I read at <a href="https://www.ovirt.org/develop/projects/node/troubleshooting/" rel="noreferrer" target="_blank">https://www.ovirt.org/develop/<wbr>projects/node/troubleshooting/</a>
that "Changes made from the command line are
done at your own risk. Making changes has the
potential to leave your system in an unusable
state." It seems clear that RPMs should not be
installed.<br>

<div>That document mainly refers to vintage node.</div>
<div>In Next Generation Node now we have rpm persistence;
please check</div>

I'm sure glad we tested! <br>
<br>
On one Node image we had images locally stored in /exports and
shared out via NFS. After an upgrade & reboot, images are gone.<br>
<br>
If we "Convert to local storage" will the data persist? I am
planning to test, but want to be sure how this is designed.<br>
<br>
I assume during a Gluster installation something is also updated in
oVirt Node to allow for the Gluster partition to persist?<br>
<br>
At this point I'm thinking I should manually install via CentOS7 to
ensure folders and partitions are persistent. Is there any downside
to installing over CentOS7?<br>
<br>
