iSCSI target solution on Proxmox VE

[Vanderhorn]

On my Proxmox VE nodes I have almost 20TiB of ZFS storage.
I want to create an iSCSI config over a ZFS-volume on all nodes.
Then use these as storage devices on 1 VM or CT.
Not on the CEPH pool... that is SSD based, I want it for back-up.
I am looking for the best iSCSI target solution to realise this.
Can any of you help me with tips, tricks, or better: a full solution ?
Thanks in advance for any efforts made !

You could use the LIO to configure it. But this setup will add a dependency that makes maintenance or simple reboots of the nodes very difficult.

LIO is pretty "bare bone" approach.

Check out True-NAS, Freenas, etc. Those typically provide GUI-based, built-in iSCSI-capabilities.
The hint about reboot of @Alwin Antreich is correct though. Think things through. At least twice. You may paste yourself into a corner you dont like ...
