<p dir="ltr">Hello Community,</p>
<p dir="ltr">I'm making some changes and I would like to hear  your opinion on the topic.</p>
<p dir="ltr">First, let me share my setup.<br>
I have 3 systems with in a replica 3 arbiter 1 hyperconverged setup (oVirt) which use 1 gbit networks for any connectivity.</p>
<p dir="ltr">I have added 4 dual-port 1 gbit NICs ( 8 ports per machine in total) and connected them directly between ovirt1 and ovirt2 /data nodes/ with LACP aggregation (layer3+layer4 hashing).</p>
<p dir="ltr">As ovirt1 & ovirt2 are directly connected /trying to reduce costs by avoiding the switch/ I have setup /etc/hosts for the arbiter /ovirt3/ to point tothe old IPs .</p>
<p dir="ltr">So they look like:<br>
ovirt1 & ovirt2 /data nodes/ /etc/hosts:</p>
<p dir="ltr"><a href="http://127.0.0.1">127.0.0.1</a> localhost localhost.localdomain localhost4 localhost4.localdomain4<br>
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6<br>
<a href="http://192.168.1.90">192.168.1.90</a> ovirt1.localdomain ovirt1<br>
<a href="http://192.168.1.64">192.168.1.64</a> ovirt2.localdomain ovirt2<br>
<a href="http://192.168.1.41">192.168.1.41</a> ovirt3.localdomain ovirt3<br>
<a href="http://10.10.10.1">10.10.10.1</a> gluster1.localdomain gluster1<br>
<a href="http://10.10.10.2">10.10.10.2</a> gluster2.localdomain gluster2</p>
<p dir="ltr">ovirt3 /etc/hosts:</p>
<p dir="ltr"><a href="http://127.0.0.1">127.0.0.1</a> localhost localhost.localdomain localhost4 localhost4.localdomain4<br>
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6<br>
#As gluster1 & gluster2 are directly connected , we cannot reach them.<br>
<a href="http://192.168.1.90">192.168.1.90</a> ovirt1.localdomain ovirt1 gluster1<br>
<a href="http://192.168.1.64">192.168.1.64</a> ovirt2.localdomain ovirt2 gluster2<br>
<a href="http://192.168.1.41">192.168.1.41</a> ovirt3.localdomain ovirt3</p>
<p dir="ltr">Do you see any obstacles to 'peer probe' and then 'replace brick' the 2 data nodes.<br>
Downtime is not an issue, but I preffer not to wipe the setup.</p>
<p dir="ltr">Thanks for reading this long post and don't hesitate to recommend any tunings.<br>
I am still considering what values to put for the client/server thread count.</p>
<p dir="ltr">Best Regards,<br>
