Note: I already filed bug 121071 but perhaps I should have written to this mailing list first. I get the ENOSPC error when running a btrfs full balance command for my root partition, even if it seems I have a lot of free/unallocated space. # btrfs filesystem show / Label: none uuid: 27150b83-7d90-4031-8e83-581315b9a254 Total devices 1 FS bytes used 10.79GiB devid 1 size 25.00GiB used 13.31GiB path /dev/mapper/Desktop-root # btrfs filesystem df / Data, single: total=11.00GiB, used=10.40GiB System, DUP: total=32.00MiB, used=16.00KiB Metadata, DUP: total=1.12GiB, used=392.08MiB GlobalReserve, single: total=144.00MiB, used=0.00B # btrfs balance start --full-balance / ERROR: error during balancing '/': No space left on device There may be more info in syslog - try dmesg | tail # dmesg | tail [29807.441930] BTRFS info (device dm-2): found 13206 extents [29807.879845] BTRFS info (device dm-2): relocating block group 47542435840 flags 1 [29827.116083] BTRFS info (device dm-2): found 12909 extents [29830.500110] BTRFS info (device dm-2): found 12909 extents [29830.976485] BTRFS info (device dm-2): relocating block group 46468694016 flags 1 [29848.924188] BTRFS info (device dm-2): found 5129 extents [29851.533076] BTRFS info (device dm-2): found 5129 extents [29851.994787] BTRFS info (device dm-2): relocating block group 46435139584 flags 34 [29852.399460] BTRFS info (device dm-2): found 1 extents [29852.657983] BTRFS info (device dm-2): 1 enospc errors during balance I have successfully balanced both the boot and home partitions before. Only root gives me problems. Is there anything I can try? Should I run the command from a live CD? Is this a real bug or a mistake from an unexperienced btrfs user like me?
