DISTRIBUTED FILE SYSTEM IN A DISTRIBUTED DEDUPLICATION DATA STORAGE SYSTEM
First Claim
1. A networked information management system configured to automatically configure installed data storage computers, the networked information management system comprising:
- a first data storage computer comprising first computer hardware;
a first secondary storage device managed by the first data storage computer, wherein the first secondary storage device comprises a first hard disk and a second hard disk;
a second data storage computer comprising second computer hardware;
a second secondary storage device managed by the second data storage computer, wherein the second secondary storage device comprises a third hard disk and a fourth hard disk;
a third data storage computer comprising third computer hardware, wherein the third data storage computer is installed in the networked information management system after the first data storage computer and the second data storage computer;
a third secondary storage device managed by the third data storage computer, wherein the third secondary storage devices comprises a fifth hard disk and a sixth hard disk; and
a storage manager comprising computer hardware configured to;
detect that the third data storage computer is installed in the networked information management system,associate the first hard disk, the third hard disk, and the fifth hard disk such that the first hard disk, the third hard disk, and the fifth hard disk together store data for a first file system, andassociate the second hard disk, the fourth hard disk, and the sixth hard disk such that the second hard disk, the fourth hard disk, and the sixth hard disk together store data for a second file system,wherein the first data storage computer continues to receive input/output (I/O) requests for the second hard disk after a failure of the first hard disk.

Abstract
Systems and methods are provided herein for automatically configuring newly installed secondary storage computing devices and managing secondary storage computing devices when one or more become unavailable. For example, a storage manager can then detect the computing resources available to the newly installed secondary storage computing device, assign a role to the newly installed secondary storage computing device based on the detected computing resources, configure the newly installed secondary storage computing device with deduplication and storage policies used by the other secondary storage computing devices, re-partition secondary storage devices to allocate memory for the newly installed secondary storage computing device, and instruct other secondary storage computing devices to replicate their managed data such that the newly installed secondary storage computing device has access to the replicated data.
