Upgrade All-in-One Simplex¶

You can upgrade a StarlingX Simplex configuration with a new release of StarlingX software.

Prerequisites

Perform a full backup to allow recovery.

Note

Back up files in the /root directory prior to doing an upgrade, the /home size limit is 2000 MB. Although container image sizes are preserved, /root directory is not preserved during backup or restore operations, server replacement, or upgrades.

For more details on backup and what is included see Back Up System Data.

Note

The backup and restore function of an upgrade is specific to an AIO-SX deployment only.
Ensure that the following conditions are met:
- The system is patch current.
- There should be sufficient free space in /opt/platform-backup. Remove any unused files if necessary.
- The new software load has been imported.
- A valid license file has been installed.
Transfer the new release software load to controller-0 (or onto a USB stick); controller-0 must be active.

Note

Make sure that the /home/sysadmin directory has enough space (at least 2GB of free space), otherwise the upgrade may fail once it starts. If more space is needed, it is recommended to delete the .iso bootimage previously imported after the load-import command.
Transfer the new release software license file to controller-0 (or onto a USB stick).
Transfer the new release software signature to controller-0 (or onto a USB stick).

Note

The upgrade procedure includes steps to resolve system health issues.

End user container images in registry.local will be backed up during the upgrade process. This only includes images other than StarlingX system and application images. These images are limited to 5 GB in total size. If the system contains more than 5 GB of these images, the upgrade start will fail. For more details, see Detailed contents of a system backup.

Procedure

Source the platform environment.

$ source /etc/platform/openrc
~(keystone_admin)]$

Install the license file for the release you are upgrading to, for example, nn.nn.

~(keystone_admin)]$ system license-install <license_file>

For example,

~(keystone_admin)]$ system license-install license.lic

Import the new release.

Run the load-import command on controller-0 to import the new release.

First, source /etc/platform/openrc.

You must specify an exact path to the *.iso bootimage file and to the *.sig bootimage signature file.

$ source /etc/platform/openrc
~(keystone_admin)]$ system load-import /home/sysadmin/<bootimage>.iso \
<bootimage>.sig
+--------------------+-----------+
| Property           | Value     |
+--------------------+-----------+
| id                 | 2         |
| state              | importing |
| software_version   | nn.nn     |
| compatible_version | nn.nn     |
| required_patches   |           |
+--------------------+-----------+

The load-import must be done on controller-0 and accepts relative paths.

Note

This will take a few minutes to complete.

Check to ensure the load was successfully imported.

~(keystone_admin)]$ system load-list
+----+----------+------------------+
| id | state    | software_version |
+----+----------+------------------+
| 1  | active   | nn.nn            |
| 2  | imported | nn.nn            |
+----+----------+------------------+

Apply any required software updates.

The system must be ‘patch current’. All software updates related to your current StarlingX software release must be, uploaded, applied, and installed.

All software updates to the new StarlingX release, only need to be uploaded and applied. The install of these software updates will occur automatically during the software upgrade procedure as the hosts are reset to load the new release of software.

To find and download applicable updates, visit the a StarlingX mirror.

For more information, see Manage Software Updates.
Confirm that the system is healthy.

Note

Do not modify protected filesystem directories before backup.

Check the current system health status, resolve any alarms and other issues reported by the system health-query-upgrade command, then recheck the system health status to confirm that all System Health fields are set to OK.
```
~(keystone_admin)]$ system health-query-upgrade
System Health:
All hosts are provisioned: [OK]
All hosts are unlocked/enabled: [OK]
All hosts have current configurations: [OK]
All hosts are patch current: [OK]
Ceph Storage Healthy: [OK]
No alarms: [OK]
All kubernetes nodes are ready: [OK]
All kubernetes control plane pods are ready: [OK]
Required patches are applied: [OK]
License valid for upgrade: [OK]
No instances running on controller-1: [OK]
All kubernetes applications are in a valid state: [OK]
Active controller is controller-0: [OK]
```
By default, the upgrade process cannot be run and is not recommended to be run with Active Alarms present. However, management affecting alarms can be ignored with the --force option with the system upgrade-start command to force the upgrade process to start.

Note

It is strongly recommended that you clear your system of any and all alarms before doing an upgrade. While the --force option is available to run the upgrade, it is a best practice to clear any alarms.
Start the upgrade.
```
~(keystone_admin)]$ system upgrade-start
+--------------+--------------------------------------+
| Property     | Value                                |
+--------------+--------------------------------------+
| uuid         | 61e5fcd7-a38d-40b0-ab83-8be55b87fee2 |
| state        | starting                             |
| from_release | nn.nn                                |
| to_release   | nn.nn                                |
+--------------+--------------------------------------+
```
This will back up the system data and images to /opt/platform-backup. /opt/platform-backup is preserved when the host is reinstalled. With the platform backup, the size of /home/sysadmin must be less than 2GB.

This process may take several minutes.

When the upgrade state is upgraded to started the process is complete.

Any changes made to the system after this point will be lost when the data is restored.

The following upgrade state applies once this command is executed:
- started:
  - State entered after system upgrade-start completes.
  - Release nn.nn system data (for example, postgres databases) has been exported to be used in the upgrade.
  - Configuration changes must not be made after this point, until the upgrade is completed.
As part of the upgrade, the upgrade process checks the health of the system and validates that the system is ready for an upgrade.

The upgrade process checks that no alarms are active before starting an upgrade.

