I use Btrfs accessed via NBD over a LAN, physically stored on mdadm RAID5, a

There may be others, but I haven't seen them active on-list. For active

Hi Liu,
Thanks for your work.
Each test copy 2gb file from sdf (btrfs) to sde (btrfs with dedup 4k
blocksize).
Before every test i recreate filesystem.
On second write all goods.
Test 1
Nodesize = leafsize = 4k
Write overhead ~ x1.5
Test 2
Nodesize = leafsize = 16k

I have a multiboot PC with Centos 6.5, Fedora 20, and Ubuntu 13.10.
Also there is a btrfs partition I want to mount, read and write from the
3 diferent distros.
Is this "safe" ? Is the btrfs versions from this 3 distros compatible
between them ?
This is for testing and learning only.
Thanks.

One way to get an idea of where that's happening is to run the command with

Btrfs send/receive can transfer incremental snapshots as well - you're

not be the right tool for the job.

Hi,
I was asked about situations "use cases" that would cause BTRFS to slow down
to a crawl.
And it's exactly what happened to me yesterday when I was trying, on the
contrary, to speed it up.
So here's the recipe for getting a "slow to the point it is unusable" BTRFS.

Hello,
(Still in my quest for BTRFS performance)
It is extremely unclear which BTRFS mount options are "filesystem wide" and
will apply to each and every mountpoint in the BTRFS filesystem, and which
options can be set per subvolume or per mountpoint.
As far as I can tell, there is no reliable
