USB - would have tried PS/2 if I had one :)


If USB are your keyboard connected through a USB3 port?


All ports are USB2. I tried several different ones.


I resolved my boot problem by using the rescue ISO to boot into the 
native system (non UEFI), than doing


 * grub-install 
 * update-grub2


I don't think I'll use a ZFS  system drive in the future, its been 
endless hassles. Boot issues are a regular problem.



Thanks.

Re: [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
   mode.

   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!

Fortunately I was about to boot the system using the rescue mode from 
the Proxmox ISO, and it running fine now, but still won't boot without 
the rescue iso. But I can access the disks and they seem ok.



I presume its some sort of grub error but I have no idea how to repair 
a zfs boot drive.
