1.Repartition TrueNAS so XNAT has a slice

• [x] 10TB for XNAT
• [x] 0.5TB XNAT

2. Migrate XNAT data from Isilon to TrueNAS

   • [x] Mount new partitions on test VM
   • [ ] Migrate data

3. Get access to production database (still in ISG limbo)

   • [ ] Use dev-database for testing
   • [ ] Check firewall rules for dev
   • [ ] Apply dev rules to prod

4. Mount TrueNAS in the k8s cluster

   • [ ] Create a manifest for PV and PVC

5. HAProxy config for 8104

   • [ ] TCP service in the ingress configmap

6. Scanner communication to XNAT

7. Backup storage?

   • [ ] RSync to Isilon. Likely cronjob - hopefully in the cluster, if not in the test VM
   • [ ] New TrueNAS?

----- Nice to have

7. Add a probes

   • [ ] liveliness
   • [ ] readiness

8. Pull configuration from files

9. HA

High Availability: (Low priority)

• Sticky sessions - you manually have to do the re-do. This may not work for DICOM listener
• Separating XNAT's backend and frontend. Would be more robust, but it would take more effort

Auto Export

• User SLURM Rest API (hopefully) - to follow up on tickets
