Note that Gluster hasn't all the VSAN features yet so you will be able to replicate data.<br>

Also I personally think replica=3 is overkill and waste of space for mos scenarios. 2 should be enough and give a raid 1 like.</blockquote><div><br></div><div>I'm not sure it's like RAID 1.

Hi,<br>
<br>
We are trying to create a setup that uses the internal disks of the<br>
hosts / nodes, yet provide the high availability, replication and<br>
failover using oVirt. The setup we are typing to build is close to<br>
VMWare VSAN which allows for all the above just using the internal disks<br>
of the ESXi servers.<br>
<br>
Can we achieve something similar with oVirt with Gluster?<br>
</blockquote>
<br>
Absolutely. One of our oVirt setup is done this way.<br>
Three hosts are set up as glusterFS servers (replica-3), as well as oVirt nodes.<br>
We choose to add a fourth host as an standalone engine, but you can choose to use a VM for that (hyperconverge setup).<br>
<br>
I have no experience on similar setup with a random number of nodes, neither if this can be achievable (some kind of network RAID-10)... (?)<br>
