Rollback LTS2 5.6

With LTS2, it is necessary to migrate existing management server environments running on VMs to be able to run as a management cluster. The following steps walk through that process.

Download and Install new Airctl packages.

Bash

./download.sh v-5.6.0-xxxx
./install.sh v-5.6.0-xxxx

Run Pre-Checks

Bash

/opt/pf9/airctl/airctl migrate-pre-checks --config /opt/pf9/airctl/conf/airctl-config.yaml

Backup Management Server

Bash

/opt/pf9/airctl/airctl backup --config /opt/pf9/airctl/conf/airctl-config.yaml

Ensure that the backup generated has the mongo and mysql data.

Stop and delete Management Server

Bash

/opt/pf9/airctl/airctl stop --config /opt/pf9/airctl/conf/airctl-config.yaml

Bash

/opt/pf9/airctl/airctl unconfigure-du --config /opt/pf9/airctl/conf/airctl-config.yaml

Update Airctl config to use new Management Server values

Specifically, the following fields need to be set in**````/opt/pf9/airctl/conf/airctl-config.yaml:``**

{% tabs %} {% tab language="yaml" title="YAML" %} {% code %}

installDriver: DDU

kubeCfgPath: /etc/nodelet/airctl-mgmt/certs/admin.kubeconfig
bootstrapCfgPath: /etc/nodelet/airctl-mgmt/airctl-mgmt.yaml
svcDeploymentTimeout: 600
storageProvider: hostpath-provisioner
externalIP: <external-ip>
privateRegistryType: DU

{% endcode %} {% endtab %} {% endtabs %}

The externalIP needs to be a VIP on the same L2 network as the nodelet host(s), but different from the nodelet host's IP.

Nodelet Prerequisites

Uninstall docker

{% tabs %} {% tab language="bash" title="Bash" %} {% code %}

yum remove docker-ce containerd

{% endcode %} {% endtab %} {% endtabs %}

Install libcgroup-tools

{% tabs %} {% tab language="bash" title="Bash" %} {% code %}

yum install libcgroup-tools

{% endcode %} {% endtab %} {% endtabs %}

Deploy nodelet cluster

{% tabs %} {% tab language="bash" title="Bash" %} {% code %}

/opt/pf9/airctl/airctl advanced-ddu create-mgmt --config /opt/pf9/airctl/conf/airctl-config.yaml

{% endcode %} {% endtab %} {% endtabs %}

Initialize airctl

{% tabs %} {% tab language="bash" title="Bash" %} {% code %}

/opt/pf9/airctl/airctl init --config /opt/pf9/airctl/conf/airctl-config.yaml

{% endcode %} {% endtab %} {% endtabs %}

Deploy Management Cluster

{% tabs %} {% tab language="bash" title="Bash" %} {% code %}

/opt/pf9/airctl/airctl start --config /opt/pf9/airctl/conf/airctl-config.yaml

{% endcode %} {% endtab %} {% endtabs %}

Wait for Management Cluster services to be up

The airctl status command reports the state of the Management Server. Wait until the status command reports the task state as ready.

{% tabs %} {% tab language="bash" title="Bash" %} {% code %}

[centos@airctl-host ~]$ /opt/pf9/airctl/airctl --config /opt/pf9/airctl/conf/airctl-config.yaml status
------------- deployment details ---------------
fqdn:                airctl-1.pf9.localnet
cluster:             airctl-1.pf9.localnet
task state:          ready
-------- region service status ----------
task state:        ready
desired services:  42
ready services:    42

{% endcode %} {% endtab %} {% endtabs %}

Migrate Management Server data to Management Cluster

{% tabs %} {% tab language="bash" title="Bash" %} {% code %}

/opt/pf9/airctl/airctl migrate --backup-file <tar.gz-of-cdu-backup> --config /opt/pf9/airctl/conf/airctl-config.yaml

{% endcode %} {% endtab %} {% endtabs %}

Same version upgrade of Management Server

{% tabs %} {% tab language="bash" title="Bash" %} {% code %}

/opt/pf9/airctl/airctl upgrade --config /opt/pf9/airctl/conf/airctl-config.yaml

{% endcode %} {% endtab %} {% endtabs %}

The airctl status command reports the state of the Management Server. Wait until the status command reports the task state as ready.

{% tabs %} {% tab language="bash" title="Bash" %} {% code %}

[centos@airctl-host ~]$ /opt/pf9/airctl/airctl --config /opt/pf9/airctl/conf/airctl-config.yaml status
------------- deployment details ---------------
fqdn:                airctl-1.pf9.localnet
cluster:             airctl-1.pf9.localnet
task state:          ready
-------- region service status ----------
task state:        ready
desired services:  42
ready services:    42

{% endcode %} {% endtab %} {% endtabs %}

Configure PMK hosts to work with Management Cluster

{% tabs %} {% tab language="bash" title="Bash" %} {% code %}

/opt/pf9/airctl/airctl configure-hosts --reset-pf9-managed-docker-conf --skip-docker-img-import --config /opt/pf9/airctl/conf/airctl-config.yaml

{% endcode %} {% endtab %} {% endtabs %}

Upgrade PMK hosts to new components of Management Cluster

{% tabs %} {% tab language="bash" title="Bash" %} {% code %}

/opt/pf9/airctl/airctl upgrade-hosts --config /opt/pf9/airctl/conf/airctl-config.yaml

{% endcode %} {% endtab %} {% endtabs %}

Wait for Task State to report Ready again

{% tabs %} {% tab language="bash" title="Bash" %} {% code %}

[centos@airctl-host ~]$ /opt/pf9/airctl/airctl --config /opt/pf9/airctl/conf/airctl-config.yaml status
------------- deployment details ---------------
fqdn:                airctl-1.pf9.localnet

task state:          ready
-------- region service status ----------
task state:        ready

ready services:    42

{% endcode %} {% endtab %} {% endtabs %}
