QuantaStor Local Update Mirror

Overview

QuantaStor systems are sometimes deployed in sites where there's no public internet access. On these deployments the QuantaStor systems are unable to directly access packages.osnexus.com and in order for the systems to run upgrades they will need a local package mirror.

The local package mirror is usually a VM, which has a copy of the QuantaStor repository, and other package files from packages.osnexus.com, so that the local DNS server can be configured to resolve packages.osnexus.com to the local mirror within the datacenter.

Our supported method is * Nginx + rsync of packages.osnexus.com:

• Nginx + rsync of packages.osnexus.com

Nginx + RSync Package Mirror Method

The Nginx + RSync method is the simplest and most common way to mirror the OSNexus package repository at packages.osnexus.com.

Follow the steps below to create a local mirror of the OSNEXUS QuantaStor update repository.

1. Contact support@osnexus.com to request assistance with the OSNEXUS QuantaStor replication mirror for rsync access. Support can also assist with the below process and any questions you may have.

2. Setup a Linux VM with a web server, below is an example config file using nginx on Ubuntu 18.04 or newer:

Edit the /etc/nginx/sites-enabled/osnexus-mirror file. Please note. The file may be different depending on your nginx version or Linux OS.

Replace yourserver.example.net with your web server DNS FQDN.

#
# A virtual host entry for an OSNEXUS QuantaStor mirror
#

server {
    listen       80;
    server_name  yourserver.example.net packages;
    location / {
        root /var/lib/www/packages-root;
        autoindex on;
    }
}

Now restart and ensure it is enabled to startup automatically.

systemctl enable nginx
systemctl restart nginx

3. ensure your ssh key is available for the root user as the id_rsa file under /root/.ssh/

4. Run an initial rsync to synchronize the QuantaStor update repo using the credentials and SSH key setup with the OSNEXUS support team in step 1.

mkdir -p /var/lib/www/packages-root/
RSYNC_PASSWORD=guest rsync -aPv rsync://guest@pkgmirror.osnexus.com/packages /var/lib/www/packages-root/

5. Add a cron entry that will run every day to synchronize your local mirror with the QuantaStor repo. Note that this requires ssh access from your mirror server to pkgmirror.osnexus.com

edit the /etc/cron.d/osnexus-mirror-sync file and add the below contents:
0 02 * * * root RSYNC_PASSWORD=guest /usr/bin/rsync -aPv rsync://guest@pkgmirror.osnexus.com/packages /var/lib/www/packages-root/

6. Add your new local mirror to your QuantaStor systems for all updates:

Replace yourserver.example.net with your web server DNS FQDN.

echo 'deb http://yourserver.example.net quantastor-bionic main' > /etc/apt/sources.list.d/osnexus.list
