resize4fs indicates that you are on a Red Hat Enterprise Linux 5 system,
so this may go better through your Red Hat support contacts.

I have some open bugs similar to

Bug 654093 - [6.0]The resize2fs command fails to run on a 16TiB filesystem.

which was fixed in RHEL6.1.

Well, the issue is that the device itself is more than 16T, and the e2fsprogs
tools won't even touch it; e2fsprogs has never released more than 32-bit
support.  I would recommend resizing your device to something small enough
for e2fsprogs to handle.

Thanks,
