最近我对我的 Ubuntu 进行了更新，它一开始似乎可以工作，但重启后显示：
kernell ofset relocation range kernel panic not syncing: VFS
我尝试使用 Grub 中的其他旧内核，但它们似乎都存在同样的问题
我已更新的 Ubuntu 是在 Bios 中安装在名为“MainRaid”的 Intel Rapid raid 上的（Raid 在发布期间报告为工作正常）它还启动了 Grub 并尝试加载内核（未成功）
我已经下载了 ubuntu 22 并制作了一个可启动棒，我尝试通过从我的 raid 复制数据来保存数据（通过使用实时版本），问题是我无法让 raid 再次被发现
首先我跑sudo fdisk -l
我可以看到三张光盘，两张是物理的（突袭成员），一张是虚拟的，这是我的输出：

GPT PMBR size mismatch (500113671 != 500118191) will be corrected by write.
The backup GPT table is not on the end of the device.

首先我尝试恢复突袭：
root@ubuntu:~# mdadm --assemble --run /dev/test /dev/sdb /dev/sda
mdadm: /dev/sdb is busy - skipping
mdadm: /dev/sda is busy - skipping
我也尝试这样：
root@ubuntu:~# mdadm --assemble --run /dev/sdb /dev/sda
mdadm: device /dev/sdb exists but is not an md array.
然后我试图阻止突袭
root@ubuntu:~# sudo mdadm --stop /dev/mapper/isw_dcffbfjabb_MainRaid
mdadm: /dev/mapper/isw_dcffbfjabb_MainRaid does not appear to be an md device
然后尝试停止光盘：
root@ubuntu:~# sudo mdadm --stop /dev/sda
mdadm: /dev/sda does not appear to be an md device
然后我尝试安装 raid 和/或单个磁盘
root@ubuntu:~# sudo mkdir /media/dysk1
root@ubuntu:~# sudo mount /dev/sdb /media/dysk1
mount: /media/dysk1: unknown filesystem type 'isw_raid_member'.
root@ubuntu:~# sudo mount /dev/mapper/isw_dcffbfjabb_MainRaid /media/dysk1
mount: /media/dysk1: wrong fs type, bad option, bad superblock on /dev/mapper/isw_dcffbfjabb_MainRaid, missing codepage or helper program, or other error.
root@ubuntu:~# sudo mount /dev/mapper/isw_dcffbfjabb_MainRaid-part3 /media/dysk1
mount: /media/dysk1: special device /dev/mapper/isw_dcffbfjabb_MainRaid-part3 does not exist.
我也这样做了root@ubuntu:~# sudo mdadm --assemble --scan，但没有输出
我也这么做了
root@ubuntu:~# vgdisplay -v
No volume groups found.
root@ubuntu:~# cat /proc/mdstat
Personalities :
unused devices: <none>
另外，为了参考，我粘贴了root@ubuntu:~# mdadm --examine /dev/sd*

我的磁盘上有非常重要的数据，我决心以某种方式访问它，有人知道发生了什么事吗？
