Isn't that too pessimistic? Most of my filesystems have 90+% of free space unallocated, even those I never run balance on. For me it wouldn't just spread the cost, it would reduce it considerably. -- 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