Note

Use the command system upgrade-start --force to force the upgrades process to start and to ignore management affecting alarms. This should ONLY be done if you feel these alarms will not be an issue over the upgrades process.

Check the upgrade state.

~(keystone_admin)]$ system upgrade-show
+--------------+--------------------------------------+
| Property     | Value                                |
+--------------+--------------------------------------+
| uuid         | 61e5fcd7-a38d-40b0-ab83-8be55b87fee2 |
| state        | started                              |
| from_release | nn.nn                                |
| to_release   | nn.nn                                |
+--------------+--------------------------------------+

Ensure the upgrade state is started. It will take several minutes to transition to the started state.

(Optional) Copy the upgrade data from the system to an alternate safe location (such as a USB drive or remote server).

The upgrade data is located under /opt/platform-backup. Example file names are:

lost+found upgrade_data_2020-06-23T033950_61e5fcd7-a38d-40b0-ab83-8be55b87fee2.tgz
```
~(keystone_admin)]$ ls /opt/platform-backup/
```

Lock controller-0.

~(keystone_admin)]$ system host-lock controller-0

Upgrade controller-0.

This is the point of no return. All data except /opt/platform-backup/ will be erased from the system. This will wipe the rootfs and reboot the host. The new release must then be manually installed (via network or USB).

~(keystone_admin)]$ system host-upgrade controller-0
WARNING: THIS OPERATION WILL COMPLETELY ERASE ALL DATA FROM THE SYSTEM.
Only proceed once the system data has been copied to another system.
Are you absolutely sure you want to continue?  [yes/N]: yes

Install the new release of StarlingX Simplex software via network or USB.
Verify and configure IP connectivity. External connectivity is required to run the Ansible upgrade playbook. The StarlingX boot image will DHCP out all interfaces so the server may have obtained an IP address and have external IP connectivity if a DHCP server is present in your environment. Verify this using the ip addr command. Otherwise, manually configure an IP address and default IP route.
Restore the upgrade data.
```
~(keystone_admin)]$ ansible-playbook /usr/share/ansible/stx-ansible/playbooks/upgrade_platform.yml
```
Once the host has installed the new load, this will restore the upgrade data and migrate it to the new load.

The playbook can be run locally or remotely and must be provided with the following parameter:

ansible_become_pass

The ansible playbook will check /home/sysadmin/<hostname>.yml for these user configuration override files for hosts. For example, if running ansible locally, /home/sysadmin/localhost.yml.

By default the playbook will search for the upgrade data file under /opt/platform-backup. If required, use the upgrade_data_file parameter to specify the path to the upgrade_data.

Note

This playbook does not support replay.

Note

This can take more than one hour to complete.

Once the data restoration is complete the upgrade state will be set to upgrading-hosts.

Check the status of the upgrade.

~(keystone_admin)]$ system upgrade-show
+--------------+--------------------------------------+
| Property     | Value                                |
+--------------+--------------------------------------+
| uuid         | 61e5fcd7-a38d-40b0-ab83-8be55b87fee2 |
| state        | upgrading-hosts                      |
| from_release | nn.nn                                |
| to_release   | nn.nn                                |
+--------------+--------------------------------------+

Unlock controller-0.
```
~(keystone_admin)]$ system host-unlock controller-0
```
This step is required only for Simplex systems that are not a subcloud.
Activate the upgrade.

During the running of the upgrade-activate command, new configurations are applied to the controller. 250.001 (hostname Configuration is out-of-date) alarms are raised and are cleared as the configuration is applied. The upgrade state goes from activating to activation-complete once this is done.
```
~(keystone_admin)]$ system upgrade-activate
+--------------+--------------------------------------+
| Property     | Value                                |
+--------------+--------------------------------------+
| uuid         | 61e5fcd7-a38d-40b0-ab83-8be55b87fee2 |
| state        | activating                           |
| from_release | nn.nn                                |
| to_release   | nn.nn                                |
+--------------+--------------------------------------+
```
The following states apply when this command is executed.

activation-requested
State entered when system upgrade-activate is executed.

activating
State entered when we have started activating the upgrade by applying new configurations to the controller and compute hosts.

activating-hosts
State entered when applying host-specific configurations. This state is entered only if needed.

activation-complete
State entered when new configurations have been applied to all controller and compute hosts.
1. Check the status of the upgrade again to see it has reached activation-complete.
```
~(keystone_admin)]$ system upgrade-show
+--------------+--------------------------------------+
| Property     | Value                                |
+--------------+--------------------------------------+
| uuid         | 61e5fcd7-a38d-40b0-ab83-8be55b87fee2 |
| state        | activation-complete                  |
| from_release | nn.nn                                |
| to_release   | nn.nn                                |
+--------------+--------------------------------------+
```
Note

This can take more than half an hour to complete.

activation-failed
Check /var/log/sysinv.log for further information.

Complete the upgrade.

~(keystone_admin)]$ system upgrade-complete
+--------------+--------------------------------------+
| Property     | Value                                |
+--------------+--------------------------------------+
| uuid         | 61e5fcd7-a38d-40b0-ab83-8be55b87fee2 |
| state        | completing                           |
| from_release | nn.nn                                |
| to_release   | nn.nn                                |
+--------------+--------------------------------------+

Delete the imported load.

~(keystone_admin)]$ system load-list
+----+----------+------------------+
| id | state    | software_version |
+----+----------+------------------+
| 1  | imported | nn.nn            |
| 2  | active   | nn.nn            |
