It mounts without errors? So why then btrfsck/btrfs repair? What precipitated the repair?

If mount option -o recovery is used, dmesg should report 'btrfs: enabling auto recovery' and I think you're right if it's mounting OK then probably recovery isn't applicable. Can you just do a btrfs check <dev> and report the results? Repair can sometimes make problems worse it seems.
