Description hari gowtham 2016-08-30 13:05:30 UTC

+++ This bug was initially created as a clone of Bug #1169236 +++

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, ...) :)

Hi Kiran,

could you let us know if you hit any issues with fio over a fuse mount?
Also, what kind of volume are you running the tests against?

Thanks,
Niels

Hi Niels,

I will try with fuse mount.

I am using distributed volume.

Thanks,
Kiran.

Comment 1 Niels de Vos 2016-09-12 05:38:25 UTC

All 3.8.x bugs are now reported against version 3.8 (without .x). For more information, see http://www.gluster.org/pipermail/gluster-devel/2016-September/050859.html

Comment 2 Niels de Vos 2017-11-07 10:37:11 UTC

This bug is getting closed because the 3.8 version is marked End-Of-Life. There will be no further updates to this version. Please open a new bug against a version that still receives bugfixes if you are still facing this issue in a more current release.
