Fixed In Version: openstack-cinder-11.1.0-10.el7ost
Doc Type: Bug Fix
Doc Text:
The Cinder Backup service's NFS backend assumed that the NFS server has been configured to allow the Backup service to create files and directories on the server. The Backup service runs as a non-privileged 'cinder' user, and this requires file permissions and ownership on the server be set correctly. This caused backups to fail if the NFS server wasn't configured to allow the 'cinder' user to create files and directories. With this update, when initializing the NFS backend, the Backup service checks whether the server's permissions and directory ownership are correct. The permissions and directory ownership are updated automatically to ensure the Backup service works correctly.
