--- Comment #10 from Alex <alex at webedge.ca> ---
The remaining files on the brick after a remove-brick seem to be due to the
fact that the brick will continue to accept new files created in the cluster
during the removal process.. any new files that were hashed onto that brick
during the removal process stand to be orphaned after the process has
completed.

see:

https://gist.github.com/mandb/93369097139c6cc3ff98

Expected behavior would be that while a brick is in remove-brick state, new
file creation requests would be relayed to another brick.

The issue is likely complicated by a few scenarios:

a) Clients still see the brick's space as part of the volume capacity...

b) Files that are STILL on the brick need to remain write-available, and those
files could be grown, so the capacity in a) has to reflect this available write
space.

I will test with 3.6.2 and see if the behavior has changed.
