Configure disk partitioning

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.

Disk partition types
Type of partition Description
Base system Comprehensive of swap space, includes operating system and basic software option.
Virtual storage Storage for virtual instances.
Image storage Glance stores virtual instance images in this partition.
Cinder Storage allocated for Cinder.
Ceph and Ceph Journal Storage allocated for Ceph.
MongoDB Storage used for Ceilometer information stored in MongoDB.
MySQL Storage for Zabbix statistics.

To configure disk partitioning:

  1. In the Fuel web UI, click Nodes.

  2. Select a node or nodes.


    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.

  3. Click Disk Configuration.

  4. Click on a partition that you want to modify.

  5. In the Volume Groups, adjust the partition size using the slider.

  6. 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.

  7. Click Apply.
