Something like the current fencing option for “50% hosts down” as a double check, if you can still reach the vdsm hosts, don’t restart the engine vm.</div><div class=""><br class=""></div><div class=""> -Darrell<br class=""><div><blockquote type="cite" class=""><hr style="border:none;border-top:solid #B5C4DF 1.0pt;padding:0 0 0 0;margin:10px 0 5px 0;" class=""><span style="margin: -1.3px 0.0px 0.0px 0.0px" id="RwhHeaderAttributes" class=""><font face="Helvetica" size="4" color="#000000" style="font: 13.0px Helvetica; color: #000000" class=""><b class="">From:</b> Yaniv Kaul <<a href="mailto:ykaul@redhat.com" class="">ykaul@redhat.com</a>></font></span><br class="">
