Name

Assemble mode

Synopsis

mdadm --assemble mddevice [options] memberdevices

Assemble mode activates an array that has already been created using --create or --build. It might be helpful to think of Assemble mode as being similar to the raidstart command.

Options

-A, --assemble

Assembles (starts) an existing array.

-u, --uuid=

Specifies the UUID of an array to assemble. Disks are scanned for a RAID superblock containing the UUID and combined into an array.

-m, --super-minor=

Uses the minor number to identify which member disks belong to an array. All software arrays have a major number of 9. By default, each array has a minor number that corresponds to the number of its device special name. Thus, /dev/md1 has a minor number of 1, and /dev/md22 has a minor number of 22.
