Management cluster storage

The management cluster requires minimum two storage devices per node. Each device is used for different type of storage:

• The first device is always used for boot partitions and the root file system. SSD is recommended. A RAID device is not supported.

• One storage device per server is reserved for local persistent volumes. These volumes are served by the Local Storage Static Provisioner, that is local-volume-provisioner, and used by many services of MOSK.

You can configure host storage devices using BareMetalHostProfile resources. For details, see Create a custom bare metal host profile.
