.SH OVERVIEW
The 2.6.27 kernel brings the ability to support external metadata arrays.
External metadata formats, like DDF, differ from the native MD metadata
formats in that they define a set of disks and a series of sub-arrays
within those disks. MD metadata in comparison defines a 1:1
-relationship between a set of block devices and a raid array. For
-example to create 2 arrays at different raid levels on a single

+example to create 2 arrays at different RAID levels on a single
set of disks, MD metadata requires the disks be partitioned and then
each array can be created with a subset of those partitions. The
supported external formats perform this disk carving internally.
device to monitor. It can be a full path like /dev/md/container, or a
simple md device name like md127.
