Thanks in advance. :)

TrueNAS-SCALE-23.10.1.1

Proxmox 8.1.4 with 2 node cluster in a home/smb environment.

Main network is 1Gbe, Storage Network is 10Gbe.

Attempting to set up storage per many articles, but this one in particular by Surfrock66. All configs followed (SSH, etc)

Its working....sort of? After deleting and recreating the storage 100 times with multiple reboots of both systems, I can migrate the disk of a PVE VM from local storage to the TNS target, then i can migrate it back from the target to local. BUT. the push from the local to the target gives me disconnects in the process:

qemu-img: iSCSI: NOP timeout. Reconnecting...
qemu-img: iSCSI CheckCondition: SENSE KEY:UNIT_ATTENTION(6) ASCQ:BUS_RESET(0x2900)

It DOES reconnect on its own and complete.

Target to local is much faster, but I did see this in the log at the top:

qemu-img: iSCSI GET_LBA_STATUS failed at lba 0: SENSE KEY:ILLEGAL_REQUEST(5) ASCQ:INVALID_FIELD_IN_CDB(0x2400)

Again, it completes, with no interruptions in the process except that at the beginning.

Not new to PVE but new to shared storage, and know enough linux to be dangerous XD. What more info can I provide to get some community assistance?
