardware Requirements

The recommended minimum requirements for the physical servers where StarlingX Controller Storage will be deployed, include:

  • ‘Minimum’ Processor:
    • Dual-CPU Intel® Xeon® E5 26xx Family (SandyBridge) 8 cores/socket
  • Memory:
    • 64 GB Controller
    • 32 GB Compute
  • BIOS:
    • Hyper-Threading Tech: Enabled
    • Virtualization Technology: Enabled
    • VT for Directed I/O: Enabled
    • CPU Power and Performance Policy: Performance
    • CPU C State Control: Disabled
    • Plug & Play BMC Detection: Disabled
  • Primary Disk:
    • 500 GB SDD or NVMe Controller
    • 120 GB (min. 10K RPM) Compute
  • Additional Disks:
    • 1 or more 500 GB disks (min. 10K RPM) Compute
  • Network Ports*
    • Management: 10GE Controller, Compute
    • OAM: 10GE Controller
    • Data: n x 10GE Compute

Virtual Environment

Run the libvirt qemu setup scripts. Setting up virtualized OAM and Management networks:

$ bash setup_network.sh

Building xmls for definition of virtual servers:

$ bash setup_standard_controller.sh -i <starlingx iso image>

Accessing Virtual Server Consoles

The xml for virtual servers in stx-tools repo, deployment/libvirt, provides both graphical and text consoles.

Access the graphical console in virt-manager by right-click on the domain (the server) and selecting "Open".

Access the textual console with the command "virsh console $DOMAIN", where DOMAIN is the name of the server shown in virsh.

When booting the controller-0 for the first time, both the serial and graphical consoles will present the initial configuration menu for the cluster. One can select serial or graphical console for controller-0. For the other nodes however only serial is used, regardless of which option is selected.

Open the graphic console on all servers before powering them on to observe the boot device selection and PXI boot progress. Run "virsh console $DOMAIN" command promptly after power on to see the initial boot sequence which follows the boot device selection. One has a few seconds to do this.

Controller-0 Host Installation

Installing controller-0 involves initializing a host with software and then applying a bootstrap configuration from the command line. The configured bootstrapped host becomes Controller-0.
Procedure:

  1. Power on the server that will be controller-0 with the StarlingX ISO on a USB in a bootable USB slot.
  2. Configure the controller using the config_controller script.

Initializing Controller-0

This section describes how to initialize StarlingX in host Controller-0. Except where noted, all the commands must be executed from a console of the host.

Power on the host to be configured as Controller-0, with the StarlingX ISO on a USB in a bootable USB slot. Wait for the console to show the StarlingX ISO booting options:

  • Standard Controller Configuration
    • When the installer is loaded and the installer welcome screen appears in the Controller-0 host, select the type of installation "Standard Controller Configuration".
  • Graphical Console
    • Select the "Graphical Console" as the console to use during installation.
  • Standard Security Boot Profile
    • Select "Standard Security Boot Profile" as the Security Profile.


Monitor the initialization. When it is complete, a reboot is initiated on the Controller-0 host, briefly displays a GNU GRUB screen, and then boots automatically into the StarlingX image.
Log into Controller-0 as user wrsroot, with password wrsroot. The first time you log in as wrsroot, you are required to change your password. Enter the current password (wrsroot):

Changing password for wrsroot.
(current) UNIX Password:

Enter a new password for the wrsroot account:

New password:

Enter the new password again to confirm it:

Retype new password:

Controller-0 is initialized with StarlingX, and is ready for configuration.

Configuring Controller-0

This section describes how to perform the Controller-0 configuration interactively just to bootstrap system with minimum critical data. Except where noted, all the commands must be executed from the console of the active controller (here assumed to be controller-0).

When run interactively, the config_controller script presents a series of prompts for initial configuration of StarlingX:

  • For the Virtual Environment, you can accept all the default values immediately after ‘system date and time’.
  • For a Physical Deployment, answer the bootstrap configuration questions with answers applicable to your particular physical setup.


The script is used to configure the first controller in the StarlingX cluster as controller-0. The prompts are grouped by configuration area. To start the script interactively, use the following command with no parameters:

controller-0:~$ sudo config_controller
System Configuration
================
Enter ! at any prompt to abort...
...

Accept all the default values immediately after ‘system date and time’.

...
Applying configuration (this will take several minutes):

01/08: Creating bootstrap configuration ... DONE
02/08: Applying bootstrap manifest ... DONE
03/08: Persisting local configuration ... DONE
04/08: Populating initial system inventory ... DONE
05:08: Creating system configuration ... DONE
06:08: Applying controller manifest ... DONE
07:08: Finalize controller configuration ... DONE
08:08: Waiting for service activation ... DONE

Configuration was applied

Please complete any out of service commissioning steps with system commands and unlock controller to proceed.

