Hey SuccessfulKoala55 Thank you for your answers I really appreciate it. As for elasticsearch it was indeed the index error that was created before. The reason for that is that I was trying to setup a backup for elasticsearch and mongodb using azurefiles. So the scenario is I'm using persistent volumes on k8s that are using azure file shares as storage. Then I can rebuild my cluster and use the exact same storage so that the data is persistent and I can restore my application from the last state. I noticed a while ago that when trying to setup clearml from scratch using the backup data, the apiserver failed on mongodb migrations. Now after the issues with elasticsearch I know it concerns also elasticsearch. Therefore my question is, is there any way to reinitialize clearml but using the back up data for the services? Thank you in advance
