Is it possible to get raw block device storage on nodes in the CI?
Right now from what I can tell the nodes come up with LVM set up and
no space free in the volume group. There is a root/home/swap LV and we
can't really reclaim any space because xfs doesn't support shrinking
the FS.

Can we have some free space left in the VG? Is there some other way to
get this to happen?
