Hi Sandvik,

Executing the following (all one line) on your engine machine will list 
the domain ids, names, and timestamp when that domain was master:

   psql <dbname> -U <username> -c 'select id, storage_name,
     last_time_used_as_master from storage_domain_static'

(where of course <dbname> and <username> are the properties you set up 
during your initial engine installation.)
