Josef's server parks is a bit of a different use case than laptops as
other people has already pointed out.
If you want data on how it works in a desktop/laptop scenario talk to
openSUSE users about how many times the "btrfs randomly ate my
volume"-bug was "fixed".
When I ran an environment of about 4500 SLES and about 5000 RHEL
servers btrfs failed about 3 times as often as xfs (this from our own
in-house statistics). That was 3 years ago but filesystems takes long
to mature and I have been keeping ear near openSUSE to see where it
Is this as big as Josef's environment? No but it is first hand data
to me (to you it is of course just anecdotal evidence)
Keep in mind that SLES does backport btrfs patches because they support
it. RHEL does not. And we are talking about Fedora here anyway.
BTRFS has the potential to become great, I just think it isn't
yet and it'll take 5 years of smooth sailing to convince me.
Probably you should try it with Fedora's kernel?
