Abstract: During a storage redundancy giveback from a first node to a second node following a storage redundancy takeover from the second node by the first node, the second node is initialized in part by receiving a node identification indicator from the second node. The node identification indicator is included in a node advertisement message sent by the second node during a giveback wait phase of the storage redundancy giveback. The node identification indicator includes an intra-cluster node connectivity identifier that is used by the first node to determine whether the second node is an intra-cluster takeover partner. In response to determining that the second node is an intra-cluster takeover partner, the first node completes the giveback of storage resources to the second node.
Abstract translation: 在从第一节点从第二节点接收存储冗余之后，从第一节点到第二节点的存储冗余中，第二节点通过从第二节点接收节点识别指示符而被初始化。 节点识别指示符包括在由存储冗余回授的回馈等待阶段由第二节点发送的节点通告消息中。 节点识别指示符包括簇内节点连接性标识符，第一节点使用该标识符来确定第二节点是否是集群内收购伙伴。 响应于确定第二节点是群内接管伙伴，第一节点完成对第二节点的存储资源的回馈。

Abstract: One or more techniques and/or systems are provided for controlling restoration of a storage aggregate. For example, a local storage device, located at a first storage site, and a remote storage device, located at a second storage site, may be assigned to a first storage aggregate. Responsive to a disaster of the first storage site, a gate may be created for the local storage device. The gate may block automated reconstruction and/or automated synchronization that may otherwise occur with respect to the local storage device. Until the local storage device is restored, the remote storage device may be used to service I/O requests that were otherwise directed to the local storage device. Responsive to receiving a user restoration command, the gate may be removed from the local storage device. Synchronization between the local storage device and the remote storage device may then be facilitated.
