Need help with Proxmox 6.2-12 boot grub rescue mode error

[pveuser2020]

Hi
I have rebooted this proxmox server running 6.2-12

It has gone into grub rescue mode

It reports "error: no such device: 5d901143c9e6692e"
error: unknown filesystem
entering rescue mode

It has X4 3TB drives - hardware is fully operational, no errors.

Any ideas and how I can boot into OS/proxmox ?

Thanks,

have you tried to boot from old kernel?

In such a case investigate the current boot device (whether boot directory can be read), this can be done in grub rescue mode itself (see https://www.gnu.org/software/grub/m...Command_002dline-and-menu-entry-commands.html ) or by booting with a (preferably Linux) live media.
