Dynatrace-server.service unable to start

[KeanBoon]

I am trying to perform Dynatrace Managed migration. I have followed the steps using backup and restore a cluster. Everything works fine until Failed to start Dynatrace Server. I keep getting the error below:

Please advise on the error above. Appreciate your opinion on this. Thank you.

Hi @KeanBoon ,

This question might best be served as a Chat question on D1 or Support so that you can provide the entire relevant output, logs, and specific steps taken for installation. 

Cheers,

This specific line tells the Server process is running, however it hasn't complete the startup:

Sep 08 03:06:17 server.sh[272397]: Starting Server ... failed, it's running but not listening

In order to find out, you have to look into the server.log. Usually such situations occur when where's a connectivity issue with other nodes or a misconfigured operating system. As suggested, the fastest way to solve it - get in touch with us via Zendesk - visit Support Center - https://support.dynatrace.com/

Hi Pradeepboda,

I encountered the issue due to insufficient storage allocated at the disk when doing the migration to new server. The issue resolved when additional storage was allocated to the disk.

There was another time I encounter the similar issue where dynatrace-server.service unable to start at 3-node cluster. This was due to elasticsearch.service at node 2 unable to start, hence causing dynatrace-server.service unable to start at node 1. The issue resolved when the elasticsearch.service at node 2 able to start.
