Upgrade NetQ Appliances and Virtual Machines

The first step in upgrading your NetQ installation to NetQ 4.3 is upgrading your NetQ appliances or VMs.

Before You Upgrade

Back up NetQ Data

This is an optional step for on-premises deployments. Refer to Back Up and Restore NetQ. NetQ Cloud Appliances and VMs create backups automatically.

Download Software and Update Debian Packages

  1. Download the relevant software.

    1. On the NVIDIA Application Hub, log in to your account.
    2. Select NVIDIA Licensing Portal.
    3. Select Software Downloads from the menu.
    4. Click Product Family and select NetQ.
    5. Select the relevant software for your hypervisor:

      If you are upgrading NetQ Platform software for a NetQ On-premises Appliance or VM, select NetQ SW 4.3 Appliance to download the NetQ-4.3.0.tgz file. If you are upgrading NetQ software for a NetQ Cloud Appliance or VM, select NetQ SW 4.3 Appliance Cloud to download the NetQ-4.3.0-opta.tgz file.

    6. If prompted, agree to the license agreement and proceed with the download.

    For enterprise customers, if you do not see a link to the NVIDIA Licensing Portal on the NVIDIA Application Hub, contact NVIDIA support.

    For NVIDIA employees, download NetQ directly from the NVIDIA Licensing Portal.

  2. Copy the file to the /mnt/installables/ directory on your appliance or VM.

  3. Update /etc/apt/sources.list.d/cumulus-netq.list to netq-4.3 as follows:

    cat /etc/apt/sources.list.d/cumulus-netq.list
    deb [arch=amd64] https://apps3.cumulusnetworks.com/repos/deb bionic netq-4.3
  4. Update the NetQ debian packages.

Run the Upgrade

Perform the following steps using the cumulus user account.

Pre-installation Checks

Verify the following items before upgrading NetQ. For cluster deployments, verify steps 1 and 3 on all nodes in the cluster:

  1. Check if enough disk space is available before you proceed with the upgrade:
cumulus@netq-appliance:~$ df -h /
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1       248G   70G  179G  28% /

The recommended Use% to proceed with installation is under 70%. You can delete previous software tarballs in the /mnt/installables/ directory to regain some space. If you can not bring disk space to under 70% usage, contact the NVIDIA support team.

  1. Run the netq show opta-health command and check that all pods are in the READY state. If not, contact the NVIDIA support team.

  2. Check if the certificates have expired:

cumulus@netq-appliance:~$ sudo grep client-certificate-data /etc/kubernetes/kubelet.conf | cut -d: -f2 | xargs | base64 -d | openssl x509 -dates -noout | grep notAfter | cut -f2 -d=
Dec 18 17:53:16 2021 GMT

If the date in the above output is in the past, run the following commands before proceeding with the upgrade:

sudo cp /etc/kubernetes/kubelet.conf /etc/kubernetes/kubelet.conf.bak
sudo sed -i 's/client-certificate-data.*/client-certificate: \/var\/lib\/kubelet\/pki\/kubelet-client-current.pem/g' /etc/kubernetes/kubelet.conf
sudo sed -i 's/client-key.*/client-key: \/var\/lib\/kubelet\/pki\/kubelet-client-current.pem/g' /etc/kubernetes/kubelet.conf
sudo systemctl restart kubelet

Check if the kubelet process is running with the sudo systemctl status kubelet command before proceeding with the upgrade.

If any issue occurs, contact the NVIDIA Support team.

Upgrade Using the NetQ CLI

After completing the preparation steps, upgrade your NetQ On-premises, Cloud Appliances, or VMs using the NetQ CLI.

To upgrade your NetQ software:

  1. Run the appropriate netq upgrade command.
netq upgrade bundle /mnt/installables/NetQ-4.3.0.tgz
netq upgrade bundle /mnt/installables/NetQ-4.3.0-opta.tgz
  1. After the upgrade completes, confirm the upgrade was successful.

    cumulus@<hostname>:~$ cat /etc/app-release
