[ovirt-users] Error while executing action: Cannot add Host. Host with the same UUID already exists.

[ml at ohnewald.net]

Hello List,

i am using  oVirt Engine Version: 3.5.2.1-1.el6.

I would like to remove a node from a GlusterFS Cluster and use it for 
local storage.

So i put my node into maintance. Reinstalled it freshly with CentOS7.

Now i would like to add it to a New Cluster with local storage, but i get:

Error while executing action: Cannot add Host. Host with the same UUID 
already exists.



How can i resolve this problem?


I can NOT remove my old host from the Gluster: Cannot remove Host. 
Server having Gluster volume.



Thanks,
Mario
