Instaleu o ubuntu 11.04 em uma partição btrfs, depois editei o fstab, agora ele esta assim:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
# / was on /dev/sda3 during installation
UUID=eec20bf8-7e00-410f-ab79-6f03cef46946 / btrfs compress=zlib,defaults,subvol=@ 0 1
# /boot was on /dev/sda5 during installation
UUID=9ac476a4-c963-41ce-85e2-8017d03173be /boot ext2 defaults 0 2
# /home was on /dev/sda3 during installation
UUID=eec20bf8-7e00-410f-ab79-6f03cef46946 /home btrfs compress=zlib,defaults,subvol=@home 0 2
# swap was on /dev/sda8 during installation
UUID=38e470d6-46a6-4894-af22-d86cc717840f none swap sw 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0

Como que eu faço para saber se os arquivos estão mesmo sendo compactados e como eu faço para compactar o resto dos arquivos que ja estavam ai antes de eu editar o fstab ?
