[Preseed] Partman expert recipe Error

[claude juif]

Hi,

I'm stuck with partman expert_recipe for 3 days now and it's driving me
crazy.

I've a 250GB hard drive and i try to use the following partition layout :

primary partition
512M /boot
4096M swap

LVM
10G /usr
20G /var
10G /
left free space to /home

so i use this recipe :


d-i       partman-auto/expert_recipe string boot-root ::
  512 513 512 ext3
  $primary{ }
  $bootable{ }
  method{ format }
  format{ }
  use_filesystem{ }
  filesystem{ ext4 }
  mountpoint{ '/boot' }
  .
  1024 1025 4096 linux-swap
  $primary{ }
  method{ swap }
  format{ }
  .
  1 10 -1 ext3
  $primary{ }
  method{ lvm }
  vg_name { debian }
  .
  10240 10241 10240 ext4
  $defaultignore{ }
  lv_name{ lv_usr }
  in_vg{ debian }
  method{ lvm }
  format{ }
  $lvmok{ }
  use_filesystem{ }
  filesystem{ ext4 }
  options/noatime{ noatime }
  mountpoint{ '/usr' }
  .
  20480 20481 20480 ext4
  $defaultignore{ }
  lv_name{ lv_var }
  in_vg{ debian }
  method{ lvm }
  format{ }
  $lvmok{ }
  use_filesystem{ }
  filesystem{ ext4 }
  options/noatime{ noatime }
  mountpoint{ '/var' }
  .
  10240 10241 10240 ext4
  $defaultignore{ }
  lv_name{ lv_root }
  in_vg{ debian }
  method{ lvm }
  format{ }
  $lvmok{ }
  use_filesystem{ }
  filesystem{ ext4 }
  options/noatime{ noatime }
  mountpoint{ '/' }
  .
  1 10 -1 ext4
  $defaultignore{ }
  lv_name{ lv_home }
  in_vg{ debian }
  method{ lvm }
  format{ }
  $lvmok{ }
  use_filesystem{ }
  filesystem{ ext4 }
  options/noatime{ noatime }
  mountpoint{ '/home' }


The only things i get is "Available disk space (250059) is too small for
expert recipe (15400000000).

This number 15400000000 is so huge. I think about a signed / unsigned error
in partman. I try to follow the size allocation formula to see if something
goes wrong but everything looks fine.

If someone can give me a hand on this, it would be greatly appreciated.

Regards,
