Probably? Is it likely that you have any empty files? I don't know.

Very good question. I don't know. The xattrs tell a strange story that I 
haven't seen before. One legit file shows sr_vol01-client-32 and 33. 
This would be normal, assuming the filename hash would put it on that 
replica pair (we can't tell since the rebalance has changed the hash 
map). Another file shows sr_vol01-client-32, 33, 34, and 35 with pending 
updates scheduled for 35. I have no idea which brick this is (see 
"gluster volume info" and map the digits (35) with the bricks offset by 
1 (client-35 is brick 36). That last one is on 40,41.

I don't know how these files all got on different replica sets. My 
speculations include hostname changes, long-running net-split conditions 
with different dht maps (failed rebalances), moved bricks, load 
balancers between client and server, mercury in retrograde (lol)...

Identify which replica is correct by using the little python script at 
http://joejulian.name/blog/dht-misses-are-expensive/ to get the hash of 
the filename. Examine the dht map to see which replica pair *should* 
have that hash and remove the others (and their hardlink in .glusterfs). 
There is no 1-liner that's going to do this. I would probably script the 
logic in python, have it print out what it was going to do, check that 
for sanity and, if sane, execute it.

But mostly figure out how Bricks 32 and/or 33 can become 34 and/or 35 
and/or 40 and/or 41. That's the root of the whole problem.
