Rsync Commands for use with TrueNAS

Due to the way TrueNAS is built-duplicating files using Rsync requires some special flags to allow it to work

The below example command has been used and verified as working with TrueNAS Scale

How to Migrate a Unifi Controller from Cloudkey Gen 1 to Docker Container

Background: In an effort to streamline my local network and reduce the number of dedicated devices, I began an effort to move off of my Unifi Cloudkey Gen 1 to a Docker Container. While the migration should be straight forward-it is definitely not!

Before we begin, ensure that your existing Cloudkey is still connected to the network and operational. This is crucial to migrate the existing settings and to leverage the Unifi migration tooling for a site to save on having to wipe your configuration and rebuild everything from scratch.

Launch your container (it is up to you to follow the documentation for the specific maintainer's flavour to ensure you avoid data loss!) Once you can access the set up screen (on TCP:8443) for the containerized controller, you can proceed to Step 2
On your existing controller, Navigate to Settings -> Backup and download a settings only backup. This is CRITICAL because trying to import

Badblocks on TrueNAS Scale

Connect your USB drive to the machine
Navigate to the TrueNAS Scale shell by opening the menu, going to System Settings and then clicking on Shell
Locate the drive's device ID using the lsblk command
Check the recommended block size using the command blockdev --getbsz /dev/<YOUR BLOCK DEVICE ID>
Note the block size you got from the last command
STOP! Have you ensured that the USB device does NOT have any important data on it? If it does, stop now, unplug it from the TrueNAS Scale machine and back it up elsewhere! Running the specific badblocks command we'll use will destroy data on the drive!
Okay, you've confirmed there is no data on the drive you need? Good!
Fire up a new tmux session tmux new -s badblocks_

Resize an Ubuntu VM Disk on TrueNAS Scale

Shutdown the target VM
Locate the zvol where the storage is allocated in the Storage blade in the TrueNAS Scale Web UI
Resize the zvol by editing it-this can ONLY be increased, not shrunk!
Save your changes
Start your target VM up again
Log in to the VM
Execute the growpart command, ie. sudo growpart /dev/vda 2
Execute the resize2fs command, ie. sudo resize2fs /dev/vda2

Getting Your Python (Development) On!

Python for Windows is really easy to install-but what if you had started in the world of MacOS/*nix OSes and miss that single command to call Python or Pip? What if you don't have access to modify your environment PATH?

Windows PowerShell has a feature called "Profiles" which allows you to configure your PowerShell in a similar fashion as you could with Bash, Zsh, etc.

Pretty cool huh?
