Hallo, Hugo, Du meintest am 06.12.10: >>> After running "balance" it looks better: >>> Label: 'MM2' uuid: ad7c0668-316c-4a79-ba00-3b505b9d99b4 >>> Total devices 2 FS bytes used 2.39TB >>> devid 2 size 1.35TB used 1.20TB path /dev/sdc3 >>> devid 1 size 1.81TB used 1.20TB path /dev/sdf2 >> >> And now: >> >> Filesystem 1K-blocks Used Available Use% Mounted on >> /dev/sdc3 3400799848 2569770888 831028960 76% /srv/MM >> >> But after copying about 300 MByte (part of a 1.5-GByte *.mpg) I got >> "no space left on device".

I've just written a script for gathering the (perhaps) interesting data ... # btrfs filesystem show Label: 'MM2' uuid: ad7c0668-316c-4a79-ba00-3b505b9d99b4 Total devices 2 FS bytes used 2.37TB devid 2 size 1.35TB used 1.20TB path /dev/sdc3 devid 1 size 1.81TB used 1.20TB path /dev/sdf2 Btrfs Btrfs v0.19 # btrfs filesystem df /srv/MM Data: total=2.39TB, used=2.37TB Metadata: total=5.25GB, used=3.51GB System: total=12.00MB, used=188.00KB # df -t btrfs Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/sdc3 btrfs 3400799848 2547059672 853740176 75% /srv/MM # fdisk -l /dev/sdc3 1569 182401 1452541072+ 83 Linux /dev/sdf2 655 243201 1948258777+ 83 Linux # ---------------------------------------- I've moved about 50 Gbyte away from "srv/MM" in the meantime, before running the script with this output. And I don't dare running "balance" again - maybe it reduces the available space again and again. Viele Gruesse!
