Description of problem:
I am getting the error "fio: end_fsync failed for file
FS_4k_streaming_writes.1.0 unsupported operation" while running with libgfapi
on gluster volume.

How reproducible:
Always

Steps to Reproduce:

1. install gluster v3.6.1 one machine 1 (Ex: 192.168.1.246)

2. install fio from https://github.com/axboe/fio on machine 2 (Ex:
192.168.1.245)

3. # fio $args --output=4k_stream_writes.log --section=FS_4k_streaming_writes
--ioengine=gfapi --volume=vol1 --brick=192.168.1.246 fsmb.fio

Actual results:
fio: end_fsync failed for file FS_4k_streaming_writes.1.0
unsupported operation.(1),W(1),_(1)] [87.8% done] [0KB/117.2MB/0KB /s]
[0/30.3K/0 iops] [eta 00m:05s]
fio: end_fsync failed for file FS_4k_streaming_writes.2.0
unsupported operation.(3)] [94.9% done] [0KB/116.4MB/0KB /s] [0/29.7K/0 iops]
[eta 00m:02s]          
fio: end_fsync failed for file FS_4k_streaming_writes.0.0
unsupported operation.[33.8% done] [0KB/118.2MB/0KB /s] [0/15.2K/0 iops] [eta
00m:43s]


Expected results:
Fio should complete with flying numbers (bandwidth, iops, ...) :)
