An example method includes striping a volume across a plurality of storage nodes, and maintaining a cluster volume table (CVT) storing information regarding distribution of the logical blocks. Additionally, the CVT includes a plurality of entries, where each of the entries includes information identifying a respective owner storage node of a respective logical block. The method also includes receiving a write I/O operation directed to an unallocated logical block owned by a landing storage node, where the landing storage node lacks free storage capacity, and locking the unallocated logical block. The method further includes updating the CVT to identify a storage node having free storage capacity as owner storage node of the unallocated logical block, and unlocking the unallocated logical block, wherein the write I/O operation proceeds at the storage node having free storage capacity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for implementing space consolidation and space expansion in a horizontally federated cluster","description":"Systems and methods for handling input/output operations during a space crunch are described herein.
