And anyway - I thought the maximum size for ext3 was 8TB ?

I know that there are patches to bring it up to 16TB, but does anybody trust these and use them for production systems?

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.
