Hi,

I'm having all kinds of problems trying to get a RAID1 + LVM partitioning scheme working on SL10.0. I'm wanting this:

/dev/sda: swap auto raid1a 100MB raid2a 100MB raid3a 100MB raid4a max

/dev/sdb: swap auto raid1b 100MB raid2b 100MB raid3b 100MB raid4b max

RAID: md0: raid1a + raid1b, /boot md1: raid2a + raid2b, /boot2 md2: raid3a + raid3b, /boot3 md3: raid4a + raid4b, LVM physical volume

LVM: volume group /dev/system: /dev/md3 logical volumes: / ext3 5GB /data ext3 200GB

i.e. an LVM physical volume on a RAID1 partition.

The partitioning fragment of my autoyast config looks like this:

<partitioning config:type="list"> <drive> <device>/dev/sda</device> <initialize config:type="boolean">false</initialize> <partitions config:type="list"> <partition> <filesystem config:type="symbol">swap</filesystem> <format config:type="boolean">true</format> <mount>swap</mount> <size>auto</size> </partition> <partition> 253 /dev/md0 <size>100mb</size> </partition> <partition> 253 /dev/md1 <size>100mb</size> </partition> <partition> 253 /dev/md2 <size>100mb</size> </partition> <partition> 253 /dev/md3 <size>max</size> </partition> </partitions> <use>all</use> </drive> <drive> <device>/dev/sdb</device> <initialize config:type="boolean">false</initialize> <partitions config:type="list"> <partition> <filesystem config:type="symbol">swap</filesystem> <format config:type="boolean">true</format> <mount>swap</mount> <size>auto</size> </partition> <partition> 253 /dev/md0 <size>100mb</size> </partition> <partition> 253 /dev/md1 <size>100mb</size> </partition> <partition> 253 /dev/md2 <size>100mb</size> </partition> <partition> 253 /dev/md3 <size>max</size> </partition> </partitions> <use>all</use> </drive> <drive> <device>/dev/md</device> <partitions config:type="list"> <partition> <filesystem config:type="symbol">ext3</filesystem> <format config:type="boolean">true</format> 130 0 <mount>/boot</mount> 4 left-asymmetric raid1 </partition> <partition> <filesystem config:type="symbol">ext3</filesystem> <format config:type="boolean">true</format> 130 1 <mount>/boot2</mount> 4 left-asymmetric raid1 </partition> <partition> <filesystem config:type="symbol">ext3</filesystem> <format config:type="boolean">true</format> 130 2 <mount>/boot3</mount> 4 left-asymmetric raid1 </partition> <partition> system 142 3 4 left-asymmetric raid1 </partition> </partitions> <use>all</use> </drive> <drive> <device>/dev/system</device> true <partitions config:type="list"> <partition> <filesystem config:type="symbol">ext3</filesystem> <format config:type="boolean">true</format> root1 <mount>/</mount> <size>5gb</size> </partition> <partition> <filesystem config:type="symbol">ext3</filesystem> <format config:type="boolean">true</format> data <mount>/data</mount> <size>200gb</size> </partition> </partitions> <pesize>32M</pesize> <use>all</use> </drive> </partitioning>

This validates against the DTDs with xmllint, and it _almost_ works under autoyast. Here's the Partitioning confirmation output:

Create extended partition /dev/sda1 (232.8 GB) Create swap partition /dev/sda5 (1.0 GB) Create partition /dev/sda6 (101.9 MB) with id=8E Create partition /dev/sda7 (101.9 MB) with id=8E Create partition /dev/sda8 (101.9 MB) with id=8E Create partition /dev/sda9 (231.5 GB) with id=8E Create extended partition /dev/sdb1 (232.8 GB) Create swap partition /dev/sdb5 (1.0 GB) Create partition /dev/sdb6 (101.9 MB) with id=FD Create partition /dev/sdb7 (101.9 MB) with id=FD Create partition /dev/sdb8 (101.9 MB) with id=FD Create partition /dev/sdb9 (231.5 GB) with id=FD Create software RAID /dev/md0 (101.9 MB) for /boot with ext3 Create software RAID /dev/md1 (101.9 MB) for /boot2 with ext3 Create software RAID /dev/md2 (101.9 MB) for /boot3 with ext3 Create software RAID /dev/md3 (231.5 GB) Create volume group system Create logical volume /dev/system/data (200.0 GB) for /data with ext3 Create logical volume /dev/system/root1 (5.0 GB) for / with ext3

The problem is that somehow it comes up with the wrong partition type /dev/sda[6-9] partitions, making them LVM partitions (8E) instead of RAID partitions (FD), it's added all the /dev/sda partitions to the /dev/system volume group, and the raid partitions only contain the /dev/sdb members, and so raid volume creation fails.

Does this look like an error in my config somewhere, or a bug? If I correct these problems by hand, everything works.

In addition, if I try and initialise the drives I get even more bizarre problems - the /dev/sda partitions disappear altogther. I've been deleting the partition tables by hand to get it this far.

This is x86_64 on sata drives, in case that matters.

Thanks a lot for any clues/ideas. Been banging my head against this for a day and a half now ...

Yeah, I've been banging my head a while with this kind of thing too. I'm not sure of the exact problem in your xml, but I do have a similar setup using IDE disks, see below. This one works except for the booting. I have to boot rescue and manually get rid of "resume=/dev/md1" in my /boot/grub/menu.lst in order to get the system to boot. I'm working on that right now. In addition to the manual edits in rescue mode, I do the following: # grub ... grub> root (hd0,0) ... grub> setup (hd0) ... grub> root (hd1,0) ... grub> setup (hd1) ... grub> quit # However, I'm not sure (yet) that this is needed. BTW, they tell me that lilo is better to use for RAID1 boot, but I'm not convinced. On top of that, I got a patch from Uwe G. that solves a network installation issue I had with the setup I'm using. I'm not sure you will need it though. The error I got (at partitioning phase) was -6002. Let me know how it goes, I'm aiming at using S-ATA disks myself in the near future. Good luck /LarS PS.

that's a bug in SL10.0 I'll send you a patch for the installation source via eMail and if it works, I'll send that patch to the mailinglist too.

Finally got back to this today, and your patch works great - LVM over Raid1 installs beautifully now. Thanks a lot! Cheers, Gavin
