That kernel seems to be a bit old. Better upgrade first.
I did some resizes in that size range. Although just adding 50-200GB
not doubling the size in one go. But I see no reason it should
fail. Growing the fs was always quick (a minute or two) and
painless. Maybe because I have used -Tlargefile4 for mke2fs so the
amount of inodes is drastically reduced.

So was that what you were missing or did some other error occur?
I tried to resize an fs without resize_inode and it just plain told me
and abrted.
