so this will create a fresh "root_fs" with new size.
and, I want to resize "root_fs_old"

Can I do it in this way? (without using ext2reszie)
$ losetup /dev/loop0 /path/to/root_fs; losetup /dev/loop1 /path/to/root_fs_old 
$ mke2fs /dev/loop0
$ mkdir /mnt/new /mnt/old
$ mount /dev/loop0 /mnt/new; mount /devloop1 /mnt/old
$ cp /mnt/old/* /mnt/new
$ umount /mnt/new; umount /mnt/old

So, if using ext2resize, how can I just resize the "root_fs_old" with retaining
all the data on it, and all the existing ext2 properties, like block_size ?

I am still not very sure...Sorry for the newbie question...

Thanks again!
