Fine. This openSUSE with snapper which creates and automatically destroys snapshots and apparently either kernel or snapper now also remove corresponding qgroup. I played with snapshots and created several top level qgroups that included snapshot qgroups existing at this time. Now these snapshots are gone, their qgroups are gone ... and what can I do? I have no way to even know what is wrong because the very command that shows it fails immediately. bor@tw:~/python-btrfs/examples> sudo ./show_tree_keys.py 8 . | grep 0/789 (0/789 QGROUP_RELATION 2/792) (0/789 QGROUP_RELATION 2/793) (0/789 QGROUP_RELATION 2/795) (0/789 QGROUP_RELATION 2/799) (0/789 QGROUP_RELATION 2/800) (0/789 QGROUP_RELATION 2/803) (0/789 QGROUP_RELATION 2/804) (0/789 QGROUP_RELATION 2/805) (0/789 QGROUP_RELATION 2/806) (0/789 QGROUP_RELATION 2/807) (0/789 QGROUP_RELATION 2/808) (0/789 QGROUP_RELATION 2/809) (0/789 QGROUP_RELATION 2/814) (0/789 QGROUP_RELATION 2/818) (0/789 QGROUP_RELATION 2/819) (2/792 QGROUP_RELATION 0/789) (2/793 QGROUP_RELATION 0/789) (2/795 QGROUP_RELATION 0/789) (2/799 QGROUP_RELATION 0/789) (2/800 QGROUP_RELATION 0/789) (2/803 QGROUP_RELATION 0/789) (2/804 QGROUP_RELATION 0/789) (2/805 QGROUP_RELATION 0/789) (2/806 QGROUP_RELATION 0/789) (2/807 QGROUP_RELATION 0/789) (2/808 QGROUP_RELATION 0/789) (2/809 QGROUP_RELATION 0/789) (2/814 QGROUP_RELATION 0/789) (2/818 QGROUP_RELATION 0/789) (2/819 QGROUP_RELATION 0/789) bor@tw:~/python-btrfs/examples> And even if I find it out, I cannot fix it anyway bor@tw:~/python-btrfs/examples> sudo btrfs qgroup remove 0/789 2/792 .
