Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set covers all product layers, including MOSK management (formerly MCC). This means everything you need is in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Configure RAID support

TechPreview

During a management or MOSK cluster creation, you can configure the support of the software-based Redundant Array of Independent Disks (RAID) using BareMetalHosProfile to set up an LVM-based RAID level 1 (raid1) or an mdadm-based RAID level 0, 1, or 10 (raid0, raid1, or raid10).

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 the raid1 type of RAID devices both for LVM and mdadm.

  • Mirantis supports the raid0 type for the mdadm RAID to be on par with the LVM linear type.

  • Mirantis recommends having at least two physical disks for raid0 and raid1 devices to prevent unnecessary complexity.

  • Mirantis supports the raid10 type for mdadm RAID. At least four physical disks are required for this type of RAID.

  • Only an even number of disks can be used for a raid1 or raid10 device.
