无法挂载“/dev/sda”

我的服务器有两个 2 TB 硬盘柔软的RAID 1。我无法装载/dev/sda。

输出parted -l

root@rescue:~# parted -l
Model: ATA HGST HUS724020AL (scsi)
Disk /dev/sda: 2000GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Error: /dev/sdb: unrecognised disk label

输出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?

输出cat /proc/mdstat

root@rescue:~# cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] [faulty]
unused devices: <none>

我如何访问我的文件？

不要尝试直接安装该设备！您需要安装它的一个分区。

例如，这是错误的当你这样做时：

mount /dev/sda /mnt

你应该做的是：

mount /dev/sda3 /mnt

系统需要分区中包含的元数据才能知道如何处理它。如果你直接挂载设备，这些元数据就会丢失，挂载将彻底失败。
