Scope/Description

This article will cover how to update your PetaSAN nodes to the latest version. It may be necessary to perform this when standing up a second cluster with the intent of replicating data between the two.

Prerequisites

• An installed and configured PetaSAN based Ceph cluster
• PuTTy or similar SSH utility to SSH into the PetaSAN nodes
• Admin credentials for each node
• Internet access

Steps

• SSH into the terminal via PuTTy or another preferred SSH utility and log in with Admin credentials

• Ensure the nodes are pointing towards our dedicated 45Drives repository under “PetaSAN updates” by running the following command:

cat /etc/apt/sources.list

• Once this is verified, we run the command:

apt update

This command gives us a list of all the packages that can be updated and prepares everything to be updated.

• To make updating easier and require less interaction from the user, we’ll be applying the following

export DEBIAN_FRONTEND=noninteractive

Since it’s likely there will be many packages that need to be updated, we’ll be making this update process occur without user input.

• Now it’s time to apply the updates to everything. Run the following command and type “y” to continue.

apt -o Dpkg::Options::="--force-confdef" upgrade

• We will now install the PetaSAN update with the following command:

apt install petasan

Verification

Make sure everything is installed with the following command

dpkg -s petasan | grep Version
