I have a problem when upgrading from 13.10 to 14.04: I have a triple boot (Mac 10.9 + Win 7 + 13.10) on a Macbook with a 120GB SSD. The Ubuntu is on sda6, btrfs, 15GB. GParted says 2,9GB are free, but Baobab sees only around 4GB occupied. Why is there such a huge difference? I do not have any subvolumes, and no snapshots as far as I can see. Any ideas?

Is it possible you're experiencing the same issue described in this (invalid) bug report?

I do not think so, Baobab reports the correct size on the main screen, just in the analysis screen it report less:
Output of
sudo btrfs filesystem show /dev/sda6
Label: none uuid: 82579bc5-a31c-478e-9ed6-4c3c3fd3566f
Total devices 1 FS bytes used 11.70GB
devid 1 size 14.90GB used 14.90GB path /dev/sda6

Btrfs v0.20-rc1
And of
sudo btrfs filesystem df /
Data: total=12.87GB, used=11.06GB
System, DUP: total=8.00MB, used=4.00KB
System: total=4.00MB, used=0.00
Metadata, DUP: total=1.00GB, used=658.52MB
Metadata: total=8.00MB, used=0.00
Any further ideas?

What is the output of:

df -h

If there are more than two old and unused kernels, that could take up the space needed for upgrade.
Removing unused kernels can help you reclaim some of the space.
You can check with sudo update-grub how many kernels you have and if you want to remove those then you can do so with?

sudo dpkg -l linux-* | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e [0-9] | xargs sudo apt-get -y purge

Not sure why bobab sees only what it sees... I've never used the tool before. Hopefully someone will clarify.

the output of df -h is:

Fájlrendszer Méret Fogl. Szab. Fo.% Csatol. pont
/dev/sda6 15G 13G 2,0G 87% /
none 4,0K 0 4,0K 0% /sys/fs/cgroup
udev 1,9G 4,0K 1,9G 1% /dev
tmpfs 387M 1,2M 386M 1% /run
none 5,0M 0 5,0M 0% /run/lock
none 1,9G 212K 1,9G 1% /run/shm
none 100M 44K 100M 1% /run/user
/dev/sda1 197M 16M 182M 8% /boot/efi
/dev/sda6 15G 13G 2,0G 87% /home
/dev/sda4 39G 29G 10G 74% /mnt/adat
I don't have unused kernels, I remove them when a new one comes out

df -h indicates that you are have totally 15GB, use 13GB and have 2GB free in the root partition.

Are there lots of files in the trashcan?
Are there lots of files in hidden directories?

Or could this be a problem because some tools are not working correctly with btrfs?

Since you don't have a separate '/home' partition your 'Home' is in '/' partition. It might help if you can make space in your 'Home'.
Apart from that I can't think of anything more than what sudodus has suggested.

shame on me: I did in fact have two snapshots from previous dist-updates, and those of course consumed up to 3-4GB each :D So deleted them an 14.04 updated like charm.
Thanks everybody and sorry for the distubance
