+To configure different mount points for data and log directories, use symbolic links:
+
+1. Create a symbolic link for the data directory:
+
+    ```sh

 - Configure [cluster DNS]({{< relref "/operate/rs/networking/cluster-dns.md" >}}) so that cluster nodes can reach each other by DNS names.
 - By default, the installation process requires an internet connection to install dependencies and synchronize the operating system clock. To learn more, see [Offline installation]({{< relref "/operate/rs/installing-upgrading/install/offline-installation" >}}).
