Package: btrfs-tools
Version: 0.19-8
Severity: important


Hi,

I migrated from ext4 to btrfs using btrfs-convert. If I check the size of each partitions using df -h or btrfs-show, 
both of them give me wrong size of one of migrated partitions as shown below:

btrfs-show:
---------------------------------------------------------------------------------
Label: none  uuid: 08f9f21a-92b9-4fa8-936b-35f10a649d5e
        Total devices 1 FS bytes used 1.39GB
        devid    1 size 1.00GB used 1.00GB path /dev/mapper/linux_lvm-debian_home

Btrfs Btrfs v0.19
---------------------------------------------------------------------------------

df -h:
---------------------------------------------------------------------------------
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/linux_lvm-debian_home
                      1.0G  -64Z -428M 100% /home
---------------------------------------------------------------------------------

fsck.btrfs -f /dev/mapper/linux_lvm-debian_home :
---------------------------------------------------------------------------------
root 256 inode 257 errors 800
found 752316416 bytes used err is 1
total csum bytes: 617340
total tree bytes: 29261824
total fs tree bytes: 25804800
btree space waste bytes: 6544740
file data blocks allocated: 1356222464
 referenced 1311866880
Btrfs Btrfs v0.19
---------------------------------------------------------------------------------

As you can see, no correct info about partition size are given. Because even if it is a partition with
no space left, I am able to write there some files in total size of more than few tens of MB without any message
talking about no space left on device or something like that.  
Have a look below:

---------------------------------------------------------------------------------
pato@debian:~$ du -h tublatanka/
28M     tublatanka/
pato@debian:~$ cp tublatanka/ ./test -r 
pato@debian:~$ du -h tublatanka/ test/
28M     tublatanka/
28M     test/
---------------------------------------------------------------------------------


If more info would be needed, just ask, i'll be watching this bug. 

Thank you very much.

Hi,
your bug has been filed against the "linux-2.6" source package and was filed for
a kernel older than the recently released Debian 7.0 / Wheezy with a severity
less than important.

We don't have the ressources to reproduce the complete backlog of all older kernel
bugs, so we're closing this bug for now. If you can reproduce the bug with Debian Wheezy
or a more recent kernel from testing or unstable, please reopen the bug by sending
a mail to control@bugs.debian.org with the following three commands included in the
mail:

reopen BUGNUMBER
reassign BUGNUMBER src:linux
thanks

Cheers,
        Moritz
