Environment

• VMware Cloud Director 10.x
• Object Storage Extension 3..x

Cause

• In the OSE server logs, the keeper passed through the quick validation and prepared to start OSE java service but the java service did not start.
• Java is not in the latest version.

 

Resolution

1. In OSE server, check if the directory /opt/vmware/voss/log does contains OSE java log files.
2. The rpm requires java on provider version 
3. To check the java version, run this in OSE server : java -version
4. Upgrade the java to the supported version and restart the service. Refer, Requirements for deploying VMware Cloud Director Object Storage Extension to a Linux machine
