Package mdadm

The mdadm program controls Linux md devices (software RAID arrays)

The mdadm program is used to create, manage, and monitor Linux MD (software
RAID) devices. As such, it provides similar functionality to the raidtools
package. However, mdadm is a single program, and it can perform
almost all functions without a configuration file, though a configuration
file can be used to help with some common tasks.
