    Wow, where was everyone? I was there from about 5:15 and only found two others.

    I have a specific error I want to understand related to when I shut down a secondary in my replica set in one shard. I get tons of "code = 11002". Which basically means getLastError failed when sent to the secondary. We are running a sharded mongodb 2.4 cluster. What is the best practice of upgrading a replicaset shard? We are using autoscaling groups in aws so it's all semi-automatic. Currently I would:
    1. rs.remove the secondary
    2. db.shutdownServer that secondary
    AWS will kill that node and once the other one is brought back up as a secondary and catches up with replication
    3. I proceed to run rs.stepDown(120) on the primary and then repeat steps 1 and 2 on this "new" secondary.

    I plan to come to the office hours but if anyone has any guidance it would be much appreciated. Apologies if this is an inappropriate forum for the question. Thanks,
    mike
