Verify machine registration observer: Unable to get machine information from configuration store

MHasan — Wed, 23 Dec 2020 12:32:14 GMT

Hello there

I have ArcGIS Enterprise 10.8.1 with base deployment and it was running properly.

Now when I open server manager it tells me to create a new site or join an existing one although I already have a site on this machine.

I have checked the arcgis server account permissions on file system and it has all the required permissions.

Here are the logs :

1-Verify machine registration observer: Disconnecting from site.

2-Verify machine registration observer: Unable to verify current machine information after retries.

3-Verify machine registration observer: Unable to get machine '****.GIS.****.LOCAL' information from configuration store, retrying.

4-Failed to get the configuration of the server machine '****.GIS.****.LOCAL'. Server machine '****.GIS.****.LOCAL' is not registered with the Site.

I hope you can help me with this issue.

Does the machine in question have multiple DNS aliases or hosts file modifications? If the startup of ArcGIS Server detected a name change and there wasn't a hostname.properties file defined I would expect similar entries in the logs. Just to confirm, is the site information (config-store and directories) on a local volume or a network share?

Thank you very much for response.

The machine has one DNS alias and the hosts file is not modified.

The site information (config-store and directories) is on a local volume.

Hi @MHasan,

The connection to the site files (config-store and directories) is controlled by the config-store-connection.xml file in the <Server_Install>\framework\etc directory. I assume this file is missing since you were returned to the 'Create New Site' page in Server Manager, the file will automatically be removed if the software loses access to the site files. You can copy the file from a working ArcGIS Server site and update the path with the correct location, then restart the service, but if there are underlying issues with the machine information those would need to be identified first.

Can you identify if the <machine_name>.json file in <config-store>\machines\ reflects the same name in the log entries?

I ran into the same issue at 10.9.0, and it was caused by the <machine_name>.json file getting blanked. I stopped the ArcGIS Server service, pasted in JSON from a healthy environment, updated the JSON for the correct environment, and started the ArcGIS Server service. I had to unregister and re-register the web adaptor, but everything's validating again. Thanks, @ChristopherPawlyszyn !

I know this is an old thread, but I also experienced this recently in my upgrade staging area. Same symptoms exactly, federated server disconnected itself from the site.

For the benefit of any visitors from Google, the log entries at the point of corruption showed:

Failed to get the configuration of the server machine '<machine_fqdn>'. Server machine '<machine_fqdn>' is not registered with the Site.

Verify machine registration observer: Unable to get machine '<machine_fqdn>' information from configuration store, retrying.

Verify machine registration observer: Unable to verify current machine information after retries.

Verify machine registration observer: Disconnecting from site.

The file machinename.json in \arcgisserver\config-store\machines was corrupted at some point, and showed a bunch of nul characters in text editor. Bringing back the same file from the live environment server and adjusting the machine name resolved my issue, and reconnected the server to my Portal.

In much the same scenario as @aorton_blueraster my Web Adaptor (IIS) for Server configuration on that machine was also wiped, and was resolved by re-running the /server/webadaptor config.

There is clearly some peculiar edge case causing this exact failure.
