Rook is an open-source cloud-native storage orchestrator for Kubernetes that provides a framework to run Ceph storage systems. Ceph is a distributed storage system that provides object, block, and file storage in a unified system. Rook automates the deployment, bootstrapping, configuration, scaling, upgrading, and management of Ceph clusters.
When attempting to delete an RBD (RADOS Block Device) image, users may encounter an error indicating that the deletion has failed. This error is often accompanied by messages related to insufficient resources or misconfiguration within the Ceph cluster.
The RBD_IMAGE_DELETION_FAILED error occurs when the Ceph cluster is unable to process the deletion request for an RBD image. This can be due to a lack of available resources such as CPU, memory, or storage, or due to incorrect configuration settings that prevent the operation from completing successfully.
Ensure that the Ceph cluster has adequate resources. Check the resource allocation and usage using the following commands:
kubectl top nodes
kubectl top pods -n rook-ceph
Adjust the resource limits and requests in the Ceph cluster configuration if necessary.
Review the Ceph configuration settings to ensure they are correct. You can inspect the Ceph configuration by running:
ceph config dump
Look for any misconfigurations or incorrect parameters that might affect RBD operations.
Ensure that all Ceph components can communicate with each other. Check network connectivity and resolve any issues that might be causing disruptions.
