| 发明名称 | Scrubbing procedure for a data storage system | ||
| 摘要 | A method is provided for scrubbing information stored in a data storage system where the information is stored as a plurality of encoded fragments across multiple storage devices. The method includes maintaining on a first storage device a list of metadata entries corresponding to values that are stored in the data storage system at an At Maximum Redundancy (AMR) state, verifying that encoded fragments associated with each of the metadata entries are stored on a second storage, verifying that a corresponding metadata entry is stored on the first storage device for each encoded fragment that is stored on the second storage device, and scheduling for recovery any missing encoded fragments and/or any missing metadata entry. | ||

| 主权项 | 1. A method of scrubbing information stored in a data storage system, comprising: maintaining on a first storage device a list of metadata entries corresponding to values that are stored in the data storage system at an At Maximum Redundancy (AMR) state, where each of the values is divided into encoded fragments; verifying that the encoded fragments corresponding to each of the metadata entries are stored on a second storage device; verifying that a corresponding metadata entry is stored on the first storage device for each of the encoded fragments that are stored on the second storage device; and scheduling for recovery any missing encoded fragments and/or any missing metadata entry. | ||
