It's actually not so easy.
The fastest way to recover is just restore from backup.
Otherwise the flow should be:
1. Install the new node (new hostname will be easier).
2. Use gluster's replace-brick to change the dead brick with new one.
3. Once ovirt 's integration with gluster detects the change, you will be
able to forcefully remove the dead node.
4. Add the newly installed node to the relevant cluster (with or without
hosted-engine deployment)
5. Test to move a low-priority VM to the new host.
6. Power up a test VM on the new host to test the functionality.
7. You can make the new node SPM and test snapahots and new vm creation.
As you can see , in order to remove a missing node - it should not be part of
the Gluster Cluster.
