Would it be sufficient for your usecase to print the % values in the 'btrfs fi usage' command? After the summary, the's listing of the chunks with the same values and slightly different format: Data,single: Size:296.00GiB, Used:166.99GiB Metadata,single: Size:5.00GiB, Used:2.74GiB System,single: Size:32.00MiB, Used:48.00KiB For reference, this is from 'fi df': Data, single: total=296.00GiB, used=166.99GiB System, single: total=32.00MiB, used=48.00KiB Metadata, single: total=5.00GiB, used=2.74GiB GlobalReserve, single: total=368.48MiB, used=0.00B I'd rather not extend the output of 'fi df' as this was supposed to be a debugging tool and 'fi usage' is gives better and more complete overview, so the % seem more logical to be put there.
