It is just a test environment. I'm using Ceph FS is only because I want to integrate Ceph with all OpenStack environment. And a shared FS can let me do the live-migration but not just block-live-migration. I know Ceph FS is not production ready. So, the only suggestion is not to use it? Anymore?

The recommendation is to use RBD as a backend for OpenStack.
