Hi Uwe,

Doing automated installation of server with / on ext3 on software RAID 1 mirror of /dev/sda2 and /dev/sdb2 and /home on xfs on software RAID 10 of /dev/sda3, /dev/sdb3, /dev/sdc3, /dev/sdd3.

I want to preserve /home when doing an automated reinstall of the machine. I can keep the existing partitions fine and they get assigned to MD devices correctly.

However whilst the partitions are being kept fine, I see the messages "deleting MD device" (or some such wording), followed by "creating MD device" (or similar wording) and indeed it then fails to mount /home as the xfs file system is not there any more. )-:

If I set <create config:type="boolean">false</create> for the partitions on the /dev/md device in the autoyast file then the md devices are still destroyed but then not created again so the install fails immediately as there is nowhere to install. )-:

Is this a bug or a feature?

Is there any way I can get autoyast to preserve the existing md devices?

I now found time to fiddle around with this and has a closer look at autoyast code handling MD setup. Setup was mostly fine, except <use> in /dev/md part.

If you want to see my autoyast partitioning section, this is it:

Here you just need to have "<use>free</use>" Otherwise the code handles existing raids like existing partitions on a disk and prefers removal of exsiting raids over reusing them. So your setup is fine (except for <use> in /dev/md): - set "initialize" to false for every disk - set "create","format" to false for every partition belonging to a raid - set "initialize" to false for /dev/md - set "create" to false for every raid device in /dev/md to reuse - set "format" for /dev/md as prefered (e.g. false for /home, true for /) - set "<use>free</use>" for /dev/md entry in disks

Btw. the disks are gpt as they are 3TiB disks...

In tried with msdos while reproducing, but that should not matter...

PS. I am installing SLES 11 SP2 x86_64 if that matters.

I tried also with SLES 11 SP2...

Thanks a lot in advance!
