This application discloses a method, apparatus, and medium for handling abnormal RAID member disks, relating to the field of disk array storage. In order to reduce the experimentation of hot spare disks, this application provides a method to reserve a portion of storage space on the RAID member disks to store data sent by the host to the abnormal RAID member disks in the event of an abnormal RAID member disk. During the process of repairing the abnormal RAID member disks, the I / O commands received by the RAID card are directly cached in the hard drives of other normal member disks. After the RAID card successfully repairs the abnormal member disks, the RAID card can restore the data stored in the reserved storage space to the member disks that were abnormal before the RAID, avoiding data inconsistency problems caused by the member disks being unable to receive I / O commands. If the member disks can be successfully repaired, there is no need to start the hot spare disk.

This utility model relates to the field of rail vehicles, and discloses a waste discharge device and a rail vehicle for urban rail vehicles. The device includes a waste discharge shell and a waste discharge mounting base. The waste discharge mounting base is located at the train's exhaust vent, and the waste discharge shell is located at the waste discharge mounting base to accommodate the train's exhaust vent. The waste discharge shell is a column with an upper opening and a lower opening, and a ventilation baffle is provided between the upper opening of the waste discharge shell and the train's exhaust vent. This application standardizes the waste discharge interface of urban rail vehicles by setting a waste discharge mounting base at the train's exhaust vent. Compared to the existing method of designing a separate waste discharge device for each train's exhaust vent, this method only requires improvement of the waste discharge shell, without considering the influence of the train's exhaust vent location and interface size, thus reducing the workload of replacing waste discharge devices. The ventilation baffle between the upper opening of the waste discharge shell and the train's exhaust vent divides the interior of the waste discharge shell into multiple cavities, reducing noise and improving the passenger experience.
