Can you replicate the problem using resize2fs from e2fsprogs version
1.41.0?  Resize2fs has supported online resize for quite sometime, and
I'm not sure the ext2online tool is being actively maintained at this
point.

Out of curiosity, why are you using a 1k blocksize?  Does Virtuozzo
require it?  Especially for a filesystem as big what you are
apparently using, there will be some significant performance downsides
with using a 1k blocksize.  And the -i 1024; are you storing huge
numbers of small files?
