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 a few hours of uptime.
I guess that's not expected?
Some examples:
