Hello,
<div class=""><br class="">
</div>
<div class="">I’m joining the crowd with iSCSI Multipath issues on oVirt here. I’m trying to enable the feature without success too.</div>
<div class=""><br class="">
</div>
<div class="">Here’s what I’ve done, step-by-step.</div>
<div class=""><br class="">
</div>
<div class="">1. Installed oVirt Node 4.1.3 with the following network settings:</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>eno1 and eno2 on a 802.3ad (LACP) Bond, creating a bond0 interface.</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>eno3 with 9216 MTU.</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>eno4 with 9216 MTU.</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>vlan11 on eno3 with 9216 MTU and fixed IP addresses.</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>vlan12 on eno4 with 9216 MTU and fixed IP addresses.</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>eno3 and eno4 are my iSCSI MPIO Interfaces, completelly segregated, on different switches.</div>
<div class=""><br class="">
</div>
<div class="">2. Started the installation of Self-hosted engine after three hours of waiting, because:
<a href="https://bugzilla.redhat.com/show_bug.cgi?id=1454536" class="">https://bugzilla.redhat.com/show_bug.cgi?id=1454536</a></div>
<div class=""><br class="">
</div>
<div class="">3. Selected iSCSI as default interface for Hosted Engine. Everything was fine.</div>
<div class=""><br class="">
</div>
<div class="">4. On the Hosted Engine I’ve done the following:</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>a. System > Data Centers > Default > Networks</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span></div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>. Created iSCSI1 with VLAN 11 and MTU 9216, removed VM Network option.</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>. Created iSCSI2 with VLAN 12 and MTU 9216, removed VM Network option.</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>b. System > Data Centers > Default > Clusters > Default > Hosts >
<a href="http://ovirt3.cc.if.ufrj.br" class="">ovirt3.cc.if.ufrj.br</a> (my machine)</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>Selected Setup Host Networks and moved iSCSI1 to eno3 and iSCSI2 to eno4. Both icons gone green, indicating an “up” state.</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>c. System > Data Centers > Default > Clusters</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>Selected Logical Networks and them Manage Network. Removed the Required checkbox from both iSCSI connections.</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>d. System > Data Centers > Default > Storage</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>Added an iSCSI Share with two initiators. Both shows up correctly.</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>e. System > Data Centers</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>Now the iSCSI Multipath tab is visible. Selected it and added an iSCSI Bond:</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>. iSCSI1 and iSCSI2 selected on Logical Networks.</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>. Two iqn’s selected on Storage Targets.</div>
<div class=""><br class="">
</div>
<div class="">5. oVirt just goes down. VDSM gets crazy and everything “crashes”. iSCSI is still alive, since we can still talk with the Self Hosted Engine, but **NOTHING** works. If the iSCSI Bond is removed everything regenerates to a usable state.</div>
<div class=""><br class="">
</div>
<div class="">I’ve added the following files on my public page to help on debugging:</div>
<div class="">/var/log/vdsm/vdsm.log</div>
<div class="">/var/log/sanlock.log</div>
<div class="">/var/log/vdsm/mom.log</div>
<div class="">/var/log/messages</div>
<div class=""><br class="">
</div>
<div class="">There are some random images of my configuration too: <a href="http://www.if.ufrj.br/~ferrao/ovirt/" class="">http://www.if.ufrj.br/~ferrao/ovirt/</a></div>
<div class=""><br class="">
</div>
<div class="">What should be done now? Issue a bug fix request?</div>
<div class=""><br class="">
</div>
<div class="">Thanks,</div>
<div class="">V.</div>

<div class="">PS: My machine is reachable over the internet. So if anyone would like to connect to it, just let me know.</div>
