If the VMs are on the replica 1 volume (and they should),  converting to 'replica 3' will just copy the data between the nodes.

Check in the UI the volume type , brick count, etc.

I guess you will need to add the two hosts, which oVirt will automatically add them in Gluster Cluster. You can then open the UI and create the bricks and change the volume.

You can also do it from cli and once adding the hosts, then they will be automatically detected properly.

Always test properly on a non-prod environment.

So that way, the new hosts will copy the data from the already provisionned vmstore?

You might just add the new host via Engine UI, then through the UI you can create the bricks and modify the volume .

Of course you can go via cli.
