I am trying to promote my datastore standby machine to primary for the tileCache datastore but it fails with the following error:
Server machine 'https://Machine1.domain.com:2443/arcgis/datastoreadmin/machines/Machine2.domain.com/makePrimary' returned an error. 'Attempt to make 'Machine2.domain.com' the primary data store machine with role 'PRIMARY' is not allowed.'
When I try with the relational datastore, it works.
Validating datastores on Admin REST API, returns both machines as healthy.
Any idea ?
