Hi,

Proxmox VE is not a storage box, so we do not provide this kind of setups.

ZFS over iSCSI is used if you have a external storage box like FreeNas.

Debian Stretch use lio as iscsi target what should also work with IET.

Hello,

I'm trying to setup Proxmox 5.0 node as shared storage node (basically I
have a 4x10TB disks inside that server, Proxmox installed on ZFS RAID 10
filesystem). I'm willing to use this node as a host for KVM vms, and
also as a storage source for my other nodes.

The issue is that I cannot seem to setup this node as a ZFS-over-iSCSI
source for the other nodes. It looks like Debian Stretch (base system
for Proxmox 5.0) has dropped support for "iscsitarget" package that was
available in Debian Jessie - iscsitarget package provides tools for IET
(ietadm, ietd). So the problem comes when I'm trying to setup new
ZFS-over-iSCSI storage from the Datacenter GUI: there I have to choose
iSCSI Provider module - Comstar, istgt, IET.

I cannot choose Comstar because it is purely for Solaris type of OS.
I cannot choose IET because my Proxmox 5.0 host has no IET (iscsitarget)
package available.
And as a last resort, I have tried "istgt" as a provider (before that, I
installed "istgt" package inside my Proxmox 5.0 storage node).
Before doing this, I followed Proxmox wiki page and set up ssh keys for
authorization on Proxmox 5.0 storage server. This is all working good.
However, if I choose istgt as a provider, I get the following error
whenever I try to create/run new vm that's storage source is set to
ZFS-over-iSCSI volume:

TASK ERROR: create failed - No configuration found. Install istgt on
192.168.88.2 at /usr/share/perl5/PVE/Storage/LunCmd/Istgt.pm line 99.

istgt is actually installed on 192.168.88.2.

The question is how to use ZFS-over-iSCSI in this scenario?

Thanks!
