I checked the database using the same command that engine-setup uses:
engine=> select vds_id, ha_global_maintenance from vds_statistics ;
vds_id | ha_global_maintenance
--------------------------------------+-----------------------

(4 rows)
And it sure isn't in global maintenance even though all the hosted engine hosts show that it is in global maintenance. Do I manually change those flags, that seems dangerous...
