Before the balance operation here is the df result: inglor@tiamat ~$ btrfs fi df /home Data: total=19.19GB, used=9.34GB System, DUP: total=32.00MB, used=4.00KB Metadata, DUP: total=896.00MB, used=227.98MB Then I issues a balance operation relocating the chunks across a single device: inglor@tiamat ~$ sudo btrfs fi balance /home [sudo] password for inglor: Done, had to relocate 28 out of 28 chunks After I did another df: inglor@tiamat ~$ btrfs fi df /home Data: total=10.00GB, used=9.34GB System, DUP: total=32.00MB, used=4.00KB Metadata, DUP: total=384.00MB, used=226.80MB Anyone can explain me the Data row of the above output ? It used to be 19.19GB and now it's 10.00GB. It's like the partition shrunk!? The balance operation finished without issues. Here's some other information: inglor@tiamat ~$ sudo btrfs filesystem show Label: 'home' uuid: 458c70e2-7037-4c4d-bba2-3d5288f04510 Total devices 1 FS bytes used 9.56GB devid 1 size 21.00GB used 10.81GB path /dev/sda3 Label: none uuid: 699d671b-7064-441d-95ec-c616049fe287 Total devices 1 FS bytes used 13.94GB devid 1 size 20.00GB used 20.00GB path /dev/sda2 Btrfs v0.20-rc1-358-g194aa4a-dirty inglor@tiamat ~$ df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda2 20971520 15362816 3960288 80% / /dev/sda3 22020096 10256168 11375416 48% /home Thanks, Leonidas -- Caution: breathing may be hazardous to your health. #include int main(){printf("%s","\x4c\x65\x6f\x6e\x69\x64\x61\x73");}
