out what files are in those block groups).

The defrag
Alright! After doing:
cd /mymedia; find . -type f | while read file; do mv -v $file /dev/shm;
f2=`basename $file`; mv -v /dev/shm/$f2 $file; done
I finally moved whatever files out of the single allocation and back onto the
new RAID1 profile:

You could also try a full defragment by specifying -r on the mount point
with a small -t value to effectively cause everything to be subject
to defragmenting. If this still doesn't permit soft rebalance, then maybe
filefrag can find files that

Doing this is definitely helping,

Based on my reading of the man page, I think it's expected.
You either need -s -l or -t.
Ok, although the man page uses [ ] instead of and something
does happen if I don't add them. But if I use -t 1 wouldn't that
