Hi,
there's no information about reporting bugs in the btrfs wiki, so I try it
here.
For testing purposes, I have put all my Gentoo portage (build, distfiles, etc.)
related LVs into one 10G btrfs with 4 subvolumes.
While building OpenOffice yesterday, it failed with a "No space left on device"
error, although the LV was only 69% full in total.
Details (Builds of Gentoo packages happen in /gentoo/build.):
# mount|grep btr
/dev/mapper/gondolin-gentoo on /gentoo/build type btrfs (rw,subvol=build)
/dev/mapper/gondolin-gentoo on /gentoo/distfiles type btrfs

/dev/mapper/gondolin-gentoo on /gentoo/ccache type btrfs (rw,subvol=ccache)
/dev/mapper/gondolin-gentoo on /gentoo/overlays type btrfs
(rw,subvol=overlays)
# df -h |grep gentoo
