I did some googling on this recently, and I found that while ext4 
theoretically supports such large filesystems (and you can find/compile 
userspace tools to create them), the developers don't really recommend 
using it for such yet.  It's just not deemed ready for production yet.  I 
saw multiple recommendation (including from RH devs) to use XFS if you 
need filesystems that big.
