This thread is getting real thick with incorrect guesses and assumptions.

ext3 is just as able to online (while mounted) resize as xfs (man resize2fs).

Regarding the partition table updating. partprobe can be used and works even 
with a mounted root filesystem on the drive as: "partprobe /dev/sda".

If the problem is below this, the block device not having been updated with 
the new size, then you maybe have to reboot or perhaps some kind of scsi 
rescan will be needed.

When "fdisk -l" finally does report all ok then you only have the upper layers 
left (lvm, fs, ..) but I think that's not the question being asked here.
