New information guys! I formatted using the latest Tumbleweed snapshot (btrfs-progs v4.7+20160729) and I still have the same problem. I notice two things. First, when I see the "No space left on device", it is fixed when the Metadata space increases **a lot**. For example, when the error first occurred, I had: Metadata, DUP: total=2.00GiB, used=811.52MiB After waiting a while (could not run balance), it was automatically fixed and then I have: Metadata, DUP: total=9.50GiB, used=811.52MiB During the error, when I ran the balance command, I see these messages in `dmesg`: Ago 22 16:00:03 ronanarraes-osd kernel: BTRFS info (device sda6): relocating block group 9323937792 flags 34 Ago 22 16:00:04 ronanarraes-osd kernel: BTRFS info (device sda6): found 1 extents Ago 22 16:00:04 ronanarraes-osd kernel: BTRFS info (device sda6): 1 enospc errors during balance Ago 22 16:00:24 ronanarraes-osd kernel: BTRFS info (device sda6): relocating block group 36201037824 flags 34 Ago 22 16:00:24 ronanarraes-osd kernel: BTRFS info (device sda6): 2 enospc errors during balance Ago 22 16:00:45 ronanarraes-osd kernel: BTRFS info (device sda6): relocating block group 36234592256 flags 34 Ago 22 16:00:46 ronanarraes-osd kernel: BTRFS info (device sda6): found 1 extents Ago 22 16:00:46 ronanarraes-osd kernel: BTRFS info (device sda6): 4 enospc errors during balance Ago 22 16:01:20 ronanarraes-osd kernel: BTRFS info (device sda6): relocating block group 38415630336 flags 34 Ago 22 16:01:21 ronanarraes-osd kernel: BTRFS info (device sda6): found 1 extents Ago 22 16:01:21 ronanarraes-osd kernel: BTRFS info (device sda6): 8 enospc errors during balance Does it add anything relevant to the problem?
