Basic Introduction Btrfs (also known as B-tree, Butter FS, Better FS), GPL authorization, Oracle R D from 2007, realistic replication and update mechanism CoW, mainly to replace ext2, ext3, ext4, its main functions include: For example, if we want to modify file A, and the COW mechanism is to copy file A to file B first, we will modify the copy file B, it is equiva

1. Preliminary understandingThe Btrfs system is a file system type developed by Oracle to replace the EXT series file system. With the rapid development of the network, the file system of EXT system does not meet the need in many aspects. Core features: Multi-Physical volume support: Btrfs can be composed of multiple underlying physical volumes, RAID support for online "add", "Remove", "modify", copy-on-wri

Btrfs, also known as Butter FS, Better FS, or B-tree FS, is a modern file system that Oracle began designing and developing in 2007, and it was merged into the Linux 2.6.29 kernel in 2009. Btrfs is licensed under the GPL and is not very stable, although many Linux distributions are integrated, but are not used as default file systems. Btrfs is widely integrated b

btrfs File System:Btrfs (b-tree file system, usually read as Butter Fs,better FS or Btree FS), is licensed by the GPL and is supported by Oracle in 2007 and is in support of the write-on-copy (COW) filesystem. The goal is to replace the Linux current Ext3 file system, improve the ext3 limit, especially the size of individual files, total file system size or file check and join EXT3 unsupported features such as writable snapshots (writable snapshots),

What is Btrfs?Btrfs, a cow (copy-on-write) file system announced and in progress by Oracle in 2007. The goal is to replace Linux's current Ext3 file system to improve ext3 limitations, especially single file size limits, total file system size limits, and the addition of file checksum features. Added some features not currently supported by EXT3/4, such as writable disk snapshots (snapshots), and support fo

Btrfs (b-tree file System,b-tree) is a new cow (copy-on-write, copy-on-write) file system for Linux development. It was originally developed by Oracle in 2007 and formally released its stable version in August 2014. The goal of developing btrfs is to address the problem of missing pools, snapshots, checksums, and integrated cross-device access in Linux file systems, with the aim of achieving large-scale sto

about Btrfs The file system appears to be a relatively stable part of the kernel, and over the years, people have been using the Ext2/3,ext file system for its excellent stability as the de facto Linux standard file system. In recent years, EXT2/3 has exposed some extensibility problems, so it has spawned ext4. The dev version of EXT4 was integrated in the Linux2.6.19 kernel released in 2008. When the 2.6.28 kernel was released, EXT4 ended the develo

Joseph fbacik of Fedora announced on the developer's email list that the default use of the btrfs File System feature was postponed to Fedora17. The reason for the delay is very simple because BTRFS's error checking tool btrfsck was not available before the ora16 feature was frozen, and the performance problem has been plagued by BTRFS. At the same time, some BTRFS
