Abstract: A computer-implemented method for dropped write error detection is proposed. In the method, a read request for a stride stored in an array of storage drives is received. The stride includes segments of a data and a first parity associated with the data spreading across the storage drives in the array of the storage drives. In response to the read request being a predefined sequential read request and a state of the stride being a first state, a parity check is performed on the stride. The first state indicates that no parity check has been performed after the data is written into the array of storage drives. The state of the stride is changed to a second state, and the second state is different with the first state.

Abstract: Solutions for processing a redundant array of storage drives receiving a rebuilding request of a redundant array of storage drives. The redundant array has a first storage drive to be replaced. In response to no spare storage drive being available to logically replace the first storage drive, a second storage drive is identified, which is a source storage drive of a disk balance process being performed. A rebuilding of the redundant array is initiated by reconstructing data of the first storage drive on the second storage drive during the disk balance process.

Abstract: A forwarding path selection method and device are disclosed. If a data packet to be sent to a target device is a start packet of a flowlet in which the data packet is located, a sender device selects a low-load path from a plurality of paths to forward the data packet, and sets a forwarding decision of a flow in which the data packet is located to the selected path, where load of each path is load of traffic received by a corresponding intermediate device from the sender device or load of traffic sent by a corresponding intermediate device to the target device, whichever is higher. Flowlet-based load balancing can be implemented only by providing related functions on one type of device.
