Re: gluster and nfs-ganesha

Hi Jiffin,

I looked at the document, and there are 2 things:

1. In Gluster 3.8 it seems you don't need to do that at all, it creates this automatically, so why not in 3.10?
2. The step by step guide, in the last item, doesn't say where exactly do I need to create the nfs-ganesha directory. The copy/paste seems irrelevant as enabling nfs-ganesha creates automatically the ganesha.conf and a subdirectory (called "exports") with the volume share configuration file.

Also, could someone tell me whats up with no ganesha on 3.12?

Thanks

                          I'm
                            using CentOS 7.4 with Gluster 3.10.7 and
                            Ganesha NFS 2.4.5.

                          I'm
                            trying to create a very simple 2 nodes
                            cluster to be used with NFS-ganesha. I've
                            created the bricks and the volume. Here's
                            the output:

                            enable - it creates a wrong symbolic link
                            and failes:

                            # gluster nfs-ganesha enable
                            Enabling NFS-Ganesha requires
                              Gluster-NFS to be disabled across the
                              trusted pool. Do you still want to
                              continue?

                              I've seen some reports (and fixed) in

                                Hat solutions (https://access.redhat.com/solutions/3099581)
                                but this doesn't help.

                              Suggestions?

    Hi,

    It seems you have not created directory nfs-ganesha under shared
    storage and plus copy/create ganesha.conf/ganesha-ha.conf inside

    Please follow this document
http://docs.gluster.org/en/latest/Administrator%20Guide/NFS-Ganesha%20GlusterFS%20Integration/

    Regards,

    Jiffin

                              I tried to upgrade to Gluster 3.12
                                and it seems Ganesha support was kicked
                                out? whats replacing it?
