Adding another question to what Matthias has said.
<div class=""><br class="">
</div>
<div class="">I also noted that oVirt (and RHV) documentation does not mention the supported block size on iSCSI domains.</div>
<div class=""><br class="">
</div>
<div class="">RHV: <a href="https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.0/html/administration_guide/chap-storage" class="">https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.0/html/administration_guide/chap-storage</a></div>
<div class="">oVirt: <a href="http://www.ovirt.org/documentation/admin-guide/chap-Storage/" class="">http://www.ovirt.org/documentation/admin-guide/chap-Storage/</a></div>
<div class=""><br class="">
</div>
<div class="">I’m interested on 4K blocks over iSCSI, but this isn’t really widely supported. The question is: oVirt supports this? Or should we stay with the default 512 bytes of block size?</div>

<div class="">Thanks,</div>

Thanks, Konstantin.<br class="">
Just to be clear enough: the first deployment would be made on<br class="">
classic eth interfaces and later after the deployment of Hosted<br class="">
Engine I can convert the "ovirtmgmt" network to a LACP Bond, right?<br class="">
Another question: what about iSCSI Multipath on Self Hosted Engine?<br class="">
I've looked through the net and only found this issue:<br class="">
<a href="https://bugzilla.redhat.com/show_bug.cgi?id=1193961" class="">https://bugzilla.redhat.com/show_bug.cgi?id=1193961</a><br class="">
<<a href="https://bugzilla.redhat.com/show_bug.cgi?id=1193961" class="">https://bugzilla.redhat.com/show_bug.cgi?id=1193961</a>><br class="">
Appears to be unsupported as today, but there's an workaround on the<br class="">
comments. It's safe to deploy this way? Should I use NFS instead?<br class="">
It's probably not the most tested path but once you have an engine you should be able to create an iSCSI bond on your hosts from the engine.<br class="">
Network configuration is persisted across host reboots and so the iSCSI bond configuration.<br class="">
A different story is instead having ovirt-ha-agent connecting multiple IQNs or multiple targets over your SAN. This is currently not supported for the hosted-engine storage domain.<br class="">
See:<br class="">

Hi Simone,<br class="">
<br class="">
i think my post to this list titled "iSCSI multipathing setup troubles" just recently is about the exact same problem, except i'm not talking about the hosted-engine storage domain. i would like to configure _any_ iSCSI storage domain the way you describe it
in <a href="https://bugzilla.redhat.com/show_bug.cgi?id=1149579#c1" class="">https://bugzilla.redhat.com/show_bug.cgi?id=1149579#c1</a>. i would like to do so using the oVirt "iSCSI Multipathing" GUI after everything else is setup. i can't find a way to do
this. is this now possible? i think the iSCSI Multipathing documentation could be improved by describing an example IP setup for this.<br class="">
<br class="">
thanks a lot<br class="">
matthias<br class="">
