[NFS-Ganesha-Support] Re: Many ceph clusters from one ganesha server (rgw)

Would be nice if this librgw multi tenant, could be back ported into luminous -----Original Message----- From: Daniel Gryniewicz [mailto:dang@redhat.com] Sent: 01 March 2019 14:33 To: support(a)lists.nfs-ganesha.org Subject: [NFS-Ganesha-Support] Re: Many ceph clusters from one ganesha server (rgw) On 2/28/19 1:10 PM, asmolik(a)cloudferro.com wrote: > 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.
