A bit of googling, and I see something called overlayFS can be used... but I know nothing about that, or how dangerous it is. Anyone got a pointed to something more than the minimal how to configure docker to use it?
You could follow CentOS Atomic SIG https://wiki.centos.org/SpecialInterestGroup/Atomic http://www.projectatomic.io/download/
and/or read here and adapt in case for your storage needs: http://www.projectatomic.io/docs/docker-storage-recommendation/

Interesting, but it doesn't help me: I can't rebuild the server, it's in use, and I yum installed docker from the std. repos. What I see from the links tells me how to switch storage, not how to manually configure overlay2 storage, and whether I can do as I said, and point it to an NFS-mounted location.
I just found some RH documentation for C 7 on overlayfs, and I see it says that NFS is only usable for the the docker graphs.... So, I just found, on the two systems I'm working with it on, an unused drive. Does anyone know if it is the case that I *cannot* use the partition, but need to make an LVM on it, for docker to use it?
