Hello,
Is it possible to connect ganesha and serve to clients more than one ceph cluster with
fsal_rgw? I can see that there is a global rgw config part with one ceph.conf in
ganesha.conf, so I guess it's not as simple as adding another fsal to the config, but
I'm wondering if it's at all possible - maybe with some changes to the code.
Is there maybe any other way to serve many rgw's so that they are visible as
mountpoint to the clients?

Hi, Aleksander.
Currently, no, it's not possible. As you noticed, Ganesha has a single
global config option for a ceph.conf, which means it can only connect to
a single cluster. In addition, FSAL_RGW currently has a singleton
instance of it's librgw connection. This is shared by all exports.
Finally, it looks like librgw (provided by Ceph) has the same issue: it
uses a singleton global context instance to connect to the cluster. So,
it looks like it would require quite a few code changes to both Ceph and
to Ganesha to be able to do this.
That said, it's fairly common to run a Ganesha instance on the same
machine as an RGW instance, so you can just run multiple Ganeshas. It
won't provide a single global namespace access to all the clusters, but
it will provide access.

Would be nice if this librgw multi tenant, could be back ported into
luminous

I'm not the librgw expert, but looking at the code (I'm looking at
Master), I don't see any multi-tenant for librgw. It looks like it can
only connect to a single cluster.
