You should expect that checking a live filesystem will produce errors,
actually.  So don't worry about that.  The filesystem is not quiesced,
and it's not consistent.  That is to be expected, and it's why you see
the different behavior w/ forcefsck vs. e2fsck -n on the live fs.

As for the spurious ENOSPC, I'm not certain.  Do you still get the error?
