HBA Probs /boot on SD-Card with ZFS?

[cpzengel]

Hi Guys,

due a couple of HBA Problems I´d like to only put the Image and Grub to a SD-Card and keep it updated.

So instead of the first Partition it should boot the Image from the SD-Card

Is there any way to do this?
I did not get it working here.

Btw. The Rescue boot does not find any rpool and does not light up the HDDs, even the installation on this HBA worked fine.

Sure, if your hardware can boot of SD. If you have UEFI, there is also an example on the wiki:

If you use "legacy boot", there are tons of examples for Debian out there, e.g. https://wiki.debian.org/BootUsbWithGrubRescue
