I haven't used ext2online myself, but I believe that there are some
aspects of the filesystem that it is not able to resize, and you have
to have created your filesystem with the understanding that you might
want to grow it later.
From the mkfs.ext3 man page:
-E extended-options
...
resize=max-online-resize
Reserve enough space so that the block group
descriptor table can grow to support a filesystem
that has max-online-resize blocks.
Not a very desirable situation, but just part of the legacy that
ext2/3 brings with it.
So this time when you mkfs your new arrays, plan for growth :-)
