Hi,

I'm using btrfs for my /usr/share/ partition and keep getting the following error while installing a debian package which should take no more than 228 MB:

Unpacking texlive-fonts-extra (from .../texlive-fonts-extra_2009-10ubuntu1_all.deb) ...
dpkg: error processing /var/cache/apt/archives/texlive-fonts-extra_2009-10ubuntu1_all.deb (--unpack):
unable to install new version of `/usr/share/texmf-texlive/fonts/type1/public/allrunes/frutlt.pfb': No space left on device

However df reports plenty of available space:

/dev/mapper/vg0-usr_share

                      5.0G  1.5G  2.5G  37% /usr/share

I already extended /dev/mapper/vg0-usr_share from 4G to 5G and ran defrag and balance on it with no luck. I'm using ubuntu 11.10 on amd64 with the ubuntu 3.0.0 kernel.

btrfs reports to use "zlib compression".

Is this a known problem with compressed btrfs?

Best regards
Arnd

JFYI: the problem went away in 3.2-rc2 so someone must have fixed something.

Thanks!

I just experienced the same thing in Ubuntu precise, 3.2.0-17-generic, so I don't think it's fixed yet.

$ sudo btrfs fi df /

the problem occur when copying precise lxc root template (322M, 13759 files/directories).

It only happens when using zlib compression though, using lzo works fin= e.
