This needs to support older btrfs-progs versions though, so run btrfstune to check whether it has the -U parameter, and if not return the old error message. Something like test_btrfs_device_add_needs_force for example. Also: $ btrfs --version btrfs-progs v4.0 $

I''ve enabled "extended inode refs" and "skinny metadata extent refs" with btrfstune. Then, I''ve tried running "btrfs filesystem balance" - unfortunately it segfaulted. (not sure if I should run balance operation after using btrfstune with -r and -x)? This is with 3.10 kernel with "Btrfs: make backref walking code handle skinny metadata"

I''ve upgraded to linux 3.10 and enabled extended inode refs and skinny metadata extent refs with these commands: btrfstune -r /dev/sdc1 btrfstune -x /dev/sdc1 Since then, I have "WARNING: at fs/btrfs/backref.c:903 find_parent_nodes+0x616/0x815 [btrfs]()" showing up like crazy: # grep -c "WARNING: at fs/btrfs/backref.c:903" syslog 181819 That''s after just
