<div dir="ltr"><div><div><div><div><div><div><div><div><div>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></div>EG: Given the following example<br>
<br></div>Storage Domain A (Master) --> NFS --> Storage Server 1<br></div>Storage Domain B --> NFS --> Storage Server 2<br><br></div>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></div>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></div>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></div>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></div>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><br></div>- DHC<br>
