Abstract: One or more techniques and/or systems are provided for mirror vote synchronization. For example, a first storage device is located at a first storage site, and a second storage device is located at a second storage site. The second storage device is configured according to a data mirroring configuration where data from the first storage device is mirrored to the second storage device. Mirror vote metadata is generated based upon an up-to-date state of the data mirroring configuration. The mirror vote metadata indicates whether the first storage device and/or the second storage device are up-to-date or not. The mirror vote metadata may be replicated between the first storage site and the second storage site. If the first storage site fails, then the second storage site may provide switchover operation using the second storage device based upon the mirror vote metadata.
Abstract translation: 提供一个或多个技术和/或系统用于镜像投票同步。 例如，第一存储装置位于第一存储部位，第二存储装置位于第二存储部位。 第二存储装置根据数据镜像配置配置，其中来自第一存储设备的数据被镜像到第二存储设备。 基于数据镜像配置的最新状态生成镜像元数据。 镜像表决元数据指示第一存储设备和/或第二存储设备是否是最新的。 可以在第一存储站点和第二存储站点之间复制镜像投票元数据。 如果第一存储站点发生故障，则第二存储站点可以基于镜像投票元数据使用第二存储设备提供切换操作。
