Please bring down all glusterd instances before correcting the files. So you should first stop the glusterd services, repair the files (removing unwanted entries), ensure the peer files content are correct across all nodes and then start the glusterd service on each node one by one.

but it re-adds the nas28 at each service glusterd restart.
Is there something else to delete?
