mdadm --zero-superblock fails on md raid
sles10, x86_64. desired setup : disks 1 & 2 each have 2 partitions mirrored, resulting in two md devices (md0 raw raid 1 and md1 with lvm vg on top of it); disks 3-5 are in raid5 with single lvm vg on top of it. this setup can be easily achieved during manual setup and works nicely. attempting to do that during autoinstallation fails, using a profile generated from the system, previously installed manually. yast complains that "A logical volume with the requested size could not be created." during partition plan creation step 3 times, then fails with -4004 error during actual creation step. looking at y2log, i found some weird output : first, everything seem fine - INFO libstorage(3297) - SystemCmd.cc(addLine):625 Adding Line 1 " 1 logical volume(s) in volume group "data" now active" INFO libstorage(3297) - SystemCmd.cc(addLine):625 Adding Line 2 " 3 logical volume(s) in volume group "system" now active" later, two vgs are succesfully added and have correct sizes : INFO libstorage(3297) - SystemCmd.cc(addLine):625 Adding Line 1 " "data" 273.43 GB [273.40 GB used / 24.00 MB free]" INFO libstorage(3297) - SystemCmd.cc(addLine):625 Adding Line 2 " "system" 33.86 GB [33.80 GB used / 56.00 MB free]" then, at some point, yast has problems accessing md1, recreates it and decides to grab first lvm vg space (md1, system) for second vg (data, supposed to use md2 only) : INFO libstorage(6082) - MdCo.cc(getMdData):163 mdstat line:md1 : active raid1 cciss/c0d1p2[1] cciss/c0d0p2[0] INFO libstorage(6082) - LvmVg.cc(doCreatePv):1261 dev:/dev/md1 INFO libstorage(6082) - SystemCmd.cc(execute):160 SystemCmd Executing:"mdadm --zero-superblock /dev/md1" INFO libstorage(6082) - SystemCmd.cc(addLine):625 Adding Line 1 "mdadm: Unrecognised md component device - /dev/md1" INFO libstorage(6082) - SystemCmd.cc(logOutput):636 stderr:mdadm: Unrecognised md component device - /dev/md1 ...

I currently have sles10 set up to support x86 (i586) processors. Now I need to configure the repository to support X86_64 and IA64 architectures, in addition to my x86 processors. Does anyone have any recommendations to set up a single repository for all 3 architectures, or do they need to be kept separate? Also, since I'm new to the other 2 architectures this is probably a stupid question, but is it possible to use the same boot image to install all 3, or do they each need a different boot image (CD or PXE, preferrably CD)?

Did you try to use the driverupdate for SLES10 from ftp://ftp.suse.com/pub/people/ug/autoyast/ There was a bug with multiple LVM groups. But I can't say if that driverupdate solves your problem or if there is another problem with RAID too. -- ciao, Uwe Gansert Uwe Gansert, Server Technologies Team SUSE LINUX Products GmbH, Maxfeldstrasse 5, D-90409 Nuernberg, Germany Business: http://www.suse.de/~ug now playing Diary Of Dreams - Giftraum

the driverupdate has fixed the problem. thanks. btw, are updates like these (concerning autoyast) announced somewhere in an uniform way ? :)

it's always a good idea to keep an eye on this list for that. Sometimes I announce stuff like that here or mention it at least in a thread. Reading the changes files on www.suse.de/~ug is always good too. -- ciao, Uwe Gansert Uwe Gansert, Server Technologies Team SUSE LINUX Products GmbH, Maxfeldstrasse 5, D-90409 Nuernberg, Germany Business: http://www.suse.de/~ug now playing :Wumpscut: - Dying Culture [Second Movement]
