For anyone looking to build an iSCSI target on their new Helios64, I can confirm that it's working correctly under the test builds for Armbian 20.11.

Thanks to @aprayoga for his comment on the pull request, the kernels modules related to LinuxIO have been added to all boards in the Armbian project.

 

Out of curiosity what is the (web?) interface in your screenshot.

It's called cockpit - it listens on port 9090

You can install it with:

sudo apt -y install cockpit cockpit-networkmanager cockpit-packagekit cockpit-storaged

 

Do you know of a good guide for getting iSCSI working with ZFS? Or just a guide for iSCSI? I took a brief look around but everything so far is over my head.

@wurmfood

This guide might be a good starting point for you - just replace the lvm2 with your ZFS implementation.

I prefer to use targetcli tool to manage my targets, but the concepts are the same.

@wurmfood

You should be able to use a ZVOL or create a file on the dataset that represent the target (blockio and fileio) respectively.

I was able to get it working and played with it. I didn't realize I had to create a ZVOL to make it work, and it introduced some interesting problems. I'm not sure I'll stick with it, but I like the idea as a backup solution for the local Windows machines.

What problems did you get?

I found a post from 3 year ago - thou it was made for CentOS it contains a basic setup for ZFS and iSCSI, these steps work on Armbian as well.

zfs create -o volblocksize=32k -V 10G tslpool/iscsi1
zfs set sync=disabled tslpool/iscsi1
targetcli
block/ create name=block_backend dev=/dev/zvol/tslpool/iscsi1

# create acl with the initiator (client) name here, not the one you just created
