Can't restart pve after shutdown

[shira]

Hi
Just now I shut down the pve, and when I turn it on again, it prompts:

error: attempt to read or write outside of disk 'hd0'

I looked at this article and tried to fix it as it says
https://askubuntu.com/questions/397...pt-to-read-or-write-outside-of-disk-hd0-error

grub rescue > set root=(lvm/pve-root)
grub rescue > set prefix=(lvm/pve-root)/boot/grub
grub rescue > insmod normal
grub rescue > normal

But still can't start

I tried to restore as described in this article
https://pve.proxmox.com/wiki/Recover_From_Grub_Failure

But I can't mount /dev/sda1
This post's method doesn't seem to support gpt partitions
i can't go on

Now I don't know what to do
can someone give me some advice?

That Wiki page seems stale. sda1 is probably the bios boot partition (<1MB). I don't think that particular step is necessary. Can you chroot when you skip mounting /dev/sda1?
