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

[Dustin Black]

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
