I've setup and tested a highly-available Ganesha cluster using focal-
proposed:

# apt-cache policy nfs-ganesha
nfs-ganesha:
  Installed: 3.0.3-0ubuntu3.2
  Candidate: 3.0.3-0ubuntu3.2
  Version table:
 *** 3.0.3-0ubuntu3.2 500
        500 http://archive.ubuntu.com/ubuntu focal-proposed/main amd64 Packages
        100 /var/lib/dpkg/status
     3.0.3-0ubuntu3.1 500
        500 http://nova.clouds.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages
     3.0.3-0ubuntu3 500
        500 http://nova.clouds.archive.ubuntu.com/ubuntu focal/main amd64 Packages

And have confirmed that the ganesha-rados-grace binary functions as
expected:

# ganesha-rados-grace --userid ceph-nfs --pool ceph-nfs dump
cur=4 rec=0

Title:
  nfs-ganesha doesn't ship the ganesha-rados-grace binary target in
  Focal

Status in nfs-ganesha package in Ubuntu:
  Fix Released
Status in nfs-ganesha source package in Focal:
  Fix Committed

Bug description:
  While the source is all present, the debian/control file doesn't build
  the binary package for ganesha-rados-grace.

  [Impact]

  It is impossible to setup HA Ganesha with Ceph as a backed on Focal.
  The correct way to setup the rados cluster backend for Ganesha is to
  use:

    ganesha-rados-grace add `hostname`

  to add the named host to the cluster, which will allow all units to
  share cluster state.

  [Test Plan]

  A new charm has been developed that configures nfs-ganesha
  (https://github.com/chrismacnaughton/charm-ceph-nfs) and will be used
  to verify that the cluster setup works correctly. it also functionally
  validates that shares are created correctly and are accessible.

  [Where problems could occur]

  Problems could occur around the binary target being fairly new in this
  release; however, the only change required is enabling that new binary
  target which is included in the version shipped in Focal.

  After verification has been confirmed, we can be fairly confident that
  the new binary target works as expected and doesn't interract badly
  with other parts.
