Getting started with btrfs

  • Posted November 30, 2013

I would like to try using btrfs so that I can easily snapshot my application data before rolling out new versions. I don’t need my whole filesystem to be btrfs (as nice as that might be), one mount point (say, /data) would be fine.

Are there any guides for how to repartition disks in the context of Digital Ocean?


u can convert fs from recovery mode.

0 ur root fs should be ext4

  1. install btrfs-tools
  2. reboot to recovery mode
  3. mount ur disk and cp btrfs-convert to /
  4. umount disk
  5. btrfs-convert
  6. mount disk & chroot & edit fstab
  7. boot into default kernel

now u have btrfs as root fs

One solution would be to use btrfs with a loop device. Your data will be stored in a btrfs image file.

Note: I recommend you use a recent kernel version (4+). I use BTRFS on my personal system and things are mostly ok, some performance issues when databases/indexing happens. I’ve read that Facebook is preparing to roll it in production systems. The future is bright :)

Some notes:

Unfortunately we do not support partitioning yet.
