If a backend volume is deleted, DeleteVolume call for the same should succeed, detecting the image is missing and delete the related OMaps. This commit adds a test case to ensure this is occuring correctly. Updates #474 Signed-off-by: ShyamsundarR <srangana@redhat.com> (cherry picked from commit b93ed21fe8faa752d41ceb61c3025a67e27a056f)
Ceph CSI
This repo contains Ceph Container Storage Interface (CSI) driver for RBD, CephFS and kubernetes sidecar deployment yamls of provisioner, attacher, node-driver-registrar and snapshotter for supporting CSI functionalities.
Overview
Ceph CSI plugins implement an interface between CSI enabled Container Orchestrator (CO) and Ceph cluster. It allows dynamically provisioning Ceph volumes and attaching them to workloads.
Independent CSI plugins are provided to support RBD and CephFS backed volumes,
- For details about configuration and deployment of RBD plugin, please refer rbd doc and for CephFS plugin configuration and deployment please refer cephfs doc.
- For example usage of RBD and CephFS CSI plugins, see examples in
examples/.
NOTE:
- Ceph CSI
Arm64support is experimental.
Project status
Status: GA
Supported CO platforms
Ceph CSI drivers are currently developed and tested exclusively on Kubernetes environments. There is work in progress to make this CO independent and thus support other orchestration environments in the future.
NOTE:
csiv0.3is deprecated with release ofcsi v1.1.0
