Btrfs is an open-source, general-purpose file system for Linux. The name derives from the use of B-trees to store internal file system structures. Different names are used for the file system, including “Butter F S” and “B-tree F S.” Development of Btrfs began at Oracle in 200...
Create Btrfs Filesystem in Linux Files can be created in any characters except “/” andNULL. Btrfs has self-healing features and have the capability of spanning multiple volumes. In Btrfs we can shrink, grow the file-system, add or remove block device in online mode. It also provides sub...
Creating a file system writes information to the device and creates order of the empty space. This file system–related data consumes a small percentage of the space. The remaining space on the disk drive is split into small, consistently sized segments called blocks. Linux supports a number o...
TheBtrfs file systemhas certain caveats about swap files. At one time, there was a conflict between thecopy-on-writenature of Btrfs, which wanted to operate in one way and swap files that needed to operate in another. Some functions that swap files depend on were not implemented, and some...
Let’s say, you want to mount the Btrfs filesystem you’ve created earlier in the/datadirectory. So, create the/datadirectory as follows: $sudomkdir-v/data To mount the Btrfs filesystem created on the/dev/mapper/data storage devicein the/datadirectory, run the following command: ...
In Chapter 3, we discussed some of the top-level disk devices that the kernel makes available. In this chapter, we’ll discuss in detail how to work with disks on a Linux system. You’ll learn how to partition disks, create and maintain the filesystems that go inside disk partitions, ...
BTRFS, pronounced Butter FS, is a relatively new filesystem for Linux, based on Sun's ZFS, the one company behind most great UNIX-like inventions in the past 25 years, until devoured by Oracle. Never mind that. BTRFS is still considered unstable and thus not suitable for production environm...

In this chapter, we’ll discuss in detail how to work with disks on a Linux system. You’ll learn how to partition disks, create and maintain the filesystems that go inside disk partitions, and work with swap space. 在第三章中,我们讨论了内核提供的一些顶层磁盘设备。 在本章中,我们将...
Btrfs has become popular and powerful due to its advanced features like snapshot, rollback, and many more. In the upcoming days, this may lead to a default file system in the upcoming Linux distro. Hope you could gather some knowledge and mindset on how we can format the new disk to th...
