Hello All.
        Does anyone provides Ceph rbd/rgw/cephfs through NFS?  I have a requirement about Ceph Cluster which needs to provide NFS service.

We export a CephFS mount point on one of our NFS servers. Works out of the box with Ubuntu Trusty, a recent kernel and kernel-based cephfs driver.

ceph-fuse did not work that well, and using nfs-ganesha 2.2 instead of standard kernel based NFSd resulted in segfaults and permissions problems.

I've found that using knfsd does not preserve cephfs directory and file layouts, but using nfs-ganesha does. I'm currently using nfs-ganesha 2.4dev5 and seems stable so far.
