Greetings all.
I've hit this bug also.
I've also tried the patch from Anthony to no avail.
I've been trying to make a recipe for a PowerPC based IBM Machine.
keeping "/" from entering the LVM, because Debian (and other distros
too) have major bugs when "/" it's inside it (in this architecture). So
there's no point on making only a "/boot" partition that stays out of it.
I've made it work at last making these changes in
lib/partman/lib/auto-lvm.sh: (partman-auto-lvm UDEB)
17c17
echo "$scheme${NL}100 1000 -1 ext3 \$primary{ } method{ $method }"
---
echo "$scheme${NL}100 1000 -1 ext3 method{ $method }"
As we know, device mapper doesn't care if it's physical volume it's on a
primary or a logical partition. He is there only to activate it(/them).
I've also included in this test installation (made a couple of them,
successfully) a partman-base modified UDEB with anthony's patch (but, as
stated earlier, it's not making difference)
Thanks to anthony for keeping alive this bug, and for the proposed
patch, else i couldn't have solved it.
The recipe im using is below.
d-i partman-auto/expert_recipe string \
boot-root :: \
8 1 1 prep \
$primary{ } \
$bootable{ } \
method{ prep } \
. \
8192 10000 8192 ext3 \
$primary{ } \
method{ format } format{ } \
use_filesystem{ } filesystem{ ext3 } \
mountpoint{ / } \
. \
64 512 300% linux-swap \
$lvmok{ } \
method{ swap } format{ } \
. \
500 10000 -1 ext3 \
$lvmok{ } \
$defaultignore{ } \
method{ format } format{ } \
use_filesystem{ } filesystem{ ext3 } \
mountpoint{ /srv } \
.
Again. Thanks, and have a nice day.
