Dynamo and Linux - IOmeter on Win2008R2

Mike Jensen

Linux newbie here.

I have run dnamo on RH linux in the past, and now attempting it on Debian – kernel info below…

 

root@DellR620-35:~# uname -a

Linux DellR620-35 3.7.10-bgrml64-05 #1 SMP Tue Jun 11 14:59:40 CDT 2013 x86_64 GNU/Linux

root@DellR620-35:~#

 

The command line used is immediately below and the reaction from IOmeter on Windows.  I want to test raw devices - /dev/sdc,…

These are just SAS disks being presented in JBOD chassis via LSI SAS HBA.  I was thinking that the reference to iobw.txt was only invoked when the storage had a file system mounted on it.  This could also be a protection issue (permission denied…)

I think the firewall is off.

 

Appreciate any assistance/expertise

 

 

 

root@DellR620-35:/usr/local/bin# ./dynamo -i 10.148.3.30 -m 10.148.1.70
