Configure RAID support

Caution

This feature is available as Technology Preview. Use such configuration for testing and evaluation purposes only. For the Technology Preview feature definition, refer to Technology Preview support scope.

You can configure support of the software-based Redundant Array of Independent Disks (RAID) using BareMetalHosProfile to set up an LVM or mdadm-based RAID level 1 (raid1). If required, you can further configure RAID in the same profile, for example, to install a cluster operating system onto a RAID device.

Caution

  • RAID configuration on already provisioned bare metal machines or on an existing cluster is not supported.

    To start using any kind of RAIDs, reprovisioning of machines with a new BaremetalHostProfile is required.

  • Mirantis supports only the raid1 type of RAID devices both for LVM and mdadm. The raid0 type for the mdadm RAID is also available to be on par with the LVM linear type.

  • Mirantis recommends having at least two physical disks for RAID to prevent unnecessary complexity.
