Hello,
I have the same problem mentioned some times since 2002 in the list,
unfortunately I did not found an answer which works for me.
I am installing SLES8 through autoyast with software raid and LVM on it.
Software Raid contains two partitions (sda3 and sdb3) as I can not use
whole disks. The machine is a pSeries p690 LPAR so a PrepBoot partition is
required on each disk.
The installation worked fine for the first time, repeating the installation
on the same disks produced an error: can not create md0 device and can not
create system volume group- volume group already exists.
I am using <initialize config:type="boolean">true</initialize> in each
drive section
And true in lvmgroup.
I guess the problem is related to the persistent superblock used by
software raid and VGDA on the disk used by LVM. I also tried using a
prescript:
dd if=/dev/zero of=/dev/sda bs=1MB count=3
dd if=/dev/zero of=/dev/sdb bs=1MB count=3
# this does not works:
blockdev --rereadpt /dev/sda
blockdev --rereadpt /dev/sdb
For network boot on pSeries I am using SUSE SLES8 SP3 Kernel with the
builtin commandline: ./mkzimage_cmdline -a -1 -c -s "insmod=e100
insmod=e1000 hostip=9.156.175.22 netmask=255.255.255.0
install=nfs://9.156.175.8/software/Linux/PPC/SLES8/unpacked/CD1
autoyast=tftp://9.156.175.8/tftpboot/autoyast_tb.xml" install.tb
Unfortunately I can overwrite the begining of the disk, but rereading the
partition table fails (disc is in use message in the log). Is there any
trick how to reread the partition table or to get rid of the persistent
Superblock and VGDA before the installation starts? Now, I need to start
installation, read the error messages about raid and lvm, restart
installation and it works fine running second time. It also works fine on a
new LPAR.
Any help is welcome..
