Just be careful with LIMIT x on your servers if you have replicated mysql databases.  At least under older versions of mysql this can lead to broken replication as the results of the query performed on the master and on the slave are not guaranteed to be the same.

    Yep.  Both options basically require direct interaction with the 
    database as opposed to via a Cinder API call, but at least with 
    cinder-manage the scope for making a mistake is far more limited than 
    missing some qualifying clause off an UPDATE statement (limit 1 is your 
    friend!) ;)
