Kasten 8.0.4 is giving me the following error:

Refresh of retention of immutable backups in a repository failed
One or more errors were encountered while monitoring and refreshing the retention period for backups in an immutable backups repository. The affected repository location is of type S3, in the bucket "k10-kasten-dr" at the path "k10/f5abfab9-6f53-4ac5-a3ba-ce0efd1644c5/migration/f5abfab9-6f53-4ac5-a3ba-ce0efd1644c5/k10/repo/". The profile being used to access this repository is called "k10-kasten-dr" in the "kasten-io" namespace.

Has anyone seen this before? Is it a permissions issue?

I’m just hazarding a guess here, but is it possible that you have more than one Kasten server pointed at this bucket, or more than one repository pointed at it?

No - just one server/repository.

@virtualhobbit There could be multiple reasons why Kasten fails to refresh the retention of the immutable blobs/contents.

You might have a detailed error message inside a container called bloblifecyclemanager-svc colocated within the crypto-svc pod.

kubectl logs deploy/crypto-svc -c bloblifecyclemanager-svc -n kasten-io --tail 1000
