If the hostname of a node host changes after its initial setup, applications with existing gears on that node host can become inaccessible to an OpenShift Enterprise user. Many other problems can result as well. To help detect this issue, the oo-admin-chk command now checks whether the current hostname of a reporting node host matches what is recorded in the datastore for any gear discovered on that node host. This may briefly report problems if a gear is being moved at the time the command is run, but should otherwise be considered a legitimate issue. Detecting and correcting this issue also helps prevent future upgrade problems.
