Feature #309157, revision 1
Title: Install and booting from partitioned MD devices

openSUSE-11.3: Unconfirmed
Requester: Important

Requested by: Dennis Olsson (dolsson)
Partner organization:

Now that the kernel 2.6 supports partitioned MD devices, even to the point
where it is possible create a MD device from unpartitioned disks , after which
the partitions are created on the MD device, YaST2 needs to be upgraded to be
able to handle partitioned MD devices , just as it should be possible to be
able to create partitioned MD devices consisting of unpartitioned disks .

Business case (Partner benefit): Using partitioned MD devices makes it a lot easier to create and
handle MD devices in that one needs a lot less MD devices. E.g. creating a
RAID1 using two disks require first to partitioned the disks (e.g. p1 for
"/boot", p2 for "swap" and p3 for LVM), mark these partitions as type "0xFD",
after which each of these 3 partitions can be put together as 3 x RAID1 MD
devices (/dev/md[0-3]). Using partitioned MD device makes this a lot easier by
creating the MD device out of the 2 unpartitioned disks having e.g.
"/dev/md/raid1" and then create the 3 partitions ("/dev/md/raid1p[1-3]").
