Resized ext3 part 100% used

[David Jung]

Hello.
I recently used parted for the first time to reduce the size of
an ext3 partition on i386 Linux.  I booted from a CD (redhat install
CD in rescue mode) which contains parted and proceeded to
resize my ext3 partition smaller.
parted ran for a while and seemed to complete sucesfully (at least
it reported no errors or other information - just gave me the
prompt back).
At the time, I didn't think to check just how much space was
needed to accomodate the files currently in the ext3 fs.
When I rebooted my machine via that partition (it was the / fs),
it seemed to boot up fine.  Using df showed that the partition
was now the 28GB reduced size as expected, but it was 0% available
(100% used!).  Only then did I realise I may have asked it to
resize too small!
I've run an fsck.ext3 -fv /dev/hda2 over the partition and
it didn't complain.  The system seems to work OK in the short
time I've had it up.
I just wanted to ask if parted would have checked or complained
if the fs block to be moved didn't actually fit in the reduced
size.
The fact that is it 100% full makes me nervous, but perhaps I
just got lucky and happened to have just enough space.
I haven't written any fs to the now extra space after it yet.

Anyways, if it lost some data I'll just wipe it and do a fresh
install, but I'd rather avoid that if it actually worked OK.

Thanks for parted.  I'm surprised I didn't know about it before
(have used PartitionMagic in the past)

Cheers,
