I'm not recommending that you use btrfs check, just staying this version of tools is not reliable for some file systems. > btrfs fi df /mnt/btrfs-raid/ > Data, RAID1: total=6.17TiB, used=6.05TiB > System, RAID1: total=32.00MiB, used=916.00KiB > System, single: total=4.00MiB, used=0.00B > Metadata, RAID1: total=10.00GiB, used=8.14GiB > GlobalReserve, single: total=512.00MiB, used=0.00B The 3rd line is possibly rather dangerous in that it might mean there's some tiny amount of system data that has only one copy on one drive. And since it's a system chunk, if it's true that there's only one copy, if it were damaged or lost, it'd take out the whole volume. btrfs balance start -mconvert=raid1,soft <mp> See what that gets you, and then recheck with btrfs fi df or better use btrfs fi us. Unfortunately I don't have an answer for the original question. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
