Abstract
A method for upgrading a file system in a data storage environment is provided. A storage system identifies a set of boundaries of one or more sets of hard disks based on a first block management data structure (BMDS), where the first BMDS includes information describing a storage volume representing the one or more sets of hard disks. For each identified boundary, the storage system identifies a data block range of a set of data blocks, where the data block range includes metadata of one set of hard disks that is stored on the set of data blocks. Further, the storage system concurrently generates a plurality of second BMDSs, each of the second BMDS corresponding to one of the sets of hard disks, including simultaneously retrieving metadata of the sets of hard disks, where the second BMDSs are constructed based on the retrieved metadata, representing an upgraded file system.
