</span><!--[endif]-->Wanted to move to RHEL6.5 and hence the
underlying cluster. Also wanted to move to recommended way of using cluster
with CMAN using “cluster.conf”.<o:p></o:p></p><p class="MsoListParagraphCxSpLast" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><br></p><p class="MsoListParagraphCxSpLast" style="text-indent:-.25in;mso-list:l0 level1 lfo1">(<span style="font-size: 12pt;">Before executing this document I first upgraded my O/S to RHEL6.5.</span><span style="font-size: 12pt;">)</span></p>
<p class="MsoNormal">To solve this problem , found following link:<o:p></o:p></p>

<p class="MsoNormal">(Also got another link which has more or less same thing
explain in a documented way:<o:p></o:p></p>

<p class="MsoNormal"><br></p><p class="MsoNormal">This document is written well and I could execute all of the
commands successfully without disturbing my cluster, but I found some issue
after executing this last line:<o:p></o:p></p>
<p class="MsoNormal">crm configure property maintenance-mode=false<o:p></o:p></p>
<p class="MsoNormal">After executing this command, I lost my VIP. I need to
execute this upgrade on my production environment and can’t afford to go “offline”
in this way.<o:p></o:p></p>
<p class="MsoNormal"><br></p><p class="MsoNormal">Few are my questions to execute this upgrade in a more convenient
way:<o:p></o:p></p>

</span><!--[endif]-->What can be the reason of this VIP removal (if
someone has already tested with this approach)?<o:p></o:p></p>

</span><!--[endif]-->Is it right approach, if I do directly assign my
VIP (after moving my cluster to maintenance mode) to one of my Ethernet interface
and then run the commands given in this document.<o:p></o:p></p>

</span><!--[endif]-->Is not there some command line option to upgrade
from corosync.conf to cluster.conf directly(ideally I felt that we should be
able to generate an ).<o:p></o:p></p>

</span><!--[endif]-->How will I move to the usage of “pcs commands”. This
article is given with using “ccs” commands. Shall I assume that once I finish
with “ccs”, I can do rest of my configuration using “pcs” commands.<o:p></o:p></p><p class="MsoListParagraphCxSpLast" style="text-indent:-.25in;mso-list:l1 level1 lfo2"><br></p><p class="MsoListParagraphCxSpLast" style="text-indent:-.25in;mso-list:l1 level1 lfo2">Regards,</p><p class="MsoListParagraphCxSpLast" style="text-indent:-.25in;mso-list:l1 level1 lfo2">Parveen Jain</p> </div></body>
