Moving The etcd Database on T-1100 XL Appliances

All Gen 3.5 and Gen 4 Tufin Appliances come equipped with the etcd database. etcd is used for storing information which needs to be accessed simultaneously by multiple nodes, and needs to be capable of enabling TOS Aurora to meet high performance requirements. Therefore to enhance the performance of TOS Aurora, the etcd database needs to be stored in a separate disk on the data node server.

If you are running a High Availability deployment, this procedure needs to be repeated for each data node.

Gen 4 appliances come pre-configured with the etcd database already in a separate partition. Gen 3.5 T-1100 XL appliances require that you perform a manual procedure to move the etcd database to a separate partition. This requires that you split the RAID controller into two groups:

  • 4 discs which will run TufinOS and TOS Aurora

  • 2 discs which will run the etcd database

This procedure will erase all data on the appliance. Back up your data before beginning the procedure. After splitting the RAID controller, you are going to install 3.110 and TOS Aurora, and then restore the data.
This procedure is only relevant for Gen 3.5 T-1100XL Tufin appliances. T-1100 Tufin appliances have fewer discs, and therefore you cannot split the RAID controller. T-1100 appliances should only be used as worker nodes.

Prerequisites

Network Requirements

  • When logging into the appliances, you will need to log in as user root or another user with root permissions

General Requirements

  1. Check the appliance model by running the following command as user root.

    dmidecode -s chassis-version 2> /dev/null

    This procedure is only relevant for Gen 3.5 T-1100XL. Gen 4 appliances do not require this procedure, and you cannot split the RAID controller on other appliance models.

  2. Check the TufinOS version installed on the appliance by running the following command.

    cat /etc/redhat-release
  3. Backup your data.

Split the RAID Controller

  1. Log in to the appliance command line interface (via the physical console or via RMM), and reboot the appliance

  2. reboot

Install TufinOS and TOS

TOS Aurora was Previously Installed

  1. Install the latest version of TufinOS and the version of TOS that was previously installed on the appliance.

    See:

  2. Restore the data to the appliance. See Backup Restore Commands

TOS Classic was Previously Installed

  1. Install the latest version of TufinOS. See Installing TufinOS on an Appliance Using a USB Key

  2. Install the version of TOS classic that was previously installed on the appliance. See Installing TOS Classic

  3. Restore the data to the appliance. See Restoring TOS Classic from a Backup

  4. Upgrade to TOS Aurora. See Upgrade from TOS Classic to TOS Aurora
