Abstract: Method and system for replacing a first node and a second of a clustered storage system by a third node and a fourth node are provided. The method includes migrating all storage objects managed by the first node to the second node; replacing the first node by the third node and migrating all the storage objects managed by the first node and the second node to the third node; and replacing the second node by the fourth node and then migrating the storage objects previously managed by the second node but currently managed by the third node to the fourth node. The nodes may also be replaced by operationally connecting the third node and the fourth node to storage managed by the first node and the second node; joining the third node and the fourth node to a same cluster as the first node and the second node.

Abstract translation: 提供了用于由第三节点和第四节点替换集群存储系统的第一节点和第二节点的方法和系统。 该方法包括将由第一节点管理的所有存储对象迁移到第二节点; 由第三节点替换第一节点并将由第一节点和第二节点管理的所有存储对象迁移到第三节点; 并且由第四节点替换第二节点，然后将先前由第二节点管理但是当前由第三节点管理的存储对象迁移到第四节点。 也可以通过将第三节点和第四节点可操作地连接到由第一节点和第二节点管理的存储来替换节点; 将第三节点和第四节点加入与第一节点和第二节点相同的簇。
