<div dir="ltr"><div><div><div><div>Hi,<br><br></div>I am planning an ovirt hosted-engine installation with two nodes and an iSCSI SAN for the engine and VMs and NFS for ISO and Export domains, on another NAS.<br><br></div><div>The iSCSI SAN have two controllers, each one have two NICs at 1Gb/s, and I was planning to use a bond manually configured (two NICs) on hypervisors/nodes, so I'll end up with 4 paths.<br><br></div><div>- Creating a bond is it a good idea? or do I have to use the node NICs separately as in the link mentioned earlier?<br><br></div>- If I'll use a bond, will it survive the engine's installation?<br><br>- After the engine's installation, the link(s)/path(s) used to connect
to the SAN storage will also be used to connect to the NAS, this will
constitute a storage network, this network will be mandatory so I can't
create an iSCSI bond on top of it. Will the multipath be configured automatically by the engine's installation on all hypervisors/nodes?<br></div><br></div><div></div><div>thanks in advance.<br></div></div><div class="gmail_extra"><br><div class="gmail_quote">2015-03-24 10:30 GMT+01:00 Simone Tiraboschi <span dir="ltr"><<a href="mailto:stirabos@redhat.com" target="_blank">stirabos@redhat.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br>

In 3.5 is not directly supported from assisted setup.<br>
Basically you have to manually pre-connect the storage on each involved host and manually persist that configuration.<br>
<br>
You can find some hint there:<br>

<br>
Adding Nir to double check it.<br>
