I'm trying to remove some files on a btrfs filesystem which has 26 GB free:

/dev/sdb4             336G  310G   26G  93% /mnt/btrfs


Unfortunately, removing some of the files fails, due to "No space left on device":

root@dom:/mnt/btrfs# rm -rfv postgresql-noindex
removed `postgresql-noindex/postgresql/8.4/main/base/16384/16508.6'
removed `postgresql-noindex/postgresql/8.4/main/base/16384/16508.7'
rm: cannot remove `postgresql-noindex/postgresql/8.4/main/base/16384/16508.8': No space left on device
removed `postgresql-noindex/postgresql/8.4/main/base/16384/16508.9'
removed `postgresql-noindex/postgresql/8.4/main/base/16384/16508_fsm'
removed `postgresql-noindex/postgresql/8.4/main/base/16384/16511'
removed `postgresql-noindex/postgresql/8.4/main/base/16384/16513'
removed `postgresql-noindex/postgresql/8.4/main/base/16384/16516'
removed `postgresql-noindex/postgresql/8.4/main/base/16384/16516_fsm'
removed `postgresql-noindex/postgresql/8.4/main/base/16384/16521'

This is a snapshot of a different directory (with some changes).

Is it expected? I'm running 2.6.39.1 kernel.
