    Abstract: Embodiments of the present invention provide methods, apparatuses, systems, and computer software products for data storage. A corrupted node under a first meta-volume node in a hierarchical tree structure is deleted. The hierarchical tree structure further includes a source node under the first meta-volume node. The corrupted node and the source node each include a respective set of local pointers. The corrupted node and the source node represent respective copies of a logical volume. The source node is reconfigured to become a second meta-volume node having the same set of local pointers as the source node. A first new node is created under the second meta-volume node in the hierarchical tree structure to represent the corrupted node. A second new node is created under the second meta-volume node to represent the source node. The first and second new nodes are configured to have no local pointers.

    Abstract translation: 本发明的实施例提供用于数据存储的方法,装置,系统和计算机软件产品。 层次树结构中第一个元卷节点下的损坏的节点被删除。 分级树结构还包括第一元音量节点下的源节点。 损坏的节点和源节点每个都包含一组相应的本地指针。 损坏的节点和源节点表示逻辑卷的相应副本。 重新配置源节点以成为具有与源节点相同的本地指针集的第二元卷节点。 在分层树结构中的第二个元卷节点下创建第一个新节点来表示损坏的节点。 在第二个元卷节点下创建第二个新节点来表示源节点。 第一个和第二个新节点被配置为没有本地指针。
