Tibor,

This is not an officially supported solution, but I had a similar issue myself 
at some point (virtual gluster hosts that I was silly enough to delete without 
first stopping the volumes). Basically the status of the volumes is stored in 
the gluster_volumes table, status column. If you manually update the status to 
be 'DOWN' instead of 'UP' for the volumes that are giving you trouble. Then in 
the UI they will be down as well. At which point you should be able to 
properly remove them from the UI using the UI.

Once that is done you should be able to simply remove the offending hosts as 
there are no longer any gluster volumes associated with it.

I am sure there is a much better way of doing this (maybe REST api?), but I 
couldn't find it (I am not a gluster expert).
