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

How about just pausing the VM's from webadmin, shut engine down, do maintenance, start engine back up and then run the VM's again?<br>
