Systems and methods for consolidating space in a storage cluster are described herein. An example method can include striping a volume across a plurality of storage nodes, and maintaining a cluster volume table (CVT) storing information regarding distribution of a plurality of logical blocks across the storage nodes. The CVT can include a plurality of entries, where each of the entries can include information identifying a respective owner storage node of a respective logical block. The method can also include adding a new storage node to the storage cluster, and transferring data for one or more logical blocks from each of the storage nodes to the new storage node based on respective usage ratios of the storage nodes. The method can further include updating the CVT to identify the new storage node as owner storage node of the one or more logical blocks transferred to the new storage node.
