mdadm is a Linux utility used to manage and monitor software RAID devices.
R-Studio supports such devices and when drives from a mdadm RAID are connected to a Mac computer, it automatically detects them and assembles mdadm RAIDs accordingly.
R-Studio detects components from mdadm RAIDs and creates those RAIDs automatically. At the same time, R-Studio gives access to the components of those RAIDs (hard drives and images).
If recognized components of a mdadm RAID, including disk images, are added to R-Studio later, it automatically adds them to their respective mdadm RAID.
When an automatically created mdadm RAID is selected, R-Studio highlights its components. It also highlights the mdadm RAID that Linux may itself create from the same components.
R-Studio shows the components of the mdadm RAIDs on its LVM Components tab.
R-Studio shows broken mdadm RAIDs in pink.
The mdadm Components tab also allows you to manually disconnect or connect the components, for example, if they are such damaged that R-Studio cannot recognize them as parts of a broken mdadm RAID. Select the object from the drop-down box and click the Connect button. R-Studio displays the objects it recognizes as the components of the mdadm RAID in blue.
You may immediately switch to the mdadm RAID configuration that R-Studio believes most probable by clicking the Reassemble button.
R-Studio shows such mdadm RAIDs in blue:
