    Stop encrypted disk on instance suspend/power off
    
    Disconnecting dm-crypt device from an encrypted LVM volume while the
    instance is suspended or powered off will secure user data from
    unauthorized access. This will extend data at-rest protection provided
    by the LVM ephemeral storage encryption feature.
