degraded mode中文
簡化工作方式
例句與用法
- Here , you can see that my dev md0 volume is running in degraded mode
您可以看出/ dev / md0卷正在以降級模式運行。 - Our raid - 1 volume would still be running in degraded mode at this point
此時我們的raid - 1卷仍將以降級模式運行。 - Our raid - 1 volume would be running in degraded mode , meaning that our volume is still available but without any redundancy
我們的raid - 1卷將以降級模式運行,即該卷仍然可用,但是不再有任何冗余。 - In this section , i ll walk you through the process of simulating a disk failure , and then bringing your raid volume back out of degraded mode
在這一節,我將帶您體驗模擬磁盤故障的整個過程,隨后使您的raid卷退出降級模式。 - 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
盡管第一種方案也模擬了一些事件,如磁盤控制器故障或電纜故障,但第二種方案與對實際驅動器故障的處理更加類似在第一種情況下,只是某個鏡像驅動器暫時不可用, / dev / md0以降級模式運行,在問題得到修正以后,需要再次將一個分區添加到卷中。
百科釋義
When a RAID array experiences the failure of one or more disks, it can enter degraded mode, a fallback mode that generally allows the continued usage of the array, but either loses the performance boosts of the RAID technique (such as a RAID-1 mirror across two disks when one of them fails; performance will fall back to that of a normal, single drive) or experiences severe performance penalties due to the necessity to reconstruct the damaged data from error correction data.
