MS SQL Server & Atom Models hidden after restart

[jmdedalus]

Description

Last week, I imported some models into MDM and then shut the instance down for the weekend. Upon restarting the instance this morning, only the CSV-imported model is visible - the atomio & MS SQL Server imported models are hidden.

Steps to reproduce

e.g.

1. Deploy/launch new MDM instance
2. Using the Browse tab...
3. Create a new folder called, eg, ODS
4. Import a new model - this issue has been observed with the following model imports
   • MS SQL Server
   • Atomio FHIR
   • Atomio MDM (https://modelcatalogue.cs.ox.ac.uk/sandbox)
5. Confirm model is imported
6. Shutdown instance (eg kubectl scale --replicas=0 deployment mauro)
7. Resume instance
8. Notice that the ODS folder is not shown
9. Attempt to re-add ODS
10. Notice that MDM displays error "Property [label] with value [ODS] must be unique"
    
11. Create new folder ods
12. Notice that the new folder ods and the previously created folder ODS are now visibile, and the previously imported model is shown:
    

Note that you can (repeatedly) delete the ods folder and the ODS folder disappears, and recreate it and ODS reappears.

Expected behavior

The previously imported MS SQL Server (and atomio) model(s) should be displayed in the Browse tab.

Screenshots

• System resumed with only previously imported CSV model visible:
  
• Attempting to re-add ODS folder
  
• Create folder with the a different case:
  

Environment

• Mauro Version 7.3.0
• mdm-core 5.3.0

Additional context

Hi @jmdedalus, thanks for raising this. If this keeps occurring we'd definitely be interested to know, as it clearly shouldn't.

I'm not very familiar with Kubernetes, do you possibly know if the shutdown step does a clean shutdown of the Tomcat instances and database?
