Abstract
A technique for managing a file system includes dividing the addressable space of a file system into multiple subspaces: a data subspace for user data; an inode subspace for inodes describing the user data; and an MDB (metadata block) subspace for indirect blocks and/or directory structures pertaining to the user data. In response to storage requests to write user files to the file system, the file system stores user data of the files in the data subspace, stores inodes pertaining to the user files in the inode subspace, and stores indirect blocks and/or directories in the MDB subspace.
