Capabilities of NVMe-oF so far?

Started playing around with NVMe-oF last night and got a successful connection to TrueNAS.

I'm wondering what the current capabilities/limitations are.

As far as I can tell you can't cluster the disk which is what I was primarily interested in.

I was able to connect the same NQN endpoint to two servers but the WSFC cluster wouldn't detect it as a cluster available disk.

Also the disks seems to disappear on every reboot and has to be set up again, so is there no auto-mount yet?

I understand this is early preview so I don't have many expectations, just would like some clarity.

Thank you.
