Ambari not working on edge servers

[#1]

I'm not able to start/stop/restart services on edge servers (operations timeout). even tried to delete on of them from ambari but also not able to add it again since it hangs on the validation after registering the host as below. and error logs showing 23 Jun 2017 00:56:43,060 INFO [ambari-action-scheduler] ActionScheduler:838 - Removing command from queue, host=edge02001, commandId=261-0 23 Jun 2017 00:56:44,111 WARN [ambari-action-scheduler] ActionScheduler:811 - Host: edge02001, role: check_host, actionId: 261-0 expired and will be failed I'm using HDP 2.6

Please add the error that you see while starting the service.

Can you check if you have DB inconsistency ? You can try restarting ambari-server and see if it gives any warning/error with DB inconsistency.

Also try same with other browser, just to make sure its not browser specific issue.

Thanks for your help already solved, the problem was I don't see errors to know from where I should start.

Finally, the solution was, deleting the node from ambari then from the database hosts, hoststatus tables. then adding them again and all works fine without even loosing data 🙂
