Now the FS-bytes-used also make sense as it is about the size of data that I've copied, but the per-device used space seems strange to me and the output of "df -h" is also hard to interpret: Filesystem Size Used Avail Use% Mounted on /dev/sda5 684G 79G 605G 12% /btrfs I would have understood if the "Used" field would have been 160GB or if "Avail" would have dropped to 520GB. I guess that I'll come to a point where Used will be 340GB and Avail will also be 340GB but I'll be getting No Space Left On Device errors? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
