Reading the documentation about durability and repair[1], it appears data corruption should only ever occur if you had a hardware failure, or the mongodb process crashed or was killed. Was the data corruption you experienced because of any of these reasons? In your experience, how easy is it to repair a node vs switch to a replica node and rsynch. (I'm quite ignorant about MongoDB replication but in my idealised mind, it should be possible to recover a corrupted node entirely automatically and transparently to the client).
