I repeat (and it's getting very repetitive...)
It is *NOT* trivial to extend an ext2fs filesystem, even at the end,
by more than about 256MB. There are fundamental properties about the
location of group descriptor blocks which make this unavoidable given
the current fs layout on disk. Any significant stretching of the
filesystem requires internal reallocation of data blocks and/or inode
blocks. It is a dangerous myth that this action is simple.
