The on-disk structure arranges file system data sequentially on disk within regions, wherein each region comprises a predetermined amount of disk space represented by blocks. The snapshot and file system metadata is maintained within level 1 (L1) indirect blocks of the on-disk structure. Each L1 indirect block describes (i.e., represents) a corresponding region of the on-disk structure of the file system; in the case of an active region, e.g., an L1 indirect block represents an active file data portion of a large file. The L1 indirect block that references an active region also performs file block number (fbn) to disk block number (dbn) mapping for the region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Maintaining snapshot and active file system metadata in an on-disk structure of a file system","description":"An on-disk structure of a file system has the capability to maintain snapshot and file system metadata on a storage system.
