無法掛載“/dev/sda”

  • December 11, 2014

**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

root@rescue:~# parted -l

Disk /dev/sda: 2000GB
Sector size (logical/physical): 512B/512B

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
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] [faulty]
unused devices: <none>

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。
