Draft patch to add this to RADOS_URLS follows. We'll still need to
update the docs but if you want to help test this, then that would be
good:
The config parses correctly when adding the namespace parameter to the
RADOS_URLS block. However it's unclear to me where the "url" config
option has to enabled, and how it should look like.
If I put below config option ganesha complains about syntax errors
%url rados://nfs-ganesha-27-fcal-ceph/ganesha.conf;
The config also parses correctly when the namespace parameter is added
to the CEPH_KV block. And the objects are added in the right namespace if one
is specified.
However, when the namespace parameter is included in the "CEPH" BLOCK
a warning is issued: Unknown parameter (namespace). This is true for the
"FSAL" block as well.
So I guess there needs to be done some more work to get the CEPH FSAL
recognize the namespace.