After config_controller bootstrap configuration, REST API, CLI and Horizon interfaces are enabled on the controller-0 OAM IP Address. The remaining installation instructions will use the CLI.

Controller-0 and System Provision

On Controller-0, acquire Keystone administrative privileges:

controller-0:~$ source /etc/nova/openrc

Configuring Provider Networks at Installation

You must set up provider networks at installation so that you can attach data interfaces and unlock the compute nodes.

Set up one provider network of the vlan type, named providernet-a:

[wrsroot@controller-0 ~(keystone_admin)]$ neutron providernet-create providernet-a --type=vlan
[wrsroot@controller-0 ~(keystone_admin)]$ neutron providernet-range-create --name providernet-a-range1 --range 100-400 providernet-a

Configuring Cinder on Controller Disk

Review the available disk space and capacity and obtain the uuid of the physical disk

[wrsroot@controller-0 ~(keystone_admin)]$ system host-disk-list controller-0

Enable LVM Backend.

[wrsroot@controller-0 ~(keystone_admin)]$ system storage-backend-add lvm -s cinder --confirmed

Wait for the storage backend to leave "configuring" state. Confirm LVM Backend storage is configured:

+--------------------------------------+------------+---------+------------+------+----------+...

Unlocking Controller-0

You must unlock controller-0 so that you can use it to install the remaining hosts. On Controller-0, acquire Keystone administrative privileges. Use the system host-unlock command:

[wrsroot@controller-0 ~(keystone_admin)]$ system host-unlock controller-0

The host is rebooted. During the reboot, the command line is unavailable, and any ssh connections are dropped. To monitor the progress of the reboot, use the controller-0 console.

Verifying the Controller-0 Configuration

On Controller-0, acquire Keystone administrative privileges:

controller-0:~$ source /etc/nova/openrc

Verify that the StarlingX controller services are running:

[wrsroot@controller-0 ~(keystone_admin)]$ system service-list
+--------------------------------------+------------------+--------------+----------+---------+-------+ ...
| Id                                   | Binary           | Host         | Zone     | Status  | State | ...
+--------------------------------------+------------------+--------------+----------+---------+-------+ ...
| d7cdfaf0-9394-4053-b752-d609c837b729 | nova-conductor   | controller-0 | internal | enabled | up    | ...
| 692c2659-7188-42ec-9ad1-c88ac3020dc6 | nova-scheduler   | controller-0 | internal | enabled | up    | ...
| 5c7c9aad-696f-4dd1-a497-464bdd525e0c | nova-consoleauth | controller-0 | internal | enabled | up    | ...
+--------------------------------------+------------------+--------------+----------+---------+-------+ ...

Verify that controller-0 is unlocked, enabled, and available:

[wrsroot@controller-0 ~(keystone_admin)]$ system host-list
+----+--------------+-------------+----------------+-------------+--------------+
| id | hostname     | personality | administrative | operational | availability |
+----+--------------+-------------+----------------+-------------+--------------+
| 1  | controller-0 | controller  | unlocked       | enabled     | available    |
+----+--------------+-------------+----------------+-------------+--------------+

Controller-1 / Compute Hosts Installation

After initializing and configuring an active controller, you can add and configure a backup controller and additional compute hosts. For each host do the following:

Initializing Host

Power on Host. In host console you will see:

Waiting for this node to be configured.

Please configure the personality for this node from the
controller node in order to proceed.

Updating Host Host Name and Personality

On Controller-0, acquire Keystone administrative privileges:

controller-0:~$ source /etc/nova/openrc

Wait for Controller-0 to discover new host, list the host until new UNKNOWN host shows up in table:

[wrsroot@controller-0 ~(keystone_admin)]$ system host-list
+----+--------------+-------------+----------------+-------------+--------------+
| id | hostname     | personality | administrative | operational | availability |
+----+--------------+-------------+----------------+-------------+--------------+
| 1  | controller-0 | controller  | unlocked       | enabled     | available    |
| 2  | None         | None        | locked         | disabled    | offline      |
+----+--------------+-------------+----------------+-------------+--------------+

Use the system host-update to update host personality attribute:

[wrsroot@controller-0 ~(keystone_admin)]$ system host-update 2 personality=controller hostname=controller-1

Or for compute-0:

[wrsroot@controller-0 ~(keystone_admin)]$ system host-update 3 personality=compute hostname=compute-0

See also: 'system help host-update'

Unless it is known that the host's configuration can support the installation of more than one node, it is recommended that the installation and configuration of each node be serialized. For example, if the entire cluster has its virtual disks hosted on the host's root disk which happens to be a single rotational type hard disk, then the host cannot (reliably) support parallel node installation.

