--- Comment #8 from Saravanakumar <sarumuga at redhat.com> ---
Updating my observation:

18k empty files created, able to sync to slave(in geo-rep setup) .

==================================================
NON-tier volume: 3x2 volume

[root at gfvm3 non-tierd_volume]# echo 3 > /proc/sys/vm/drop_caches
[root at gfvm3 non-tierd_volume]# time ls
..
real    0m10.130s
user    0m0.194s
sys    0m0.345s
[root at gfvm3 non-tierd_volume]#

==================================================
Tier Volume : 3x2 cold tier , 2x2 hot tier

[root at gfvm3 tierd_volume]# echo 3 > /proc/sys/vm/drop_caches
[root at gfvm3 tierd_volume]# time ls
