[PVE-User] ZFS Node failing to boot

BTW, the instructions I found on the proxmox forums:

    use the Proxmox VE ISO (or USB) and start the installation in debug

    on the first stop, press CTRL-D to continue and the installer
    switches to graphic mode - not abort the installation, as you do not
    want to format your server!

    the "abort" will give you a shell and access to the zfs root file system

     > zpool import -a

Do not work for me as the keyboard does not work when booting in debug mode!
