Unable to start nodes + migrate.mv.db is locked

[alex-zel]

After installing nginx-agent and nginx-admin (on different machines) I'm unable to start an agent.

I've added a new agent and the "Test Setting" button verifies that everything is OK, however, when I go back to the main screen all I see is a blank screen with two messages:

1. No session selected yet
2. Welcome to Nginx Admin manager choose one of nginx agent node to start

Where do I select a session?
Where do I choose an nginx agent to start?
When I click the button to manage agent I get this message: "None nginx agent was configured yet, please configure one to start"
But I did configure an agent and the setting are OK.
Looking at the logs there is nothing useful.

I tried restarting the nginx-admin service and then I can't start it again (the only way I found was to restart the machine), looking at the logs I see:

Caused by: java.lang.IllegalStateException: The file is locked: nio:/opt/nginx-admin/database/migrate.mv.db [1.4.196/7]
...
Caused by: java.nio.channels.OverlappingFileLockException

I didn't change anything, followed the guide from README but it seems nothing really works.

thanks for report. after save your agent node on admin you must configure nginx settings to start use the node. edit your nginx agent , go to tab “configure nginx” and save settings. go to home, at this moment you will see your node to start a session. about lock file db can you send full log file ?

docs its not fully clear yet how to use and configure things (sorry about that) i’m opening another issue to improv docs , record some shorts videos installing and using the tool. improv restarts scripts too removings this locks if exists

Please let me know if you successfully connect with your node . Another question . Which operating system and version is being installed your admin and agent ?