Monitoring Host

On Controller-0, you can monitor the installation progress by running the system host-show command for the host periodically. Progress is shown in the install_state field.

[wrsroot@controller-0 ~(keystone_admin)]$ system host-show <host> | grep install
| install_output      | text                                 |
| install_state       | booting                              |
| install_state_info  | None                                 |

Wait while the host is configured and rebooted. Up to 20 minutes may be required for a reboot, depending on hardware. When the reboot is complete, the host is reported as Locked, Disabled, and Online.

Listing Hosts

Once all Nodes have been installed, configured and rebooted, on Controller-0 list the hosts:

[wrsroot@controller-0 ~(keystone_admin)]$ system host-list
+----+--------------+-------------+----------------+-------------+--------------+
| id | hostname     | personality | administrative | operational | availability |
+----+--------------+-------------+----------------+-------------+--------------+
| 1  | controller-0 | controller  | unlocked       | enabled     | available    |
| 2  | controller-1 | controller  | locked         | disabled    | online       |
| 3  | compute-0    | compute     | locked         | disabled    | online       |
| 4  | compute-1    | compute     | locked         | disabled    | online       |
+----+--------------+-------------+----------------+-------------+--------------+

Controller-1 Provisioning

On Controller-0, list hosts

[wrsroot@controller-0 ~(keystone_admin)]$ system host-list
+----+--------------+-------------+----------------+-------------+--------------+
| id | hostname     | personality | administrative | operational | availability |
+----+--------------+-------------+----------------+-------------+--------------+
...
| 2  | controller-1 | controller  | locked         | disabled    | online       |
...
+----+--------------+-------------+----------------+-------------+--------------+

Provisioning Network Interfaces on Controller-1

In order to list out hardware port names, types, pci-addresses that have been discovered:

[wrsroot@controller-0 ~(keystone_admin)]$ system host-port-list controller-1

Check the interfaces list for controller-1 and select the interface intended for OAM network. Provision the Controller-1 OAM interface.

Unlocking Controller-1

Unlock Controller-1

[wrsroot@controller-0 ~(keystone_admin)]$ system host-unlock controller-1

Wait while the Controller-1 is rebooted. Up to 10 minutes may be required for a reboot, depending on hardware.

Controller-1 will remain in 'degraded' state until data-syncing is complete. The duration is dependant on the virtualization host's configuration - i.e., the number and configuration of physical disks used to host the nodes' virtual disks. Also, the management network is expected to have link capacity of 10000 (1000 is not supported due to excessive data-sync time).

Compute-N Host Provision

You must configure the network interfaces and the storage disks on a host before you can unlock it. For each Compute-N Host do the following:

Provisioning Network Interfaces on a Compute-N Host

On Controller-0, acquire Keystone administrative privileges:

controller-0:~$ source /etc/nova/openrc

Provision the data interface for Compute-N. Ensure that the interface used is one of those attached to host bridge with model type "virtio" (i.e., eth1000 and eth1001). The model type "e1000" emulated devices will not work for provider networks.

Otherwise use:

If the compute has more than 4 cpus, it is necessary to pin the vswitch as follows:

Unlocking a Compute-N Host

On Controller-0, use the system host-unlock command to unlock the Compute-N node:

[wrsroot@controller-0 ~(keystone_admin)]$ system host-unlock compute-0

Wait while the Compute-N is rebooted. Up to 10 minutes may be required for a reboot, depending on hardware. The host is rebooted, and its Availability State is reported as In-Test.

System Health Check

Listing StarlingX Nodes

On Controller-0, after a few minutes, all nodes shall be reported as Unlocked, Enabled, and Available:

[wrsroot@controller-0 ~(keystone_admin)]$ system host-list
+----+--------------+-------------+----------------+-------------+--------------+
| id | hostname     | personality | administrative | operational | availability |
+----+--------------+-------------+----------------+-------------+--------------+
| 1  | controller-0 | controller  | unlocked       | enabled     | available    |
| 2  | controller-1 | controller  | unlocked       | enabled     | available    |
| 3  | compute-0    | compute     | unlocked       | enabled     | available    |
| 4  | compute-1    | compute     | unlocked       | enabled     | available    |
+----+--------------+-------------+----------------+-------------+--------------+

Your StarlingX deployment is now up and running with 2x HA Controllers with Cinder Storage, 2x Computes and all OpenStack services up and running. You can now proceed with standard OpenStack APIs, CLIs and/or Horizon to load Glance Images, configure Nova Flavors, configure Neutron networks and launch Nova Virtual Machines.

System Alarm List

When all nodes are Unlocked, Enabled and Available: check 'fm alarm-list' for issues.
