实际驱动器 meaning in English

real drive

The second choice would be closer to what would happen in the event of a real drive failure , while the first would simulate something like a failed disk controller or bad cable situation - where one of your mirror drives was temporarily unavailable , causing dev md0 to run in degraded mode , and requiring one of the partitions to be added back to the volume after the problem was remedied
尽管第一种方案也模拟了一些事件，如磁盘控制器故障或电缆故障，但第二种方案与对实际驱动器故障的处理更加类似在第一种情况下，只是某个镜像驱动器暂时不可用， / dev / md0以降级模式运行，在问题得到修正以后，需要再次将一个分区添加到卷中。
