Iscsi related error "REPORTING OPTIONS 3 not supported" after upgrade from CORE to SCALE

TrueNAS General

I recently migrated from CORE to SCALE on my TrueNas NAS hardware.

I have two iscsi shares, that are used as passthrough drives in Proxmox to two VMs (a nextcloud VM and a proxmox backup service VM) to provide storage.

Everything seems good for the most part, and everything seems to be working. The only issue is that there is a flood of these errors in the virtual console:

Jun 18 06:48:35 storage kernel: [4585]: scst: ***ERROR***: REPORT SUPPORTED OPERATION CODES: REPORTING OPTIONS 3 not supported (dev pbsvolume, initiator iqn.1993-08.org.debian:01:d4945ff9dd15#192.168.20.X)

These errors started after migration to SCALE. I did not receive these errors in TrueNAS CORE. I would like to address these errors and don’t know where to begin. Any assistance would be greatly appreciated.

So after a lot of trying different things, the thing that finally got the error messages to stop was to create a whole new extent/target/initiators using the wizard, and then connecting it to a VM. I did also select “Modern OS” as the compatibility option for the extent instead of VMware, but I don’t know that made a difference.
