In one example, a data storage device includes a first storage zone, a shingled magnetic recording (SMR) zone, and a storage control system. The storage control system is configured to maintain file system metadata in a metadata location of the first storage zone for user data in the SMR zone. The storage control system is further configured to, responsive to a usage condition being satisfied for the file system metadata in the metadata location, identify metadata locations in the SMR zone to redirect and store the file system metadata. The storage control system is also configured to maintain an indirection data structure in the metadata location of the first zone that correlates the metadata locations in the SMR zone to the file system metadata."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Indirection data structures to manage file system metadata","description":"Described herein are systems, methods, and software to manage file system metadata in a data storage device.
