I don't think your configuration should cause any trouble...
I'M not sure but parted 1.6.3 is quite old maybe it was unable to detect
ext3 partition back at that time. But even yet parted doesnt handle the
journaling part of the ext3! You will have to disable it (thus putting
it back to ext2) and reenable it after the resize
Maybe you should give a try to a more recent parted too... we are now at
1.6.20
