Hey all,

I just installed a TrueNAS X20 in our datacenter. We are setting it up to be iSCSI storage for a new HyperV cluster (two servers running WS2022 Datacenter).

I have created an iSCSI share on the TrueNAS and connected it to both servers through the M$ iSCSI Initiator. While the storage space seems connected, if I look in Event Viewer, under the system logs, I am seeing event ID 20, followed by event ID 34, over and over and over again literally every second and multiple times per second. This is happening on both servers.

I've been researching, and tried all the low hanging fruit fixes I can find on Google (changing the iSCSI timeout, verify the network interfaces configuration, jumbo frames, etc.) but the issue persists.

Here are some screenshots of what I'm seeing.

Have any of you run into this before? Can you guys help me out here?

I should also say I'm really not super familiar with Hyper-V. I'm a VMWare/ESXi guy.
