Which is why you should feel free to believe I pull everything out of my
asshole -- I've said that before, and I'll say it again.
Of course, it's often my documentation that gets referenced by other
people -- Google searches, print publications, etc... and "explains"
things. And it's _that_repeatable_, technical information year in and
year out that earns my trust. I've only been posting here 4 months. In
4 years, you might feel differently.

It's a signed 32-bit integer for number of sectors. That results in a
1.1TB (1TiB) limitation. Ext3 has them all over the freak'n place in
its codebase, although I haven't seen it on kernel 2.6.5+. In other
words, I don't like to have Ext3 data volumes over 1TB because some
systems just simply can't read them.
REAL WORLD EXAMPLE:
I previously ran into the issue where I created a 2TB Ext3 volume o a
SAN device, and select versions/kernels could not use it. But the
second I tried to mount a sub-1TB Ext3 filesystem from the same creator
on the same system, I had no issue.
I have absolutely _never_ ran into that problem with XFS -- Irix, Linux
2.4, etc...

Whatever you think it is, go on an answer for me.
I'm used to you answering for me now. ;->
