I've seen that before, only for something to choke at 1-2+TiB
(1.1-2.2+TB).  That's why I always recommend, as a general
rule, never to create filesystems bigger than 1TiB (1.1TB). 
There's just too many variables that can go wrong.

As much as there have been increases to support 2, 4 or even
8TiB with Ext3 and ReiserFS, I don't trust them to be
universally compatible across various distros and kernels.

About the only kernel/filesystem combination I've ever had
bliss with were the official SGI XFS releases for kernel 2.4.
 Allegedly late SuSE Linux Enterprise Server (SLES) 9 updates
now has good support for XFS, but I've also seen people
openly complain about things not working.

But you formatted a _new_ filesystem.  If you decided to do
that, and were running CentOS, you should have stuck with
Ext3.  Just because your existing data is in ReiserFS,
doesn't mean your new, large filesystem had to be ReiserFS.

And I can understand that for your _existing_
volumes/filesystems.  But for anything _new_, stick with the
distro's kernel and its filesystem support.

And I could tell you a lot about ReiserFS that would scare
you.
The reality is that if you have data you care about, you
should stick with the distro's kernel and what it supports
for all new data.

Yes, which is why multi-terabyte support is always an open
question I don't like to leave to chance.
