Re: cephfs set quota without mount

    Our ceph cluster is mainly used for openstack but we also need to
      provide storage to linux workstations via nfs and smb for our
      windows clients. Even though our linux workstations could talk to
      cephs directly we don't want them to be in our ceph public
      network. Ceph public network is only connected to openstack and
      ceph nodes. In addition we are implementing two gateway servers to
      export cephfs via nfs/smb using ctdb as HA

        I am just interested to know more about your use case for
          NFS as opposed to just using cephfs directly, and what are you
          using for HA?

        Hey folks,

          I use nfs-ganesha to export cephfs to nfs. nfs-ganesha can
          talk to 

          cephfs via libcephfs so there is no need for mounting cephfs
          manually. I 

          also like to use directory quotas from cephfs. Anyone knows a
          way to set 

          quota on directories without the need to mount it first?

          I was thinking about an admin socket, but the mds does not
          seem to offer 

          this functionality.
