- Addition of bricks dynamically to cold or hot tiers in a tiered volume is not supported.
- The following configuration changes are necessary for qemu and samba integration with libgfapi to work seamlessly:

    ~~~
    # gluster volume set <volname> server.allow-insecure on
    ~~~

    Edit `/etc/glusterfs/glusterd.vol` to contain this line: `option rpc-auth-allow-insecure on`

    Post 1, restarting the volume would be necessary:

    ~~~
    # gluster volume stop <volname>
    # gluster volume start <volname>
    ~~~

    Post 2, restarting glusterd would be necessary:

    ~~~
    # service glusterd restart
    ~~~

    or

    ~~~
    # systemctl restart glusterd
    ~~~
