Well... here we go: # btrfs qgroup show . Qgroupid Referenced Exclusive Path=20 -------- ---------- --------- ----=20 0/5 16.00KiB 16.00KiB 0/257 39.48GiB 39.48GiB data 0/258 16.00KiB 16.00KiB 0/259 16.00KiB 16.00KiB a 0/260 16.00KiB 16.00KiB b 1/100 32.00KiB 32.00KiB <0 member qgroups> 1/101 0.00B 0.00B <0 member qgroups> I've just created a and b to get qgroup (somehow? ^^) working. Nevertheless: I'm 100% sure, that before, there were never any subvolumes on that fs other than the toplevel and data, unless btrfs somehow creates/deletes them automatically. But the above output, AFAIU, still shows that "everything" is in data, while counting the bytes of files there, still yields a much lower number. And other ideas what I could test? Thanks, Chris.
