EXT4 won't support file systems >16TB at all with 4k blocks, and depending on OS and tool version, the tools may not support a block size >4k.  Anaconda (the RHEL/CentOS installer) won't support >8GB during install.

Given those limitations, I consider EXT4 being limited to 16TB.  Your evaluation may vary, of course.
