Hi,
I am running a Debian 10 with
root@nfsshares-a:~# dpkg -l | grep ganesha
ii nfs-ganesha 3.3-4 amd64
nfs-ganesha is a NFS server in User Space
ii nfs-ganesha-ceph:amd64 3.3-4 amd64
nfs-ganesha fsal ceph libraries
ii nfs-ganesha-rados-grace:amd64 3.3-4 amd64
nfs-ganesha ganesha-rados-grace program
and
root@nfsshares-a:~# dpkg -l | grep ceph
ii ceph-common 14.2.16-pve1 amd64 common
utilities to mount and interact with a ceph storage cluster
ii libcephfs2 14.2.16-pve1 amd64 Ceph
distributed file system client library
ii nfs-ganesha-ceph:amd64 3.3-4 amd64
nfs-ganesha fsal ceph libraries
ii python-ceph-argparse 14.2.16-pve1 all Python 2
utility libraries for Ceph CLI
ii python-cephfs 14.2.16-pve1 amd64 Python 2
libraries for the Ceph libcephfs library
The config looks like this:
root@nfsshares-a:~# grep '^[[:blank:]]*[^[:blank:]#;]' /etc/ganesha/ganesha.conf
NFS_CORE_PARAM
{
Enable_NLM = false;

The Export configuration is created on the ceph dashboard and looks like this:

I get the following error message:

When I remove
filesystem = "cephfs";
in export-1 it works.
I believe my dashboard does not work together with its version or configuration of the
libcephfs2 (both same source and version).
Or did I misconfigure something here?
Best regards and a healthy new year!
