Overview of this book

Fedora Linux is a free and open-source platform designed for hardware, clouds, and containers that enables software developers and community members to create custom solutions for their customers. This book is a comprehensive guide focusing on workstation configuration for the modern system administrator. The book begins by introducing you to the philosophy underlying the open-source movement, along with the unique attributes of the Fedora Project that set it apart from other Linux distributions. The chapters outline best practices and strategies for essential system administration tasks, including operating system installation, first-boot configuration, storage, and network setup. As you make progress, you’ll get to grips with the selection and usage of top applications and tools in the tech environment. The concluding chapters help you get a clear understanding of the basics of version control systems, enhanced Linux security, automation, virtualization, and containers, which are integral to modern system administration. By the end of this book, you’ll have gained the knowledge needed to optimize day-to-day tasks related to Linux-based system administration.

Optimizing storage space size

In the previous section, we reviewed some of the features of the Btrfs filesystem. Now it is time to learn how to optimize this used storage space in more detail.

Btrfs reserves some raw storage at its lowest level because the volume needs to contain file data or volume metadata. For that, it allocates pieces of raw storage for use by the filesystem. A piece of storage gets referred to as a chunk. Its main function is to contain file data or volume metadata to replicate on the same volume or another similar device.

Storage space gets allocated to the chunks, and the space is used by the blocks. A chunk with no blocks used is unallocated; a chunk with one or more blocks used is allocated. All chunks can get allocated even if not all the space is used.

Btrfs uses delayed allocation to enable better disk allocation. Btrfs only allocates disk space when the system needs to get rid of dirty pages, so in the end, you get much larger allocations and...
