For comparison, below is the output of getfattr on each brick and

That looks pretty reasonable - an approximately even split of the
DHT hash range across the three bricks, which should result in
files being evenly allocated between them. Also, you said that
there was a directory where you *didn't* see the problem? Could
you run the same command there for comparison?
From the last directory I was able to create on all 3 brick:

the client returned nothing.
