12.04 preseeded install with RAID and LVM
I am trying to set up a preseed install (Ubuntu 12.04.03 64-bit) with the following partitioning recipe, but it's just not working and I'm not sure why.
Please, Obi-Wan, you're my only hope.
The -1 in the sizes were originally 1000000000 so I tried changing to -1 but it made no difference.

Here's the error I'm getting:
The disks are dual 50GiB (to be precise, 53,687,091,200 bytes).
Solution 1:
I think your mistake is here:
d-i partman-auto/choose_recipe select raid-lvm
d-i partman-auto/expert_recipe string \
raid-lvm :: \
You use partman-auto/choose_recipe when you are going to use a factory predefined recipe. If you are not, then make your own recipe using partman-auto/expert_recipe,specifying multiraid, not raid-lvm.
Your config file should be then
d-i partman-auto/expert_recipe string \
multiraid :: \
my conclusions came from reading this and this.
Solution 2:
I ended up here because I was getting the exact same errors:
Error: No recipe specified in partman-auto-raid/recipe
Along with:
Available disk space (XXX) too small for expert recipe (2200008705)
Here is the relevant bit of my BAD preseed file:
d-i partman-auto/method string raid
d-i partman-auto/disk string /dev/sda /dev/sdb
d-i partman-auto/expert_recipe string \
multiraid :: \
1 1 1 free \

# Last you need to specify how the previously defined partitions will be
# used in the RAID setup. Remember to use the correct partition numbers
# for logical partitions. RAID levels 0, 1, 5, 6 and 10 are supported;
# devices are separated using "#".
# Parameters are:
# <raidtype> <devcount> <sparecount> <fstype> <mountpoint> \
# <devices> <sparedevices>
d-i partman-auto-raid/recipe string 1 2 0 ext4 / /dev/sda2#/dev/sdb2 .
The problem, annoyingly enough was that I left a trailing backslash on the end of the last line of the expert recipe. It should have been this:
1 2000 -1 ext4 \
$gptonly{ } \
$primary{ } \
method{ format } format{ } \
use_filesystem{ } filesystem{ ext4 } \
.
Hope this helps somebody!
Solution 3:
You don't mention if you're using a 32- or 64-bit distribution here, but I thought that number reported in your error is pretty weird, "2200008705". Where would that come from? Well, take that number and subtract the largest value for a 32-bit unsigned int (2147483647), and you get 52,525,058, which looks an awful lot like the exact size of your 50GB disks, no?
Looking at section 5 of partman-auto-recipe.txt, which is about using very large sizes for whatever partition you want to fill all free space, it says:
Do not use higher than 1000000000 numbers because the shell arithmetic
is limited to 31 bits (on i386).
In your question, you said that before you set the values to -1, they were set to 10000000000, which is one place/zero too many when compared to their suggestion for a max value. Perhaps you overflowed a value somewhere, and that's why your recipe didn't initially work before you changed it to -1?
