Hello.

I setup manila with cephfs driver-CephFS NFS shares and I use NFS-Ganesha based “ceph nfs” service.

This is my configuration:

[DEFAULT]
debug = true
enabled_share_protocols = NFS,CIFS,CEPHFS
[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 = az1
cephfs_filesystem_name = cephfs

I can create a share but cannot set access rule for it and I encountered this error in manila-share.log:

One more thing, when I run openstack share export location list myshare I see

lab-control01:/volumes/_nogroup/5d49f7c6-27a0-43c3-931d-56486b8f3d51/fb094ad8-9200-4c93-b800-304178f51136

lab-control01 is my openstack controller, is it right because nfs service is on ceph cluster.

Thank you.
