k10 DR backup fails with error: Unable to lock repo artifact


k10 DR backup fails in phase: Snapshotting Application Components

error messages:

Job failed to be executed
 Unable to lock repo artifact
 Error while attempting to acquire lock
 resource conflict

 

It was working previously, I’ve updated to the latest version 7.5.8.
Data is copied to the Disaster Recovery Target (Minio S3).

Backups of applications with  Snapshot Exports are working (tough to different bucket)

 

Can anybody help me to troubleshoot?

Thank you in advance.

@daniva Thank you for creating this topic.

Based on the error message, it seems to be caused by a lock for the particular storage repository.

Ideally these locks are created during repository maintenance and are cleaned up after the background maintenance completes. However, for some reason these locks are left out in your env, maybe due to non-graceful termination of the maintenance. 

You can find the lock by looking at the configmaps in Kasten namespace.

The name of the configmap would be k10-nslock.kopia-dr-repository-xxxxxxxxx 

Once you delete the configmap, Things should progress without any issues.
