Yes, I could see the volume in the pool. I was able to examine it with qemu-img tool, and it showed both the intended extents and the actual on-disk size.
But inside the vm, the drive did not appear as the intended size, but rather the on-disk size. Anaconda would not partition the drive because it was too small. I ran fdisk -l /dev/sda inside the anaconda shell and it was very small.
