Here the requested information of my fs (after removing a lot of build
directories):
franzbroetchen# uname -a
Linux franzbroetchen 4.0.0-1-amd64 #1 SMP Debian 4.0.2-1 (2015-05-11)

=0 but it didn't help. The metadata size stayed at 10G and was
filled up to nearly 10G.
My question is: Can this metadata size limit be changed to allow more
small files on the filesystem? And if yes, how?
According to the kernel btrfs documentation, metadata_ratio= is
currently off by default. So
is the metadata. I've tried to run the balance command with
-dusage=0 but it didn't help. The metadata size stayed at 10G and was
filled up to nearly 10G.
Try with -dusage=5, or with -dlimit=3.
The kernel should be automatically freeing up completely empty
chunks (i.e. usage=0), so
Hi guys,
My Btrfs fs has a performance problem which I hope you can help me
solve. I have a dataset of around 3.15 TiB, that has lived on a ZFS
volume for almost two years (ZRAID1, 4 2TiB disks). In order to move
to Btrfs I bought myself a 4TiB disk with the idea of buying a new one
next week and
I use Ubuntu with kernel 3.8.0-19-generic. I also tested with the
latest live disk of Arch Linux; write performance was the same (bad).
My mount options: rw,compress=lzo.
Iotop does not show any strange disk activity.

and the metadata size also grew. No problems in that department
either. ;-)

Because performance was good again I was able to spam the volume with
data and the metadata size also grew. No problems in that department
either. ;-)

There is a lot of good information at the wiki and it does see regular
updates. For example the performance mount options are on this page:

space_cache is the default, set by mkfs, for a year or so now. It's
sticky, so even if it wasn't, you'd only need to mount with it once.

Did you try balance ? (also there is a balance option
to pick the least utilized metadata chunks).
in long run when you have the understanding of your
files and sizes tuning using mount option metadata_ratio
might help.
but not sure how the metadata expanded to 84.38G
was there any

I'm a little concerned about the size of my metadata. I'm doing
