Update/Rebuild NTA1000 System Drive

This article provides instructions for rebuilding the system drive of your NTA1000 to the factory default state. This might need to be done to bring your system drive up to the latest operating system. It might also need to be done in case of any corruption of the filesystem.

NOTE: The instructions below are for NTA1000v7, NTA1000v6, NTA1000v5 hardware platforms only. If you have an older NTA1000(v1,v2,v3,v4), please contact the QA Cafe Support team If you have an NTA3000, please refer to this document.

Disk Image Release Notes


Your NTA1000 has two internal drives: a system drive and a data drive. The system drive contains the Linux operating system, CDRouter software, and the qacafe user account directory. The data drive contains all of your CDRouter data (configs, packages, results, etc.).

If you have any files on the system drive that you want to restore later, please back them up before performing this operation. Rebuilding a drive will PERMANENTLY DELETE all existing files on the drive. Since only the system drive will be rebuilt, CDRouter data located on the data drive will not be affected by this. However, it’s still a good idea and good practice to perform a backup of your data drive as well.

NOTE: This procedure requires an active Internet connection on the NTA1000. All steps in the procedure below will be executed directly from your NTA1000 system. If the NTA1000 does not have Internet access, consider temporarily connecting it to the internet just for this procedure. If this is not possible, please contact the QA Cafe Support team

Step 1: Install the nta1000-create-image package

The QA Cafe nta1000-create-image package may be installed automatically from the QA Cafe rpm repository using the yum command. The exact command to use will be determined by the operating system you’re currently running. Look at the output from the following command.

cat /etc/redhat-release

You should see something like one of the following:

Rocky Linux release 8.8 (Green Obsidian)
Rocky Linux release 8.6 (Green Obsidian)
Rocky Linux release 8.4 (Green Obsidian)
CentOS Linux release 8.1.1911 (Core)
CentOS Linux release 7.7.1908 (Core)
  • For Rocky Linux release 8.x: A version of the nta1000-create-image package should already be installed, but be sure to get the latest version:

    yum install nta1000-create-image
  • For CentOS Linux release 8.x:

    yum install --disablerepo="*" --enablerepo=nta1000-base nta1000-create-image
  • For CentOS Linux release 7.x (or earlier):

    yum update --disablerepo=nta1000-base --disablerepo=nta1000-updates --disablerepo=nta1000-kernel ca-certificates
    yum install --enablerepo=nta1000-base nta1000-create-image

This will install a python script in the /usr/share/nta1000/bin directory. This script will be used in the next step.

Step 2: Create the bootable USB drive

The script creates a bootable USB drive that is used to clone a new system image onto the system drive of the NTA1000.

  • To get started, plug a USB drive into the NTA1000. Note that the USB drive will be overwritten, so any data currently on the drive will be destroyed.

  • Next, run the script as the root user using the following command:


    The script will verify that a properly sized USB drive (>= 4GB) exists and will abort if one is not found.

  • If a properly sized USB drive is found, the script will download and copy the appropriate QA Cafe Disk Image Utility package from the QA Cafe repository server and then burn it to the USB drive.

  • Once the image utility has been burned to the USB drive, the script will provide additional instructions for properly booting the system from the USB drive.

    • Press p to power off the system and continue with Step 3 below.
    • Press c to exit the utility if you wish to continue the procedure later instead.

The following screenshot shows an example of what you should see when running the steps above.

Step 3: Boot the NTA1000 from the USB drive

  • Power on the NTA1000 with the bootable USB drive created in the previous step inserted.

  • Press the F7 key to get to the boot menu when the initial splash screen is displayed on the monitor.

  • Select the USB drive and press enter. DO NOT select any USB entry with UEFI Note that the screenshot below is only an example of what may be displayed; the exact output may be different in some cases.

Step 4: Install System Image from USB drive

  • After the NTA1000 boots from the USB drive, the QA Cafe NTA1000 Disk Image Utility will start and display the menu below.

  • Select (s) Rebuild system drive - This will begin the imaging process.

  • After the imaging process completes, the menu will be displayed again.

  • Remove the USB drive, then select (r) Reboot to reboot your system.

Step 5: Install CDRouter software and license

Once the NTA1000 has rebooted, it should be running Rocky Linux 8. This may be verified by running the following command in a terminal window:

cat /etc/redhat-release

Output should be:

Rocky Linux release 8.8 (Green Obsidian)

Now that the system drive has been successfully rebuilt, CDRouter must be reinstalled.

Please follow the instructions in the “Manual installation using the command line” section of the CDRouter Installation Guide.

Once CDRouter has been reinstalled, an active CDRouter license file must also be installed. This can be done automatically by running the following command:

cdrouter-cli -update-license

The following command may be used to verify that CDRouter and a valid, active license file have been properly installed:

cdrouter-cli -info

CDRouter’s web UI, and all CDRouter data should now be available.
