+
+.. versionchanged:: 3.7.3
+    GlusterFS versions prior to version **3.7.3** requires the following
+    additional steps to allow non-root users to mount the volume over libgfapi.
+    Following these steps is not required for recent versions i.e >= 3.7.3

+Further, use `chown` and/or `chmod` commands to change permissions on mount
+point or required directories to allow non-root access to appropriate users.
+
+If you do not provide a custom location for log file, you might see an error
+similar to the following during mount.
+
+.. code-block:: python
+
+   LibgfapiException: glfs_set_logging(None, 7) failed: Permission denied
+
+In such case, provide a log file path that has appropriate write permissions
+or change permission of default log location i.e `/var/log/glusterfs` or
+`/usr/local/var/log/glusterfs` accordingly.
