Max size of filesystem for kickstart?

I am attempting to kickstart a RHEL7 VM host (on vmware 6.0) with a 10TB sda. I can reduce the size to 1.9TB and it kickstarts just fine.

Is there a CAP somewhere that limits the size of a kickstart sda for a RHEL7 host? Is there a way to get around this that doesn't involve just growing the size after the system is kickstarted?
