Your df screenshot seems to indicate you don't have any mounted storage.

Attach Diagnostics ZIP to your NEXT post in this thread.

And your diagnostics confirms this. In fact, you have only 1 nvme and you haven't assigned it. So, there is no storage for user shares to exist on.

Unraid v7 allows you to create pools without having an array. Create a pool for your nvme, and let Unraid format it so Unraid will have a place to store libvirt.img.

Ah, I see... I thought the USB installation would have anything it needed to have a running system. I'll give this a shot. Thanks!

You Do have a running system - just one with no storage 😊

I've spent some time trying to use the NVMe in the system, which I had been using for other things, including installing another OS for a different PoC, and unraid is refusing to use it, saying it's bad. I tried to post a comment with a snip and a file, but it wasn't posting. Trying a reply with only text now.

Flash drive issues:

You can try reformatting it first, but if the issues persist, you should replace it.

That's the flash drive that I'm booting from. I took it out by mistake. The drive with the problem is nvme0:


(I figured out why it wasn't posting before... it was the myriad of dots)

Phase 1 - find and verify superblock...
bad primary superblock - bad magic number !!!

attempting to find secondary superblock...
........could not find valid secondary superblock
Exiting now.

Did you let Unraid format it?

Reboot to clear the logs,reformat the pool, and post new diags with the array still started.

Will do, thank you

I must have done something wrong. I replaced the disk, and the new disk was working fine. Then I put back the original disk, and it seems to be working fine as well. Formatted as both btrfs and xfs. Thank you to everyone who responded.
