About this Hands-on Lab

As of LXD 2.5, LXD offers the ability to manage the storage backends and pools used to store container data, allowing for greater stability, enhanced speeds, and convenient configuration. In this lab, we update a misconfigured storage pool, create an experimental storage block, and add a final storage block for backups.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Update the ZFS File System

View the current storage configuration for the server:
```
lxc storage list
```
Edit the default storage pool so it contains a description noting it’s for a test:
```
lxc storage edit default
```
Update the description parameter to "ZFS test pool".
Save and exit if editing the file directly.

Create a btrfs File System

Create a file system using the btrfs backend on /dev/nvme2n1, using 5GB of space:
```
lxc storage create experimental btrfs source=/dev/nvme2n1 size=5 
```
Edit the experimental storage pool so it contains a description noting it’s for a test:
```
lxc storage edit experimental
```

Update the description parameter to "btrfs test".
Save and exit if editing the file directly.

Create a Directory File System

Create a file system using the directory storage backend:

lxc storage create backups dir

Additional Resources

As part of your team's efforts to lift-and-shift a number of legacy applications on to LXC, you want to test btrfs, versus ZFS, as a potential backend for container storage. Additionally, you have been tasked with creating a backups script. Prepare your dev environment by updating the provided storage pool so it contains a description noting that it's for a test. After, create a 5G btrfs pool (called experimental) on /dev/nvme2n1 and ensure its description is updated. Additionally, create a backups storage space on localhost using directory storage.
