I have never done this , so you can simulate it on VMs before doint it : 1. Add the new host and put it in maintenance 2. You can backup your Hosted Engine VM and any critical VMs(just incase) 3. Create a new Gluster volume (either replica 3 or replica 2 arbiter 1) 4. Add the new volume via the UI as new storage 5. Do a storage migration from the distributed to the replica 3 volume. 6. Get rid of the old distributed volume and use it for something useful. 7. Remove the new hosts' maintenance and test live migration 8. Set global maintenance (via hosted-engine command) and poweroff the engine VM. 9. Manually power it up on a new host. 10. Remove global maintenance and shutdown a VM 11. Change the same VM to power up only on specific host and power it up. 12. Remove the limitation of that test VM (from step 10 & 11) And you are ready to go.

Hello currently i have a server running glusterfs on distributed 1 and a self hosted engine. And planning to add two servers for hci.

Do i add new hosts and change gluster volume type to replicated or backup all the vms then start from scratch?

Is there any recommendation on this?
