無法掛載“/dev/sda”

**我的伺服器在軟RAID 1**中有兩個 2 TB 硬碟驅動器。我不能掛載/dev/sda。

的輸出parted -l

的輸出mount /dev/sda /mnt

root@rescue:/mnt# mount /dev/sda /mnt
mount: block device /dev/sda is write-protected, mounting read-only
NTFS signature is missing.
Failed to mount '/dev/sda': Invalid argument
The device '/dev/sda' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

的輸出cat /proc/mdstat

root@rescue:~# cat /proc/mdstat

如何訪問我的文件？

不要試圖直接安裝設備！你需要掛載它的一個分區。

例如，當您這樣做時這是錯誤的：

mount /dev/sda /mnt

你應該做的是：

mount /dev/sda3 /mnt

系統需要包含在分區中的元數據來知道如何處理它。如果你直接掛載設備，這些元數據會失去，掛載會慘遭失敗。
