[Gluster-devel] Need help in understanding IOZone config file

[Menaka Mohan]

Hello,


Thank you so much for helping me in understanding it.  I have read more about that and with the help of other community members, I submitted a pull request to update it in the Gluster docs [1] for better understanding which was accepted and merged.


Since each record in the config file represents a thread in IOZone terminology, we may need to have as many records with respect to the number of threads defined and number of clients in our setup.

Thanks and Regards,

Menaka M

Hi Menaka,

We test Gluster with something like this using iozone for 4GB file sizes.

iozone -t 6 -s 4g -r 4m -+m clients.ioz -c -e -+z -+n -i 0 && iozone -t 6 -s 4g -r 4m -+m clients.ioz -c -e -+z -+n -i 1


Where the clients.ioz file might look like the below for 6 clients/workers:

c0 /path/to/gluster/client/mount /path/to/binary/iozone
c1 /path/to/gluster/client/mount /path/to/binary/iozone
c2 /path/to/gluster/client/mount /path/to/binary/iozone
c3 /path/to/gluster/client/mount /path/to/binary/iozone
c4 /path/to/gluster/client/mount /path/to/binary/iozone
c5 /path/to/gluster/client/mount /path/to/binary/iozone

Hi,


I am Menaka M. I am new to this open source world. Kindly help me with the following query.


I have set up the Gluster development environment with two servers and one client. I am trying to run the basic bench test on the Gluster cluster from this GitHub repo<https://github.com/gluster/gbench/tree/master/bench-tests/bt-0000-0001>. I also have IOZone installed. In that, how to generate the clients.ioz file (prerequisite 3) ? Does that refer to the file containing (client_name   work_dir    path_to_IOZone_on_client) ?


I have read multiple blogs on how to analyze the IOZone results and also the performance testing section in docs. Kindly help me resolve this confusion. If I had asked a very basic thing, apologies. I will quickly learn them.


Regards,

Menaka M
