| 发明名称 | Caching rebuilt encoded data slices in a dispersed storage network | ||
| 摘要 | A method begins with a processing module of a computing device of a dispersed storage network (DSN) executing a rebuild function to produce a rebuilt encoded data slice for storage in a targeted storage unit of the DSN. When the targeted storage unit is currently unavailable, the method continues with the processing module storing the rebuilt encoded data slice in local memory of the computing device, recording storage of the rebuilt encoded data slice in the local memory, and recording that the targeted storage unit is currently unavailable. When the targeted storage unit is currently available, the method continues with the processing module sending the rebuilt encoded data slice to the targeted storage unit and recording storage of the rebuilt encoded data slice by the targeted storage unit. | ||

| 主权项 | 1. A method for execution by a computing device of a dispersed storage network (DSN), the method comprises: executing a rebuild function to produce a rebuilt encoded data slice for storage in a targeted storage unit of the DSN; when the targeted storage unit is currently unavailable: storing the rebuilt encoded data slice in local memory of the computing device;recording storage of the rebuilt encoded data slice in the local memory; andrecording that the targeted storage unit is currently unavailable; and when the targeted storage unit is currently available: sending the rebuilt encoded data slice to the targeted storage unit; andrecording storage of the rebuilt encoded data slice by the targeted storage unit. | ||
