<p>Sometimes a host becomes non-responsive due to an unexpected problem,
and though VDSM is unable to respond to requests, the virtual machines
that depend upon VDSM remain alive and accessible. In these situations,
restarting VDSM returns VDSM to a responsive state and resolves this
issue.
</p><p>oVirt 3.3 introduces "soft-fencing over SSH". Prior to oVirt 3.3,
non-responsive hosts were fenced only by external fencing devices. In
oVirt 3.3, the fencing process has been expanded to include "SSH Soft
Fencing", a process whereby oVirt attempts to restart VDSM via SSH on
non-responsive hosts. If oVirt fails to restart VDSM via SSH, the
responsibility for fencing falls to the external fencing agent if an
external fencing agent has been configured. <br></p><p><b>BUT, It does NOT say how to set it up? <br></b></p><p><b>is there any step by step doc for it? </b><br></p><p><br></p><p>HOPE TO hear from you? <br></p><p><br></p></div><div><br></div><div><br><br><br><br> <br><div><div><div>-- <br><div><div dir="ltr">cat /etc/motd<br><br>Thank you<br>Indunil Jayasooriya <br><a href="http://www.theravadanet.net/" target="_blank">http://www.theravadanet.net/</a><br><a href="http://www.siyabas.lk/sinhala_how_to_install.html" target="_blank">http://www.siyabas.lk/sinhala_how_to_install.html</a> - Download Sinhala Fonts<br><br></div></div>
