via the UI storage is showing the default disk is not ready and that the UUID does not match. when I select add disk it shows me nvme0n1 but then a format option (which I am not prepared to do unless I know it is not truly using that disk.

I have never really been a *nix engineer but through years of supporting infrastructure equipment based on *nix and having to get in to the guts of things (EMC, vmware, f5) I have picked up on a few things.
How do I determine whether nvme0n1 is not sda?
sorry, meant this to be a reply for proper threading:
lspci is not installable and the harvester RO filesystem and the list PCI devices in the UI is experimental and enabled but I can't see anything via that.
/proc/bus/pci/devices is a bit too long for the combination of session, screen size, etc. I am using
I suspect a number of problems I have been having is due to disk pressure on that one little nvme guy. super fast but I suppose that through all the layers of virtualization going on, there is some latency there, especially if any swap is happening in the kvm VMs.
took a chance and force formatted it.
The UI says, "The disk has already been force-formatted. Current file system is ext4, You can format it manually."
now I am navigating this, https://longhorn.io/docs/1.1.1/volumes-and-nodes/multidisk/
to see how I can use that nvme.
You would think this would be easier in the front end UI. We're getting there. Soon this will be a fully packaged solution and partner integration to rival the likes of vmware!
actually longhorn on harvester 1.1 is 1.3.2... checking those docs
still says, "Add a Disk
