A set of logical addresses in a mapping table is partitioned into subsets of logical addresses. Each of the subsets of logical addresses is assigned to respective processor cores in the data storage system. Each of the processor cores is configured to check each logical address of the assigned subset of logical addresses in the mapping table for a valid physical address mapped to the logical address, for each valid physical address mapped to a logical address of the assigned subset of logical addresses, increment a validity count in a local validity table associated with a blockset of the non-volatile memory corresponding to the valid physical address, and update validity counts in a global validity table associated with respective blocksets of the non-volatile memory with the validity counts in the local validity table."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Recovery of validity data for a data storage system","description":"The subject technology provides for recovering a validity table for a data storage system.
