|
||
==========================================================================
|
||
Restore a Subcloud/Group of Subclouds from Backup Data Using DCManager CLI
|
||
==========================================================================
|
||
|
||
A subcloud can be restored from its backup data previously stored centrally on
|
||
the system controller or locally on the subcloud using dcmanager command line
|
||
interface (|CLI|). The subcloud install data must be available for this
|
||
operation to proceed. The subcloud must support Redfish Virtual Media Service
|
||
(version 1.2 or higher) if remote installation is required.
|
||
|
||
.. rubric:: |context|
|
||
|
||
The |CLI| command :command:`dcmanager subcloud-backup restore` can be used to
|
||
restore a subcloud or a group of subclouds. By default, the restore is done
|
||
from subcloud backup data on the central systemController. The command accepts
|
||
the following parameters/options:
|
||
|
||
``--with-install``
|
||
Perform remote installation of the subcloud prior to execution of restore
|
||
procedure. The subcloud must support Redfish Virtual Media Service (version
|
||
1.2 or higher) to use this option.
|
||
|
||
``--local-only``
|
||
Use the local backup archive (default local storage
|
||
``/opt/platform-backup/backups/<release-version>``). If not specified, the
|
||
subcloud backup archive on the central systemController will be used.
|
||
|
||
``--registry-images``
|
||
Restore saved container images to registry.local as part of restore
|
||
procedure (local storage only)
|
||
|
||
``--subcloud <subcloud-name>``
|
||
The subcloud to restore.
|
||
|
||
``--group <subcloud-group-name>``
|
||
The group of subclouds to restore.
|
||
|
||
``--restore-values <yaml-file>``
|
||
The yaml file containing the customization parameters.
|
||
|
||
- ``wipe_ceph_osds=false``: To keep the Ceph cluster data intact.
|
||
- ``wipe_ceph_osds=true``: To wipe the Ceph cluster entirely.
|
||
- ``on_box_data=true``: To indicate that the backup data file is under
|
||
/opt/platform-backup directory on the local machine.
|
||
- ``bootstrap_address``: List of subclouds and their corresponding
|
||
bootstrap addresses for connectivity.
|
||
|
||
- ``add_docker_prefix``: For more details, see
|
||
:ref:`installing-a-subcloud-using-redfish-platform-management-service`.
|
||
|
||
.. code-block:: none
|
||
|
||
bootstrap_address:
|
||
<subcloud_name1>: <subcloud_bootstrap_address1>
|
||
<subcloud_name2>: <subcloud_bootstrap_address2>
|
||
|
||
.. note::
|
||
|
||
The ``bootstrap_address`` key is only necessary for the restore of
|
||
manually installed subclouds. For the subclouds installed via
|
||
Redfish, the ``bootstrap_address`` is already available in the
|
||
install values.
|
||
|
||
See :ref:`Run Restore Playbook Locally on the Controller
|
||
<running-restore-playbook-locally-on-the-controller>` for the list of
|
||
configurable system restore parameters.
|
||
|
||
``--sysadmin-password <sysadmin-password>``
|
||
If not specified, user will be prompted for the password. Recommend that
|
||
this option is ONLY used for automation; i.e., for interactive use, don't
|
||
use option and specify password on prompting, so as to avoid sysadmin
|
||
password getting into log files.
|
||
|
||
The ``--subcloud/--group`` is a mandatory parameter.
|
||
|
||
"When ``--registry-images`` option is applied, the entire registry filesystem
|
||
which contains both platform and user container images will be restored.
|
||
|
||
After the subcloud has been re-installed with the desired release version, the
|
||
backup archive for that release will be transferred to the subcloud for the
|
||
restore operation by default. If ``--local-only`` option is specified, the local
|
||
backup archive for the release will be used instead.
|
||
|
||
It is possible to specify a custom location of the backup file that resides on
|
||
the subcloud using ``--restore-values`` option and by setting
|
||
``initial_backup_dir`` and ``backup_filename`` in the provided
|
||
``restore_values`` yaml file. Please ensure this custom backup file is not
|
||
corrupted and is compatible with software release the subcloud was installed
|
||
with.
|
||
|
||
|
||
To restore images from a custom backup file on the subcloud using
|
||
``--restore-values <yaml-file>`` option, the registry_backup_filename parameter
|
||
must be set in ``restore_values`` yaml file.

Restore a single subcloud
|
||
-------------------------
|
||
|
||
.. rubric:: |prereq|
|
||
|
||
- The System Controller is healthy and ready to accept dcmanager related
|
||
commands.
|
||
|
||
- The subcloud is unmanaged and is in a valid state for restore operation
|
||
(i.e. not being restored, installed, bootstrapped, deployed or rehomed).
|
||
|
||
- The subcloud install data is available.
|
||
|
||
- The backup file(s) exists and is compatible with the software release the
|
||
subcloud is being restored to.
|
||
|
||
|
||
.. rubric:: |proc|
|
||
|
||

|
||
in central storage:
|
||
|
||

~(keystone_admin)]$ dcmanager subcloud-backup restore --subcloud <subcloud-name> --with-install --sysadmin-password <sysadmin-password>
|
||
|
||

|
||
|
||
.. code-block:: none
|
||
|
||
~(keystone_admin)]$ dcmanager subcloud-backup restore --subcloud <subcloud-name> --sysadmin-password <sysadmin-password>
|
||
|
||
To restore a subcloud, including remote installation, from system backup data
|
||

|
||
|
||
.. code-block:: none
|
||
|
||
~(keystone_admin)]$ dcmanager subcloud-backup restore --subcloud <subcloud-name> --with-install --local-only --sysadmin-password <sysadmin-password>
|
||
|
||
To restore a subcloud, including remote installation, from system backup and
|
||

|
||
|
||
.. code-block:: none
|
||
|
||
~(keystone_admin)]$ dcmanager subcloud-backup restore --subcloud <subcloud-name> --local-only --registry-images --sysadmin-password <sysadmin-password>
|
||
|
||

|
||
|
||
The ``--registry-images`` option can only be used with ``--local-only``
|
||
option.
|
||
|
||
|
||
To restore a pre-installed subcloud from system and images backup data stored
|
||

|
||
|
||

|
||

||
.. code-block:: none
|
||
|
||
initial_backup_dir: /home/sysadmin/mybackup_dir
|
||
backup_filename: test_platform_backup.tgz

||
|
||
#. Then, run the command:
|
||
|
||

|
||
|
||

If the restore operation completes successfully, the subcloud will become
|
||
online and the ``deploy_status`` will be set to 'complete'.
|
||
|
||
Please continue with :ref:`Post restore procedure <post-restore-procedure>`.
|
||
|
||
If the restore operation fails, :command:`dcmanager subcloud errors` command
|
||
can be used to view the error.
|

|
||
|
||
Restore a group of subclouds
|
||
----------------------------
|
||
|
||
The above subcloud-backup restore operations can be performed for a group of
|
||
subclouds simultaneously by replacing ``--subcloud`` option with ``--group``
|
||
option. For instance, to restore a group of subclouds with remote installation
|
||
from their system data in central storage:
|
||
|
||
.. code-block:: none
|
||
|
||
~(keystone_admin)]$ dcmanager subcloud-backup restore --group <group> --with-install --sysadmin-password <sysadmin-password>
|
||
|
||
|
||
If all subclouds in the group are not in the valid state for restore, an error
|
||
message will be displayed. If some of the subclouds in the group meet restore
|
||
operation criteria, a list will be displayed.
|
||
|
||
Sample group restore response:
|
||
|
||
.. code-block:: none

procedure available in :ref:`restoring-starlingx-system-data-and-storage` for
