Feature changed by: Thomas Schmidt (digitaltomm) Feature #309157, revision 7 Title: Install and booting from partitioned MD devices - openSUSE.org: Unconfirmed - Priority - Requester: Important - openSUSE-11.3: Unconfirmed - Priority - Requester: Important openSUSE Distribution: 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. #4: Dennis Olsson (dolsson) (2010-03-10 00:07:10) (reply to #3) Yes, that is correct -- It would make life easier, when YaST would be able to do exactly this (so that the work-around described below would not be necessary). 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
