Abstract: In a storage system, a control device determines that at least one first storage device of X storage devices is out of service. Then, the control device selects a second storage device from the X storage device. A quantity of stripe members of a data stripe stored in the second storage device is less than a ratio of T divided by X. The control device further writes target data into the second storage device. The target data is a data unit or a check unit used to update at least one stripe member of the data stripe stored in the first storage device.
