<div>Hi all, <br>
<br>
</div>
I have a cluster with 3 nodes, using ovirt 4.1 in a self hosted setup on top glusterfs. </div>
On some VMs (especially one Windows server 2016 64bit with 500 GB of disk). Guest agents are installed at VMs. i almost always observe that during the backup of the VM the VM is rendered unresponsive (dashboard shows a question mark at the VM status and VM
does not respond to ping or to anything). <br>
<br>
</div>
For scheduled backups I use:

<p style="margin-bottom:0in; line-height:100%"><font face="Courier 10 Pitch"><font size="2" style="font-size:10pt">The script does the following:<br>

<p style="margin-bottom:0in; line-height:100%"><font face="Courier 10 Pitch"><font size="2" style="font-size:10pt">1. snapshot VM (this is done ok without any failure)<br>
</font></font></p>
<p style="margin-bottom:0in; line-height:100%"><font face="Courier 10 Pitch"><font size="2" style="font-size:10pt">2. Clone snapshot (this steps renders the VM unresponsive)<br>
</font></font></p>
<p style="margin-bottom:0in; line-height:100%"><font face="Courier 10 Pitch"><font size="2" style="font-size:10pt">3. Export Clone</font></font></p>
<p style="margin-bottom:0in; line-height:100%"><font face="Courier 10 Pitch"><font size="2" style="font-size:10pt">4. Delete clone</font></font></p>
<p style="margin-bottom:0in; line-height:100%"><font face="Courier 10 Pitch"><font size="2" style="font-size:10pt">5. Delete snapshot</font></font></p>
<p style="margin-bottom:0in; line-height:100%"><font face="Courier 10 Pitch"><font size="2" style="font-size:10pt"><br>

<p style="margin-bottom:0in; line-height:100%"><font face="Courier 10 Pitch"><font size="2" style="font-size:10pt">Do you have any similar experience? Any suggestions to address this?</font></font></p>

<p style="margin-bottom:0in; line-height:100%"><font face="Courier 10 Pitch"><font size="2" style="font-size:10pt">The cluster has enough storage to accommodate the clone.
