Description of problem:
=======================
After rebalance is triggered on the volume, on few files I am seeing below warnings in rebalance logs,

[2018-02-20 05:35:39.439245] W [MSGID: 109023] [dht-rebalance.c:2036:dht_migrate_file] 0-distrepx3-dht: Migrate file failed:/1/linux-4.6.4/Documentation/devicetree/bindings/mfd/arizona.txt: failed to get xattr from distrepx3-replicate-2 [No data available]

I am seeing may such warnings in the rebalance logs and logs will get flooded with these warnings if we have large dataset.


How reproducible:
1/1

Steps to Reproduce:
===================
1) Create a x3 volume and start it.
2) FUSE mount it on multiple clients.
3) Run linux kernel untar from two clients .
4) While IO is in-progress, add bricks to the volume and start rebalance without force.

Actual results:
===============
Seeing, "Migrate file failed: <filepath>: failed to get xattr [No data available]" warnings in rebalance logs

Expected results:
================
Should not see the above mentioned warnings
