Is there any method of designating which domain should be the master<br>
storage domain or forcibly changing the role to a different storage domain?<br>
<br>
EG: Given the following example<br>
<br>
Storage Domain A (Master) --> NFS --> Storage Server 1<br>
Storage Domain B --> NFS --> Storage Server 2<br>
<br>
One wants to do maintenance to Storage Server 1 but in doing so the<br>
Master storage domain is hosted from Storage Server 1. Thus the net<br>
result of taking down Storage Server 1 is that one must also take down<br>
Storage Server 2.<br>
<br>
Thus we know we must shut down VM's from Storage Domain A to maintenance<br>
Storage Server 1. Suppose however that VM's are running that we don't<br>
want to shut down and are hosted from Storage Domain B via Storage Server 2.<br>
<br>
We would want to be able to promote Storage Domain B to Master so that<br>
we can take down Storage Domain A to do maintenance to Storage Server 1.<br>
<br>
Once we are done with maintenance to Storage Server 1 we can bring<br>
Storage Domain A back on line, re-designate it as Master if desired and<br>
bring it's VM's back online.<br>
<br>
I know I have seen this occur automatically to a point when a Storage<br>
Domain goes missing that is the Master Domain but I have not noted any<br>
manual method of doing so given the above scenario.<br>

<br>
my understanding is you can move the storage domain A which is master to maint. engine will promote storage domain B to master and everything should continue working as is.<br>
