Re: LVM preseed install fails with partition error

I am using a preseed file on a physical server with the following requirement:

The 146gb disk need to be partitioned as 120gb '/' partition and 25gb 'swap' partition with lvm.

The install fails with the error "Description: Failed to partition the selected diskThis happened because the selected recipe does not contain any partition that can be created on LVM volumes."

The following lines from the preseed specific to disk configuration:

d-i partman-auto/disk string /dev/sda
d-i partman-auto/method string lvm
d-i partman-lvm/device_remove_lvm boolean true
d-i partman-lvm/device_remove_lvm_span boolean true

mountpoint{ / }

25000 20 25000 linux-swap \
$lvmok{ } lv_name{ swap_1 } \
method{ swap } format{ }

Is any other option needed in the preseed for this to work?

Cheers,

Hi Sandeep

I think you are missing a section to describe the LVM volume group you want to create. This one works for me:

100 1000 1000000000 ext3 \
$defaultignore{ } \
$primary{ } \
method{ lvm } \
device{ /dev/sda } \
vg_name{ systemlv } \
.

I think you also need to add

in_vg{ systemlv }

to all the logical volumes (partitions) you want to create. Obviously, you can change the name systemlv to what ever you want.

You may also want to add this to the disk partition definition:

d-i partman/choose_partition select Finish partitioning and write changes to disk

Good luck!

Hi Iain,

I made changes as below based on your inputs. However I see the same error. Perhaps I'm missing something too obvious. Is there a chance the old content is being read still even though the preseed file is updated with the changes?

It is a vm with 150gb disk.

To make sure I am doing it correctly and my understanding is right about the three values given below:

153600 100 153600 ext4 - Use the full 150gb disk and a priority # 100

120000 90 120000 ext4 \ - Use 120gb / partition with priority # 90

25000 80 25000 linux-swap \ - Use 25gb swap partition with priority # 80

d-i partman-auto/expert_recipe string i3 :: \

153600 100 153600 ext4 \

$defaultignore{ } \

$primary{ } \

method{ lvm } \

device{ /dev/sda } \

vg_name{ i3vg } \

120000 90 120000 ext4 \

$defaultignore{ }

$lvmok{ } lv_name{ root } in_vg{ i3vg } \

method{ format } format{ } \

use_filesystem{ } filesystem{ ext4 } \

mountpoint{ / }

25000 80 25000 linux-swap \

$lvmok{ } lv_name{ swap_1 } in_vg{ i3vg } \

method{ swap } format{ }

Instead of <<d-i partman/choose_partition select Finish partitioning and write changes to disk>>, the following works for me <<d-i partman/choose_partition select finish>>

Cheers,

Sandeep.
