TL;DR: Getting error trying to move Local-LVM to iSCSI.
Getting error

create full clone of drive scsi0 (local-lvm:vm-102-disk-1)
TASK ERROR: storage migration failed: can't allocate space in iscsi storage

Short Story Long:
New to Proxmox, but have been expanding my knowledge of it thanks to vmware's expensive ecosystem.
In my test environment, I have a fairly simple setup: 2 Nodes, connected via iSCSI to TrueNAS Server (10G connection)

No issues creating traditional VMs, but having all kinds of fits with HomeAssistant OS.
Tried numerous of times to get it to install on the iSCSI Share with no success..

Finally installed it locally on one of the hosts, and trying to move storage from the Local Node to my NAS where it have the inherited resilience

It seems like you are trying to move data to "raw" iSCSI storage. You can't do this - there needs to be an LVM layer on top of the iSCSI.

You are correct, this is Raw storage. I will be following the link you sent and tinker with this. Once setup, all Nodes access this for HA?
