SSRS is missing after failover to other node We have 2 node setup cluster, after a failover I can't see the reporting services, even the service it self is missing. 

I checked control panel program manager, SSRS is not installed, I open reporting service configuration manager when clicking Find, it can't find the server. Is there a way to retrieve that. 

There are active reports already running before the failover. 

Sorry I'm new in SSRS, I researched the web and can't find any solution.
Reporting services is not cluster-aware. If you want high-availability you need to set up a scale-out deployment where multiple Report servers share the same back-end database.

From the documentation: High availability in SQL Server Reporting Services


  A scale-out deployment provides a way to share a database. If one
  report server goes down, other servers in the same deployment will
  continue to work.
  
  Reporting Services is not cluster-aware. By itself, a scale-out
  deployment does not provide load balancing


So you would have needed to install SSRS on more than one machine and set it up like that before the failover happened.
