    Abstract: A storage object is migrated between nodes by a source node automatically verifying that another node is configured to service the storage object and changing ownership of the storage object based on the verifying. A cluster manager for the clustered storage system receives a request and provides the request to the source which owns the storage object. The source verifies that the destination is configured according to a predetermined configuration for servicing the storage object. Based on the verifying, the source offlines the storage object and updates ownership information of the storage object, thereafter allowing the destination to online the storage object. The cluster manager further provides the updated ownership information to all the nodes in the cluster, so an access request intended for the storage object may be received by any node and forwarded to the destination using the updated ownership information to effect a transparent migration.

    Abstract: A system and method of negotiated takeover of storage objects includes one or more processors, a storage controller, and memory coupled to the one or more processors. The memory stores a data structure that includes information about a plurality of storage objects manageable by the storage controller. The storage controller is configured to assume, one by one, current ownership of a first subset of the storage objects and assume, concurrently, current ownership of a second subset of the storage objects. The first subset of storage objects and the second subset of storage objects are currently owned by a second storage server coupled to the storage server. In some embodiments, current ownership of the first subset of storage objects is transferred by iteratively detecting a particular storage object from the first subset of the storage objects whose current ownership can be assumed and bringing the particular storage object online.

    Abstract translation: 协商接管存储对象的系统和方法包括耦合到一个或多个处理器的一个或多个处理器，存储控制器和存储器。 存储器存储包括关于由存储控制器可管理的多个存储对象的信息的数据结构。 存储控制器被配置为逐个地假设存储对象的第一子集的当前所有权并同时假设存储对象的第二子集的当前所有权。 存储对象的第一子集和存储对象的第二子集目前由耦合到存储服务器的第二存储服务器所拥有。 在一些实施例中，存储对象的第一子集的当前所有权通过迭代地从存储对象的第一子集迭代地检测特定存储对象来传送，该存储对象的当前所有权可以被假设并且使特定存储对象在线。
