Configure disk partitioning
|
|
---------------------------
|
|
|
|
By default, Fuel allocates a balanced amount of disk space for
|
|
all components that will be installed on the corresponding node.
|
|
After you assign a role or roles to a node, you can modify the
|
|
disk partition as needed.
|
|
|
|
If you modify node roles, Fuel resets the disk partition to default settings.
|
|
|
|
The following table describes the partition types that you can configure
|
|
for each node.
|
|
|
|

**To configure disk partitioning:**
|
|
|
|
#. In the Fuel web UI, click :guilabel:`Nodes`.
|
|
#. Select a node or nodes.
|
|
|
|
.. note::
|
|
You can select multiple nodes of the same role. The nodes with
|
|
the same role must have identical hardware configuration. You cannot
|
|
change configuration of multiple nodes with different roles or hardware
|
|
in one transaction.
|
|
|
|
#. Click :guilabel:`Disk Configuration`.
|
|
#. Click on a partition that you want to modify.
|
|
#. In the :guilabel:`Volume Groups`, adjust the partition size using the
|
|
slider.
|
|
#. Alternatively, type the partition size in the corresponding field.
|
|
|
|
Fuel adjusts the number you type to satisfy block size boundary
|
|
requirements. The display adjusts to show the new allocation.
|
|
#. Click :guilabel:`Apply`.
