IMO it has more pro's than con's

BTW, I never had btrfs data corruption under normal condition [1], and I'm using btrfs on nearly all my systems

Quote:When i remember correct "feature 10" was the lz4-compression for btrfs in the kernel.

Don't know

Quote:I fixed that by building my own kernel with that support:

(4.4.14-btrfs01 #1 SMP PREEMPT Sat ...)

Yes, I remember this thread

Quote:Yesterday i downloaded the latest image for xbian and made a dd to an usb-stick, because i thought it i also using the latest firmware to be able to boot the rpi3 via usb.

???

Quote:I was wondering, that kernel 4.4.0-34-lowlatency in ubuntu-studio was also able to mount that btrfs-partitition.

Did you or ubuntu changed something with the btrfs-stuff?

OC, no change. This is normal, image is build with lzo compression, compression is set to lz4 in /boot/cmdline.txt only
So, if you do not like to use lz4, you can change this before you boot that image the first time

Quote:btw. this is not the first time that xbian crashed with a btrfs error but the first time with an "nearly" productive system

Seems there is going something wrong with your system. Maybe you have to change sd-card. When I got first RPi2, I struggled a long time with heavy system instability. After I changed everything I could change (I used 3 identical brand new sd-cards from samsung) I bought another one (from samsung too, but latest EVO model), and after this all problems were gone.

Quote:Never got these problems on raspian (wheezy) on the PI-B nor on ubuntu (xenial) on the Pi-3

[1]
-I got btrfs fs crash some years ago on one of my systems I was undervolting CPU and this did not like btrfs.
-I got another btrfs crash about one year ago on my notebook because of too aggressive power saving settings and too old and buggy kernel (was 3.14)

That's all, never had critcal btrfs errors on my 5 XBian devices (2 of them are used for developing)
