It can be good idea:
2 physical nodes with local disks (raid6) as gluster bricks + 2 kvm vms with pcs and drbd for arbiter.

I'll test it.

Yes, I checked it but it seems I still need three nodes - 2 for storage and one smaller for arbiter.

Is it safe to deploy it only on two nodes?

the host arbiter can be even just a Raspberry PI as far as I can tell.

Adding Sahina.

 

Am I wrong?

Hello, currently I'm using kvms with pcs&drbd on vms... is there any ovirt solution for ha with two nodes (storage on local disks) without pcs& drbd for storage? I know about gluster storage but it needs third host;/

Did you check https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.3/html/administration_guide/creating_arbitrated_replicated_volumes ?
