Open Stack

Hi all,


I have met an issue when I use manila with cephfs nfs backend.


Environment Information:
- OS: ubuntu 18.04
- OpenStack Version: Train
- Kolla-ansible Version: 9.3.2


I used kolla-ansible to deploy my OpenStack environment AIO.


Here is the info of my globals.yml as followed:
---
kolla_base_distro: "ubuntu"
kolla_install_type: "source"
openstack_release: "train"
kolla_internal_vip_address: "172.16.150.67"
network_interface: "ens3"
neutron_external_interface: "ens4"
enable_haproxy: "no"
enable_ceph: "yes"
enable_ceph_mds: "yes"
enable_ceph_rgw: "yes"
enable_ceph_nfs: "yes"
enable_cinder: "yes"
enable_manila: "yes"
enable_manila_backend_cephfs_nfs: "yes"
enable_ceph_rgw_keystone: "yes"
ceph_osd_store_type: "filestore"


I try to use cephfs nfs backend for manila.
All containers are running and the services of manila is good.
