Can we achieve something similar with oVirt with Gluster?
Absolutely. One of our oVirt setup is done this way. Three hosts are set up as glusterFS servers (replica-3), as well as oVirt nodes. We choose to add a fourth host as an standalone engine, but you can choose to use a VM for that (hyperconverge setup). 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)... (?) -- Nicolas ECARNOT

Hello Note that Gluster hasn't all the VSAN features yet so you will be able to replicate data. 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. On 31/01/2017 06:29, Nicolas Ecarnot wrote:

I'm not sure it's like RAID 1. In RAID 1, when one disk fails, I'm pretty sure I know where the correct data is. In Gluster, if you have a split brain, where's the correct data? I suggest perhaps using an arbiter. Y.
