Description of problem:
I am running fio latest from master branch with below configuration on gluster
v3.6.1 CentOS v6.6 and it is failing.

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_caranred_gz.log --section=FS_cached_4k_random_reads
--ioengine=gfapi --volume=vol1 --brick=192.168.1.246 fsmb.fio

4. # fio $args --output=4k_caranredmt_gz.log
--section=FS_multi-threaded_cached_4k_random_reads --ioengine=gfapi
--volume=vol1 --brick=192.168.1.246 fsmb.fio


Actual results:
fio: failed to lseek pre-read file[0KB/0KB/0KB /s] [0/0/0 iops] [eta
1158050440d:23h:16m:01s]

fio: failed to lseek pre-read file[0KB/0KB/0KB /s] [0/0/0 iops] [eta
1158050440d:23h:12m:37s]
fio: failed to lseek pre-read fileone] [0KB/0KB/0KB /s] [0/0/0 iops] [eta
1158050440d:23h:12m:33s]
fio: failed to lseek pre-read fileone] [4KB/0KB/0KB /s] [1/0/0 iops] [eta
1158050440d:23h:12m:32s]
fio: failed to lseek pre-read file


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