But I still think it's a worse problem to not report anything at all in btrfs fi df, considering the historical point of df is to show space available. And it's also not good that the regular df shows e.g. for raid1, twice the free space as the amount of data that can be saved to the volume. > > Chris Murphy-- > 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 -- 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
