The target DSS assesses a migration state of a user file of the user I/O operation, including (1) determining whether a metadata file storing migration state data for the user file has an already recovered record indicating the migration state of the file, (2) if so, then using the already recovered record to assess the migration state of the user file, and (3) otherwise (a) initiating an on-demand recovery to obtain an on-demand record for the user file, and (b) using the on-demand recovered record to assess the migration state. If the migration state indicates that the file has not yet been migrated, then the user I/O operation is redirected to a separate source DSS, and otherwise the user I/O operation is completed locally at the target DSS."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data storage system with on-demand recovery of file import metadata during file system migration","description":"A user I/O operation is processed in a file system of a target data storage system (DSS) performing a file system migration.
