description 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.
