Fresh install ZFS (RAID1), can't boot after reboot


Mar 8, 2019

i've just installing Proxomox 5.3 on HP core i5 3470 16 Go , 2 x HDD 500 Go
Choosing ZFS RAID1 for this two drive, in order to have RAID 1 (i hope that ZFS , in RAID1 mode will not eat all my 16 Go memory ...).
Installing is ok, but when the computer reboot .... tadadadddadaa : PXE boot only !

Bios setup is legacy , when installing with one drive /dev/sda ... everything is ok.

Do you have an idea ?

(i'm newb with zfs, but skilled with mdadm ... and is working perfectly with pve 5.3 , from a debian vanilla install)
Trying to install on HP pro 3500 with uefi disabled , it seems proxmox install can't install grub on disk !
partition scheme ... with ZFS RADI1 install :
1MB biosgrub
539 MB B
499.6GB zfs ...

on sda and sdb but cant' boot ...
Sorry for bumping an old thread but were you able to figure this out? I’m running into this issue with Proxmox 7
