[help]pve reboot error

The PVE 7.1 error after reboot is shown in the image
What is the situation, please. How to fix

Hi,
can it be that your /etc/fstab contains a reference to /dev/sdd1? Those device links are not stable across reboots, i.e. you might end up with a different naming of the disks. You can use ls -l /dev/disk/by-uuid to get the UUIDs of the filesystems and then use UUID=XYZ-XYZ instead of /dev/sdd1 as the reference in the fstab file.

P.S.: Proxmox VE 7.1 is very old, after fixing the issue at hand, please consider upgrading to at least the latest 7.4:

Because there is no upgrade in the production environment, I'm afraid

Because I haven't touched any settings, there is any possibility that it will be fixed, it is because you can't enter the system after the power is off

You can use a live-CD to attempt to fix up configuration of the system: E.g. follow the steps here https://pve.proxmox.com/wiki/Recover_From_Grub_Failure including the chroot command, but no need the execute the grub commands!

Now the situation is bootable, but there will be a situation like the one shown in the figure. I need to enter a password and the system doesn't boot, I used lsblk to check and found that pve-data is missing

Does it show with lvs? You can check your boot log for any mentions of it, but are you sure it was not removed at some point (you might also want to check the shell history)?
