Output of show_usage.py: https://gist.githubusercontent.com/ojab/850276af6ff3aa566b8a3ce6ec444521/raw/4d77e02d556ed0edb0f9823259f145f65e80bc66/gistfile1.txt Looks like I only have smaller spare drives at the moment (largest is 100GB), is it ok to use? Or there is some minimal drive size needed for my setup? //wbr ojab -- 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
