What is btrfs
Basic description of btrfs. Strengths, weaknesses, why is this important, etc.
Features:
- Extent based file storage (2^64 max file size)
- Space efficient packing of small files
- Space efficient indexed directories
- Dynamic inode allocation
- Writable snapshots
- Subvolumes (separate internal filesystem roots)
- Object level mirroring and striping
- Checksums on data and metadata (multiple algorithms available)
- Compression
- Integrated multiple device support, with several raid algorithms
- Online filesystem check
- Very fast offline filesystem check
- Efficient incremental backup and FS mirroring
- Online filesystem defragmentation
How to install
Ubuntu 8.10 Intrepid

Kernel Module Dependencies
8.10 Kernel 2.6.27-9-generic
- CONFIG_LIBCRC32C=m
- CONFIG_ZLIB_INFLATE=y
- CONFIG_ZLIB_DEFLATE=m
- build-essential: make, compiler, etc
- linux-headers-2.6.27-9-generic: latest kernel headers
sudo apt-get install build-essential linux-headers-2.6.27-9-generic
Patch: [2] Download, patch and compile code:
wget http://www.kernel.org/pub/linux/kernel/people/mason/btrfs/btrfs-0.17.tar.bz2 tar -jxvf btrfs-0.17.tar.bz2 cd btrfs-0.17 #apply patch make
Currently btrfs does not work with kernel 2.6.27 Ensure modules are up and running, and insert btrfs module into kernel.
sudo modprobe libcrc32c zlib_inflate zlib_deflate sudo insmod btrfs.ko
btrfs progs dependencies
sudo apt-get install e2fsprogs uuid-dev
wget http://www.kernel.org/pub/linux/kernel/people/mason/btrfs/btrfs-progs-0.17.tar.bz2 tar -jxvf btrfs-progs-0.17.tar.bz2 make
btrfs-progs compile fine
