Not according to the ext3 FAQ (see link in thread) and some extensive
testing I did over the weekend.
Ext2 is 16TB. Ext3 is only 4TB.

I've seen you mention that 1TB limit. Could you please post some
references to it?
I'm now familiar with limits at 2TB (gpt), 4TB (ext3), 16TB (ext2) but
you're the only person talking about a 1TB barrier.

I'd like to hear about that.
