16TB ext3 support was included as a technology preview in RHEL5 and fully 
supported in 5.1.  I've got a couple of >8TB ext3 FSes.  Why ext3? 
Because nothing else is as well supported by the vendor on RHEL/CentOS. 
For primary file servers, I don't want to muck about with add-on kernel 
modules, "plus" kernels, or anything else of that sort.  I want to run as 
close to stock as possible.  And on anything RHEL derived, that means 
ext3.
