Thank you Fred for your answer, <br>
Aharon suggests me :<br>
<div>"<br>
The flow should be like below - <br>
</div>
<ul>
<li>Put the relevant domain in maintenance</li>
<li>Extend the lun (from storage side)<br>
</li>
<li>Resize the relevant PV (f<span class="quote">or example - >
"pvresize --setphysicalvolumesize 125G >
/dev/mapper/3600601601282300056f0075c3f81e311"</span><br>
</li>
<li>Activate the domain</li>
</ul>
Check the storage domain total size, It should have the new size.<br>
"<br>
<br>
I have a few question to do it manually:<br>
<ul>
<li>Do I have to shutdown or live storage migrate to an other lun
all my vms to perform the pv extend on the SPM? I know now it
won't update the ovirt db but, is it a risk to do extend this in
production?</li>
<li>My next question is : is it possible to fill manually the new
lun size in the DB?</li>
</ul>
<p>All this would prevent me from a heavy maintenance or from a very
long migration (4TB) due to maintenance mode.<br>

Subject: [ovirt-users] expanding a lun on the san side
Hi all,
I've just expanded the lun used as master by the domain storage. fdisk
on the SPM is able to see the multipath device with its new size, but
engine reports the old size.
How to refresh this?
