    Start:
    Sunday Sept 20, 9PM CDT GMT -5
    Duration of Maintenance: Up to 30 minutes
    Impact:
    Maintenance on Web3, Web4, LinSD1, MySQL1, MySQL2 will require the servers to be offline for up approx 30 minutes while we change out some hard disks in the storage array.
    While this storage is hotswap and should be able to be done live we have decided to take it offline and make the changes with it off due to a cascading issue in the past on a storage subsystem the with same design. We want to do all possible to minimize the downtime in this swap and it should be quite short, but we are planning up to 30 minutes just to make sure if any scheduled fsck runs it will have time to complete.

    Thanks for your patience and understanding.

    This maintenance is going now, we issued a shutdown to each VM, a couple being a little slow to stop.

    The maintenance work itself is done, we are waiting on web3 to be up fully before we call operation done. Web3 did a fsck and some fixes and now is checking quotas.
