[Gluster-users] files on gluster brick that have '---------T' designation.

I have a working but unbalanced gluster config where one brick has about 2X
the usage of the 3 others.  I started a remove-brick to force a resolution
of this problem (Thanks to JD for the help!), but it's going very slowly,
about 2.2MB/s over DDR IPoIB or ~2.3 files/s.  In investigating the
problem, I may have found a partial explanation - I have found 100s of
thousands (maybe millions) of zero-length files existing on the problem
brick that do not exist on the client view that have the designation
'---------T'
via 'ls -l'

ie:

/bducgl/alamng/Research/Yuki/newF20/runF20_2513/data:
total 0
---------T 2 root root 0 2012-08-04 11:23 backward_sm1003
---------T 2 root root 0 2012-08-04 11:23 backward_sm1007
---------T 2 root root 0 2012-08-04 11:23 backward_sm1029

I suspect that these are the ones that are responsible for the enormous
expansion of the storage space on this brick and the very slow speed of
 the 'remove-brick' operation.

Does this sound possible?  Can I delete these files on the brick to resolve
the imbalance?  If not, is there a way to process them in some better way
to rationalize the imbalance?
