Thoughts about Adding Storage Luns 

As I am new here, I would appreciate some advice about some actions that I 
intend to perform, please read. 

I have added a LUN to my cluster and, for that task, I had to restart every 
node of it. There was no LUNs before, multipathd was stopped and multipath.conf 
inexisted. I was able to log in and manually configure multipath.conf, a simple 
multipathd start was not enough. 

If this wasn't enough, my double NetAPP ( through an Hitachi ) provided me with 
a not so empty brand new LUN, and the task to add the FCP failed to point this. 
Trusting my double, I spent some precious time searching for different 
problems, until receiving some guidance and do a simple dd if=/dev/zero to the 
initial blocks of the LUN. 

Consulting the documentation ( 
http://www.ovirt.org/OVirt_Administration_Guide#Adding_FCP_Storage ) for this 
matters, was not of any help. 

So, my questions: 

This is the intended behavior? Should I open a ticket? 

Should I add a note to documentation to point such behavior? ( i'm about to ) 


Cheers,
