Hello @RMarius ,

Based on the logs from the primer, I see you are running Kubernetes 1.23.

This version is not (yet) supported in K10: https://docs.kasten.io/latest/operating/support.html

We’re working on it though.

In the meantime I would advise to use a 1.22 K8s cluster.

Best regards,

Sylvain Huguet

@shuguet Thank you, I will reinstall the cluster with 1.22 and come back with feedback asap.

@shuguet any estimate when 1.23 support will be available? 1.22 will reach EOL on October ( https://kubernetes.io/releases/#release-v1-22 ) and people should have time for upgrades also.

@olljanat sorry I was out of the office.

Yes, we’re hard at work on this, shouldn’t be long now.

Best regards,

I Have same issue

@mcoulibaly I believe I have a different issue. It seems you're using NFS volumes/storageclass which is not supporting volumesnapshot

Please review veeam kasten official doc for more details on how to backup unsupported storageclass/volumes
