It seems that it is not supported in oVirt yet? I got this response
when I tried to change master with those storage domain that I have:
<?xml version="1.0" encoding="UTF-8"
standalone="yes"?>
<fault>
<detail>[Cannot switch master storage domain. Switch master
storage domain operation is not supported.]</detail>
<reason>Operation Failed</reason>
</fault>
So is this really the only way to do this: shutdown everything and put
other storage domains into maintenance? It would have been nice if
this information was in the upgrade guide. It made this seem so easy
and simple...
Thanks,
Juhani
