Just take a look at the official Gotchas Page of BTRFS, which can be |

found here: |

Putting virtual image files on Btrfs is something that the developers |
16 |
still do not recommend at all, and that's with reason! |

If you really do want to put them up a COW filesystem, you should try |
19 |
ZFS on Linux instead, otherwise go with XFS or ext4 - in that kind of |
20 |
order. |

Frankly said, Btrfs in my humble opinion is just not ready for prime |
23 |
time yet and will not be for a couple of year and if you really do want |
24 |
a COW filesystem now, you should take a look at ZFS instead. |
