RAID10：错误的 fs 类型、错误的选项、错误的超级块

我正在尝试通过在一个现有阵列和一个新的 RAID1 阵列中定义 RAID0 来设置 RAID10 阵列。

输出/proc/mdstat看起来不错：

Personalities : [raid1] [raid0] [linear] [multipath] [raid6] [raid5] [raid4] [raid10]
md125 : active raid0 md126[1] md127[0]
      7813505024 blocks super 1.2 512k chunks

md126 : active (auto-read-only) raid1 sde1[0] sdd1[1]
      3906884608 blocks super 1.2 [2/2] [UU]
        resync=PENDING
      bitmap: 30/30 pages [120KB], 65536KB chunk

md127 : active (auto-read-only) raid1 sdb1[0] sdc1[1]
      3906884608 blocks super 1.2 [2/2] [UU]
        resync=PENDING
      bitmap: 29/30 pages [116KB], 65536KB chunk

unused devices: <none>

但是当我尝试挂载时/dev/md125，出现了可怕的错误：

user@i7-harvester:~sudo mount /dev/md125 /mnt/plex
mount: /mnt/plex: wrong fs type, bad option, bad superblock on /dev/md125, missing codepage or helper program, or other error.

我还添加了来自的输出fdisk -l，它确实列出了 /dev/md125 阵列上的一组分区，但我不确定它们是如何到达那里的或者这可能意味着什么：

user@i7-harvester:~$ sudo fdisk -l /dev/md*

答案1

为了后代的缘故。我没能扩大 RAID10 配置，所以我完全格式化了所有四个磁盘，并进行了复杂的 RAID10 设置。
