Hi, Alessandro
Currently, there's no way to address more than one ceph cluster in a
single Ganesha. The ceph configuration is in the global CEPH block,
which is a singleton, shared between all cephfs exports.
Typically, the way you would do this would be to run a ganesha server
per ceph cluster. This won't allow, however, putting all the exports
into a single pseudofs. This would be possible, by using redirects on
one server, but very complicated.
I'm not sure about the status of libcephfs allowing connections to
multiple servers. It may be possible, but there may be changes needed
to libcephfs to allow this in Ganesha. Once libcephfs allows it, it
shouldn't be too difficult to add config to the CEPH FSAL block within
an export.

Hi,
I'm trying to export several cephfs filesystems, hosted in different
clusters, using ganesha v2.5.3.
I saw from the code there is an option 'ceph_conf' that could be used to
specify different ceph configs, but it does not really appear to be an
option understood in the EXPORT block, probably it's only a general
config. Is there any way to export several cephfs filesystems, hosted in
different clusters, exposing them in appropriate pseudo paths?
Thanks,
Alessandro
