Here's quick detail about how to do what Michael Krysiak asked about: I did what you're asking about: convert (by copying) a non-LVM, 2 minidisk (/ and /usr) SLES9 31-bit to turn it into a SLES9 guest that has a non-LVM root-boot partition with the rest of its partitions and dasd given to LVM. (Everyone has rightly scared me out of putting the whole thing onto LVM because rescuing an all-LVM guest is much harder.)
You'll need to decide which directories you want in the non-LVM boot partition and its size (100MB worked ok for booting but we later changed it to 750MB so that YAST had enough space to install service packs)(Mark Post suggested having 2 non-LVM partitions "A relatively small non-LVM root partition. A separate, small non-LVM /boot partition" and you can do that if you modify my steps) Get the new boot mdisk/dasd online to your SLES9 guest; dasdfmt and fdasd the new boot mdisk/dasd; Make an ext3 filesystem on the new root-boot partition; Mount your new root-boot partition at /mnt mount -t ext3 /dev/dasdx1 /mnt For our purposes we put these directories into the new root-boot partition using command (thank you to an IBM redpiece-book about scsi and FCP): cp -r --no-dereference --preserve=all --target-directory=/mnt /bin /boot /dev /etc /lib /root /sbin /srv cd /mnt and mkdir the LVM mount points: mkdir usr var opt tmp home mkdir sys proc Give the other partitions/dev/dasdxn's to LVM, For example: pvcreate /dev/dasdh1 /dev/dasdj1 /dev/dasdk1 Then vgcreate vg1 /dev/dasdh1 /dev/dasdj1 /dev/dasdk1 to put them into a volume group; Then create the needed logical volumes for the missing directories (your sizes will be different from mine; I put everything on 1 mod-3 dasd); lvcreate -L 1200M -n usr vg1 Logical volume "usr" created lvcreate -L 256M -n var vg1 Logical volume "var" created lvcreate -L 184M -n opt vg1 Logical volume "opt" created lvcreate -L 200M -n tmp vg1 Logical volume "tmp" created lvcreate -L 44M -n home vg1 Logical volume "home" created lvcreate -L 128M -n swap1 vg1 (optional; probably controversial; your choice) Logical volume "swap1" created Make an ext3 filesystem on each non-swap LV Then mount the LV's at their corresponding /mnt/ points: Mount /dev/vg1/usr /mnt/usr Mount Etc etc etc etc Copy the /usr /var /opt /tmp/home filesystems or directories from old partitions to new LV's using cp (see above) or Mark Post's link to the tar method; To make the new boot partition bootable, Prep so mkinitrd and zipl will work in the chroot environment: mount -t sysfs sysfs /mnt/sys mount -t proc proc /mnt/proc chroot /mnt mkinitrd (here's my mkinitrd's output, 0.0.0209 is the new boot dev) Root device: /dev/dasda1 (mounted on / as ext3) Module list: jbd ext3 dasd_diag_mod dasd_fba_mod dasd_eckd_mod Kernel image: /boot/image-2.6.5-7.151-s390 Initrd image: /boot/initrd-2.6.5-7.151-s390 Shared libs: lib/ld-2.3.3.so lib/libc.so.6 lib/libselinux.so.1 Modules: kernel/fs/jbd/jbd.ko kernel/fs/ext3/ext3.ko kernel/drivers/s390/block/dasd_mod.ko kernel/drivers/s390/block/dasd_diag_mod.ko kernel/drivers/s390/block/dasd_fba_mod.ko kernel/drivers/s390/block/dasd_eckd_mod.ko DASDs: 0.0.0200(ECKD) 0.0.0201(ECKD) 0.0.0209(ECKD) zipl -V Use -V flag to see what zipl is doing (here's my zipl output; note Using config file '/etc/zipl.conf' Target device information Device..........................: 5e:08 Partition.......................: 5e:09 Device name.....................: dasdc DASD device number..............: 0209 Type............................: disk partition Disk layout.....................: ECKD/compatible disk layout Geometry - heads................: 15 Geometry - sectors..............: 12 Geometry - cylinders............: 3338 Geometry - start................: 24 File system block size..........: 4096 Physical block size.............: 4096 Device size in physical blocks..: 25596 Building bootmap '/boot/zipl/bootmap' Adding IPL section 'ipl' (default) kernel image......: /boot/image at 0x10000 kernel parmline...: 'root=/dev/dasda1 selinux=0 TERM=dumb elevator=cfq' at 0x1000 initial ramdisk...: /boot/initrd at 0x800000 Preparing boot device: dasdc (0209).

We aren't using logicial volumes. We would like to copy this installation to a logical volume with 9 dasd. What is the recommended way of doing this? Or is it necessary to do a new install?
