Alex,

I can't reproduce on my baremetal T5120 (sun4v) installed with debian
sparc64, using kernel 4.7.0-rc4+ (git).

used the following as a cycle rsync copy:

mator@nvg5120:~$ du -sh debian-installer  linux-2.6 v7.4.1a gcc-6.1.0
494M    debian-installer
2.6G    linux-2.6
1.2G    v7.4.1a
832M    gcc-6.1.0

mator@nvg5120:~$ cnt=0; while true; do let cnt++; echo $cnt; sleep 2;
rm -rf testdir; rsync -a debian-installer linux-2.6 gcc-6.1.0 v7.4.1a
testdir; done
1
2
3
4
5
6
7
8
9
10
^C

Can you please tell, what is /export/test/* ? Is it big files vs small
files, what is directory structure ?

Thanks.
