While you are configuring the Cinder backup on an NFS share, the first attempt to create a test backup fails.

When you verify the Cinder backup configuration, you get an error when you create the initial backup.

VMware Integrated OpenStack does not have the correct permissions to write to the NFS share.

Procedure

  1. Using SSH, log in to the controller01 node as the root user.
  2. Go to the mount directory for the Cinder backup configuration.
    cd /var/lib/cinder/backup_mount/
  3. Change the folder owner from root to cinder.
    chown -R cinder:cinder *

Results

This workaround corrects the configuration and gives the Cinder component permission to access the NFS share.
