Troubleshooting
Problem
When restarting a Virtual System Pattern Instance, the instance remains in LAUNCHING state and middleware perspective shows 0 roles.
CPU and Memory values for the Virtual Machine also report "unknown" values.
Cause
This problem symptom may occur for different reasons, but one situation which will cause this is compressed content (.gz) located under the /opt/IBM/maestro/agent/usr/servers/<Server_Name>/logs/ directory.
example:
/opt/IBM/maestro/agent/usr/servers/CustomNode.12342529101920/logs/trace.log.0.gz
IBM Cloud Pak System does not compress files located under this directory! Instead, a system or application administrator with access to the virtual machine might compress logs under the directory to try and free up or conserve disk space on the Virtual machine.
Compressing logs under IBM maestro agent directories is not supported and will prevent the IBM maestro agent from properly starting during a reboot of the Virtual Machine or restart of the Virtual System Pattern Instance.
Diagnosing The Problem
How to quickly check for compressed files..
syntax:
find /opt/IBM/maestro/agent/usr/servers/<Server_Name>/logs/ -name '*.gz'
find /opt/IBM/maestro/agent/usr/servers/<Server_Name>/logs/ -name '*.gz'
example:
find /opt/IBM/maestro/agent/usr/servers/CustomNode.12342529101920/logs/ -name '*.gz'
find /opt/IBM/maestro/agent/usr/servers/CustomNode.12342529101920/logs/ -name '*.gz'
The following error message will also be reported in the IBM maestro agent console log
/opt/IBM/maestro/agent/usr/servers/CustomNode.12342529101920/logs/console.log.0

Resolving The Problem
Uncompress the content and then restart the Virtual System Pattern Instance from the IBM Cloud Pak System UI
syntax:
gunzip -r /opt/IBM/maestro/agent/usr/servers/<Server_Name>/logs/
gunzip -r /opt/IBM/maestro/agent/usr/servers/<Server_Name>/logs/
example:
gunzip -r /opt/IBM/maestro/agent/usr/servers/CustomNode.12342529101920/logs/
