Setup: TrueNAS Scale OS running from boot drive on a server with 5 4TB SATA drives until my dual m.2 pcie adapter arrived to run OS redundantly.
Break event: I set up a Linux virtual machine on the same zpool as my truenas apps and passed through the USB slots, including the one that was running the OS (WHOOPS!). Result: Could not load web GUI.
M.2’s arrive and I reinstall OS, import pool, only to discover that I had encrypted the zpool. I checked for a stored pass phrase in all my usual spots, but appear not to have saved one anywhere.
My only hope is trying to recover the encryption key from the USB OS drive, but when I try to boot from this USB it does not successfully load to TrueNAS web GUI.
What and why? Can you rephrase this? What did you do exactly?
You mean the root dataset of the pool is encrypted and all child datasets inherit this encryption?
Can you provide the results of this command:
zfs list -r -t fs -o name,encryption,keyformat,keylocation,encroot <poolname>
One more thing...

I went to Instances and created a new vm with the linux mint iso with mostly default settings. In the disk or storage options I think I selected something incorrect. In addition, under the passthrough options I selected the USB thumb drive that was running my truenas OS. The system was nonresponsive and each boot attempt to reboot truenas failed and indicated “fatal error.”

Every time you update TrueNAS you are asked if you want to save a copy of your configuration file, optionally including your encryption keys (will be saved as a .tar). You are also asked if you want to save a copy of the encryption keys when you create an encrypted dataset (saved as a .json).
Have you double-checked if you have either of those files in your downloads folder on your PC?

First do what @neofusion said. I assumed you didn’t backup or export anything, since you said you never exported your keys, I figured you didn’t export your config either.
