What error(s) are you getting?  Not all messages from e2fsck are
errors, you know.  Some are informative messages, such as:

	Backing up journal inode block information

Resize2fs will take advantage of the on-line resizing inode to do
off-line resizes faster and more safely.  It should work with or
without, it, though.  It should work fine; send the error messages if
you'd like me to give you an opinion about them.
