Hello, I use autoyast to perform installation of my SLES12SP5 and I met an issue : during the pre-script phasis, I use a script to make partitioning. In this, I ask to have 2 volume group : 1 for /var/log, /tmp and /home with a size of 1024/768/256MiB so, 2GiB. Second volume group is for /root with the rest of disk. For a 7GiB disk, I have this result : fdisk -l Disk /dev/sda: 7 GiB, 7516192768 bytes, 14680064 sectors Disk model: Virtual disk Units: sectors of 1 \* 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x00083158 Device Boot Start End Sectors Size Id Type /dev/sda1 \* 2048 1060863 1058816 517M 83 Linux /dev/sda2 1060864 2119679 1058816 517M 82 Linux swap / Solaris /dev/sda3 2119680 8402943 6283264 3G 8e Linux LVM /dev/sda4 8402944 14680063 6277120 3G 8e Linux LVM Disk /dev/mapper/vg\_root-lv\_root: 3 GiB, 3200253952 bytes, 6250496 sectors Units: sectors of 1 \* 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mapper/vg\_common-lv\_home: 256 MiB, 268435456 bytes, 524288 sectors Units: sectors of 1 \* 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mapper/vg\_common-lv\_logs: 1 GiB, 1073741824 bytes, 2097152 sectors Units: sectors of 1 \* 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mapper/vg\_common-lv\_tmp: 768 MiB, 805306368 bytes, 1572864 sectors Units: sectors of 1 \* 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes For lsblk: lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT fd0 2:0 1 4K 0 disk sda 8:0 0 7G 0 disk ??sda1 8:1 0 517M 0 part /boot ??sda2 8:2 0 517M 0 part [SWAP] ??sda3 8:3 0 3G 0 part ? ??vg\_root-lv\_root 254:0 0 3G 0 lvm / ??sda4 8:4 0 3G 0 part ??vg\_common-lv\_home 254:1 0 256M 0 lvm /home ??vg\_common-lv\_logs 254:2 0 1G 0 lvm /var/log ??vg\_common-lv\_tmp 254:3 0 768M 0 lvm /tmp So, my first volume group is set to 3GiB instead of 2… why ? What am I missing ? ---

@Frederic Hi, so what does the script do, size, sectors, blocks etc? Perhaps a calculation error (GiB vs GB?)? ---

@Frederic Hi can you upload to [https://susepaste.org/](https://susepaste.org/)? Or just post if not too long in the thread with markup quotes eg three of these “`”. ---

@Frederic Hi, strange indeed… I’m no autoyast user, but should size not have a suffix? `1024M+256M+768M` or `2G` instead of `1024+256+768` ---

I tried with a `2G` but nothing changes ---

@Frederic Hi, well the only thing I can think of is moving the vg\_root section to the last part of the file since it should process the rest of the disk (eg max)… ---

I tried to move the vg\_root section after the vg\_common, also change the `1024+256+768` by `2048M`, always the same result ☹ ---

@Frederic Hi, are you in a position to open a Support Request? If so, that may be the best route, something is not right in autoyast land… ☹ ---

maybe I was too tired yesterday evening but… with same VM, same autoyast xml file, I re-install the VM for saving some installation logs and it works this time ! I have my 2GiB vg\_common and 4GiB vg\_root…
