Gluster users - Dec 2016 - GNU TAR - file changed as we read it

Hi all,

I upgraded Gluster servers and clients to 3.8.5 but still getting "file
changed as we read it? when using tar (GNU tar).  The upgrade to 3.8.5 was
performed following the ?online upgrade procedure?.

My current configuration:

	- CentOS 7.2 64bits
	- Gluster 3.8.5 from RPM repo
	- Bricks: 3 x 2 = 6
	- cluster.op-version = 30800
	- NTP on all servers
	- 10 GbE interconnections
	- MTU 9000
	- GNU tar 1.26

The warning message appears on different files every time a tar file is created
with the same source.

	tar: /gluster_volume/2016-11-28_05-00-01/d1/t1.ibd: file changed as we read it
	tar: /gluster_volume/2016-11-28_05-00-01/d2/t2.ibd: file changed as we read it
	tar: /gluster_volume/2016-11-28_05-00-01/d3/t3.frm: file changed as we read it
	tar: /gluster_volume/2016-11-28_05-00-01/d4/t4.frm: file changed as we read it

Any advise on how to start debugging this problem? I missed something on the
upgrade?
