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

Redeploy a node
|
||||
===============
|
||||
|
||||
Redeploying a node refers to the process of changing the roles that are
|
||||
assigned to a node. For example, you want to redeploy some compute and storage
|
||||
nodes to be MongoDB nodes.
|
||||
|
||||
**To redeploy a node:**
|
||||
|
||||
#. Prepare your environment:
|
||||
|
||||
#. Live migrate instances from the compute nodes. For more information,
|
||||
see `Configure migrations <http://docs.openstack.org/admin-guide-cloud/compute-configuring-migrations.html>`_.
|
||||
#. Back up or copy information from the Operating System nodes being
|
||||
redeployed.
|
||||
|
||||
#. Log in to the Fuel web UI.
|
||||
#. In the :guilabel:`Nodes` tab, select the node(s) that you want to remove
|
||||
and click :guilabel:`Delete`.
|
||||
|
||||
The deployed node will be marked as :guilabel:`PENDING DELETION`.
|
||||
|
||||
#. In the :guilabel:`Dashboard` tab, click :guilabel:`Deploy Changes`.
|
||||
|
||||
#. Wait for the node to become available in the list of :guilabel:`Discovered`
|
||||
nodes in the :guilabel:`Nodes` tab.
|
||||
#. Assign a new role to the node being redeployed.
|
||||
#. Adjust the settings of your environment as required.
|
||||
#. In the :guilabel:`Dashboard` tab, click :guilabel:`Deploy Changes`.
|
||||
#. Wait for the environment to be redeployed.
|
||||
|
||||
.. caution:: After redeploying an Operating System node, you will have to
|
||||
manually apply any configuration changes you made and reinstall the software
|
||||
that was running on the node or restore the system from the backup you made
|
||||
before redeploying the node.

Remove a node
|

=============
|
||||
|
||||
You may need to remove a node from your environment to replace
|
||||
hardware, repair an error, complete maintenance operations, and so on.
|
||||
|
||||
**To remove a node:**
|
||||
|
||||
#. Log in to the Fuel web UI.
|
||||
#. In the :guilabel:`Nodes` tab, select the node that you want to remove and
|
||||
click :guilabel:`Delete`.
|
||||
|
||||
The deployed node will be marked as :guilabel:`PENDING DELETION` and will

be removed from the environment after redeployment.
|
||||
#. Adjust the settings of your environment as required.
|
||||
#. In the :guilabel:`Dashboard` tab, click :guilabel:`Deploy Changes`.
|
||||
|
||||
Puppet removes the node from the configuration files and
|
||||
re-triggers corresponding services.
