Feature changed by: Dennis Olsson (DOlsson) Feature #309157, revision 2 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? -- openSUSE Feature: https://features.opensuse.org/309157

BTW, I have just tested openSUSE 11.3 Milestone 3. When I manually have created a partitioned MD RAID1 from 2 unpartitioned disks before starting the installation from DVD, I am able to make use of the partitioned MD device in YaST as a "normal" disk.  Although I can install on this MD device, it is not activated nor used after a reboot (see Bugzilla #586837). -- openSUSE Feature: https://features.opensuse.org/309157
