The first attempt to create a test backup of a Cinder volume on an NFS share fails with a permission denied error.
Attempting to verify the Cinder backup configuration results in a permission error when creating the initial backup.
VMware Integrated OpenStack does not have the correct permissions to write to the NFS share.
- Using SSH, log in to the controller node as the root user.
- Go to the mount directory for the Cinder backup configuration.
- Change the folder owner from
chown -R cinder:cinder *
This corrects the configuration and gives the Cinder component permission to access the NFS share.
