So I've screwed up... when I filled up my LVM, I added a disk to the Volume
Group and expanded the pool.
But I didn't encrypt the new drive, thinking I had LVM on LUKS. But I have
this now.

With this LVM on LUKS setup, extending the thin pool onto a new disk that was
added to the volume group... winds up leaving plain text data on the new disk.
Here's what I think my setup will have to be:
nvme0n1 (2 drives in hw RAID 0)
├─nvme0n1p1 part /boot
└─nvme0n1p2 part
└─luks (same key) crypt
├─qubes_dom0-pool00_tmeta lvm
├─qubes_dom0-pool00_tdata lvm
│ └─qubes_dom0-pool00-tpool lvm
│ ├─qubes_dom0-pool00 lvm
│ ├─qubes_dom0-root lvm /
│ └─ ... vm lvm
└─qubes_dom0-swap lvm [SWAP]
sda (2 drives in hw RAID 0)
└─sda1 part
└─luks (same key) crypt
└─qubes_dom0-pool00_tdata lvm
└─qubes_dom0-pool00-tpool lvm
├─qubes_dom0-pool00 lvm
├─qubes_dom0-root lvm /
└─ ... vm lvm
With your ykluks dracut module:

I will be a tester for this.
Thanks
