I converted my ext4 volume to btrfs with success. Things seem to be working but there were many performance problems too. * btrfs-convert /dev/sda6 took almost 5 hrs to create the btrfs metadata for my 120G SATA HDD * After I boot into my newly converted btrfs / filesystem, df reports erratic. rrs@learner:~$ mount /dev/sda6 on / type btrfs (rw) tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) udev on /dev type tmpfs (rw,mode=0755) tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620) overflow on /tmp type tmpfs (rw,size=1048576,mode=1777) fusectl on /sys/fs/fuse/connections type fusectl (rw) rrs@learner:~$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda6 106G -64Z -54G 100% / tmpfs 1013M 0 1013M 0% /lib/init/rw udev 10M 244K 9.8M 3% /dev tmpfs 1013M 0 1013M 0% /dev/shm overflow 1.0M 0 1.0M 0% /tmp rrs@learner:~$ df -m Filesystem 1M-blocks Used Available Use% Mounted on /dev/sda6 108078 -72057594037764906 -54953 100% / tmpfs 1013 0 1013 0% /lib/init/rw udev 10 1 10 3% /dev tmpfs 1013 0 1013 0% /dev/shm overflow 1 0 1 0% /tmp On another test device, where an mkfs.btrfs was done, the space utilization was shown correctly.
