I think I just figured this out for myself. My new master backend had a 
storage group set which wasn't mounted. I have myth reserve 50GB of my 
1TB partition to avoid fragmentation (I copy the keepers to my windows 
machine for burning, and I hate to see under 5MB/s transfer rate) but 
that root partition was only 12GB, so it could never free up 50GB

I'm posting this so other people don't make the same mistake.
