I suspect there are snapshots taking up space that are no located in the search path starting at / What do you get for: $ sudo btrfs sub list -ta / Is this an openSUSE system? If snapper is enabled, you'll need to ask it to delete some of the snapshots to free up space rather than doing it with btrfs user space tools. > alian:/ # btrfs fi df / > Data, single: total=35.00GiB, used=34.18GiB > System, DUP: total=32.00MiB, used=16.00KiB > Metadata, DUP: total=384.00MiB, used=216.75MiB > GlobalReserve, single: total=22.05MiB, used=0.00B > > I try to run btrfs balance multiple time with various parameters but > it doesn't change anything nor trying btrf check in single user mode. > > Where is my 30 Go missing ? -- Chris Murphy
