Resizing a server
|

|
|
=================
|

|
|
|
||
|
|
As you are using your JupyterHub, you may find that you have a need to increase or decrease
|
||
|
|
the amount of resources allocated to your TLJH install. How resources can be reallocated
|
||
|
|
will depend on the server interface; consult the installation page for your provider for
|
||
|
|
more information.
|
||
|
|
|
||
|
|
However, once resources have been relocated, you must tell TLJH to make use of these resources,
|
||
|
|
and verify that the resources have become available.

Verifying a Resize
|
||
|
|
==================
|
||
|
|
|
||
|
|
#. You will need to tell the JupyterHub to make use of these new resources.
|
||
|
|
To accomplish this, you will follow the instructions in :ref:`topic/tljh-config`
|
||
|
|
to set memory limits and reload the hub. This can be completed using the terminal
|
||
|
|
in the JupyterHub. It can also be completed through the Digital Ocean console or terminal.
|
||
|
|
|
||
|
|
#. TLJH configuration options can be verified by viewing the tljh-config output.
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
sudo tljh-config show
|
||
|
|
|
||
|
|
|
||
|
|
#. If you have changed your memory availability successfully, this will be reflected
|
||
|
|
in the `nbresuse <https://github.com/yuvipanda/nbresuse>`_ extension in the upper-right
|
||
|
|
when you open a Jupyter notebook on the Hub.

|
#. If you have changed the number of cores, this can be verified at the command line.
|
||
|
|
``nproc`` displays the number of available cores, and should be equal to the
|
||
|
|
number of cores you selected in the "Resize Droplet" panel.
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
nproc --all
|
||
|
|
|
||
|
|
|
||
|
|
#. Disk space changes can be verified, as well. The ``df`` command shows how much disk
|
||
|
|
space is available. The ``-hT`` argument allows us to have this printed in a human readable
|
||
|
|
format, and condenses the output to show one storage volume.
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
df -hT /home
