Rebuilding a storage array |
| 摘要 |
The present invention discloses a method and apparatus for rebuilding a storage array. The method comprises: replacing, in response to a failing storage device occurs in the storage array, the failing storage device with a first spare storage device; performing component rebuild by using other storage devices in the storage array than the first spare storage device, so as to restore within the first spare storage device data in the failing storage device; performing, in parallel with the component rebuild, smart rebuild by using a second spare storage device, so as to copy data in the failing storage device to the second spare storage device; replacing the first spare storage device with the second spare storage device in the storage array upon completion of the smart rebuild. |

1. A method for rebuilding a storage array, comprising:
replacing, in response to a failing storage device occurs in the storage array, the failing storage device with a first spare storage device; performing component rebuild by using other storage devices in the storage array than the first spare storage device, so as to restore within the first spare storage device data in the failing storage device; performing, in parallel with the component rebuild, smart rebuild by using a second spare storage device outside of the storage array, so as to copy data in the failing storage device to the second spare storage device; and replacing, in response to completion of the smart rebuild, the first spare storage device with the second spare storage device in the storage array. |
