Feature #309157, revision 4
Title: Install and booting from partitioned MD devices

openSUSE-11.3: Unconfirmed
Priority
Requester: Important

Requested by: Dennis Olsson (dolsson)
Partner organization: openSUSE.org

Description:
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):
openSUSE.org: 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]").

Discussion:
#1: Dennis Olsson (dolsson) (2010-03-09 15:04:33)
This feature was created as a response to Bugzilla #585684.

#2: Dennis Olsson (dolsson) (2010-03-09 15:06:31)
Does this feature request have any connection with Feature #305883?
If yes, will the changes made for this feature for SLE 11 SP1 make it
into openSUSE 11.3?

+ #3: Arvin Schnell (aschnell) (2010-03-09 15:17:26) (reply to #2)
+ The code from feature #305883 is already included in openSUSE 11.3 but
+ you ask for more:
+ 1) Creation of RAIDs with partitions.
+ 2) Creation of RAIDs from whole disks instead of partitions.
