I have two 3TB drive that are formated as btrfs and mounted on /media/andy/btrfs as one drive.I run btrfs balance start -dconvert=raid1 -mconvert=raid1 /media/andy/btrfs/ which takes forever.It outputs ERROR: error during balancing '/media/andy/btrfs/' - Input/output error There may be more info in syslog - try dmesg | tailThere's an output there, it's very long.Sure enough, I try btrfs filesystem df /media/andy/btrfsI getData, RAID1: total=1.14TiB, used=1.13TiBData, single: total=106.01GiB, used=94.40GiBSystem, DUP: total=8.00MiB, used=184.00KiBSystem, single: total=4.00MiB, used=0.00BMetadata, RAID1: total=1.00GiB, used=1017.65MiBMetadata, DUP: total=1.00GiB, used=441.45MiBMetadata, single: total=8.00MiB, used=0.00BGlobalReserve, single: total=488.00MiB, used=0.00BSo sure enough I have 106 GiB that's not in raid. Anyone has an idea how to fix this? I'm running Debian testing. Kernel 3.16.7
