Thinpool says it's nearly 52% full but there's nothing on it!

[dmpm]

I've got my 174.39GB pve-data thinpool which has four LXCs on it (no VMs on this machine) and I also created a 500GB USB-data thinpool on a 1TB USB NVME, which has no LXCs or VMs on it, but it's showing as 51.79% used, as you can see below (278.05 GB of 536.87 GB in the GUI).

What's going on here and what can I do to clear this state so it correctly shows that the data thinpool is currently empty?

It's used by monero-data. I have no idea what that is used for though.

Oh, I thought that the monero-data and pbs LVs would be entirely separate from the data thinpool. Why would monero-data be sharing space with data but pbs isn't?

I can't really answer that. I don't know what you did or why. You can see that monero-data is a thin volume and part of the USB VG and data pool. pbs is a thick volume and not part of data. That's all I can tell you. There's little reason to quote a messgae you're directly replying to, by the way.
