无法挂载'/ dev / sda'

我的服务器在RAID 1中有两个2 TB的硬盘驱动器。 我无法挂载/dev/sda

parted -l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: Number Start End Size File system Name Flags 1 20.5kB 1049kB 1029kB primary bios_grub 2 2097kB 1987GB 1987GB primary 3 1987GB 1992GB 5242MB ext4 primary 4 1992GB 2000GB 8388MB linux-swap(v1) primary Error: /dev/sdb: unrecognised disk label Model: ATA HGST HUS724020AL (scsi) Disk /dev/sdb: 2000GB Sector size (logical/physical): 512B/512B Partition Table: unknown Disk Flags: 

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 (eg /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?

不要尝试直接安装设备! 你需要挂载它的一个分区。

例如,你这样做是错误的

 mount /dev/sda /mnt 

你应该做的是:

 mount /dev/sda3 /mnt 

系统需要包含在分区中的元数据知道如何处理它。 如果您直接安装设备,这些元数据丢失,安装将失败。
