<p class=MsoNormal>This completely froze the entire cluster, when ESX tried to
v-motion 3 of 6 nodes to a new host. <o:p></o:p></p>
<p class=MsoNormal>Is it recommended by Oracle not to enable DRS on virtual
machine using the cluster, or is there a configuration we can use to keep
crashes like this from happening all the time.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have seen several posts suggesting that disabling DRS
would be a “way to workaround” this issue but not really a good
practice as you would loose a lot of your HA abilities.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Also is there a way to have OCFS2 drop a node from the
cluster if a new node comes online with its ID?<o:p></o:p></p>
