As mentioned here, ZFSBootMenu prior version 2.2.1 is not able to boot a zpool once updated.
It took me some time and a few tries to understand that the solution is incredible simple.
Based on the official documentation, all you have to do is to:
- Boot from a live iso like archzfs.iso
- Mount your EFI-Partition
curl -LJO https://get.zfsbootmenu.org/efi
cp zfsbootmenu*.EFI /efi/EFI/ZBM/vmlinuz.EFI
- Umount your EFI-Partition
I've updated the archzfs iso build script to automatically create a iso file with the latest ZFSBootMenu pre-shipped.
