Open Stack

Hi everyone,


I have deployed a OpenStack cluster with AIO mode by kolla-ansible.
In my globals.yml, something is enabled as followed:
    ......
    enable_ceph: "yes"
    enable_ceph_mds: "yes"
    enable_ceph_nfs: "yes"
    enable_manila: "yes"
    enable_manila_backend_cephfs_nfs: "yes"
    .......
And in my manila.conf, some configs are as followed:
    [DEFAULT]
    enabled_share_protocols = NFS,CIFS
    ......
    [cephfsnfs1]
    driver_handles_share_servers = False
    share_backend_name = CEPHFSNFS1
    share_driver = manila.share.drivers.cephfs.driver.CephFSDriver
    cephfs_protocol_helper_type = NFS
    cephfs_conf_path = /etc/ceph/ceph.conf
    cephfs_auth_id = manila
    cephfs_cluster_name = ceph
    cephfs_enable_snapshots = False
    cephfs_ganesha_server_is_remote = False
    cephfs_ganesha_server_ip = 172.16.60.84
    ......
I use CLI to create the nfs, some commands as followed:
    -> manila type-create cephfsnfstype false
    -> manila type-key cephfsnfstype set vendor_name=Ceph storage_protocol=NFS
    -> manila create --share-type cephfsnfstype --name cephnfsshare1 nfs 1
    -> manila share-export-location-list cephnfsshare1

    -> manila access-allow cephnfsshare1 ip 172.16.60.119
But I have got some error messages from /var/lib/docker/volumes/kolla_logs/_data/manila/manila-share.log

    I found some possible solutions[0][1][2][3] to try to fix this, but failed.
    Any suggestions?
