Definitely is a challenge trying to replace a bad host.

So let me tell you what I see and have done so far:

1.-I have a host that went bad due to HW issues.
2.-This bad host is still showing in the compute --> hosts section.
3.-This host was part of a hyperconverged setup with Gluster.
4.-The gluster bricks for this server show up with a "?" mark inside the volumes under Storage ---> Volumes ---> Myvolume ---> bricks
5.-Under Compute ---> Hosts --> mybadhost.mydomain.com the host  is in maintenance mode.
6.-When I try to remove that host (with "Force REmove" ticked) I keep getting:
    Operation Canceled
             Error while executing action:
    mybadhost.mydomain.com
            - Cannot remove Host. Server having Gluster volume.
Note: I have also confirmed "host has been rebooted"

Since the bad host was not recoverable (it was fried), I took a brand new server with the same specs and installed oVirt 4.3.3 on it and have it ready to add it to the cluster with the same hostname and IP but I cant do this until I remove the old entries on the WEB UI of the Hosted Engine VM.

If this is not possible would I really need to add this new host with a different name and IP? 
What would be the correct and best procedure to fix this?

Note that my setup is a 9 node setup with hyperconverged and replica 3  bricks and  in a  distributed replicated volume scenario.

Thanks
