Bug#516347: debian-installer: guided-with-lvm no longer allows multiple primary partition
Hi,
Looking closer at partman logs, I now doubt that this is a
partman-auto-lvm specific issue.
The disk size as seen by the installer is 10947133440 bytes
The initial preseeded recipe is :
96 128 128 ext3 $primary{ } $bootable { } method{ format } \
format{ } use_filesystem{ } filesystem{ ext3 }
mountpoint{ /boot } . \
100 1000 -1 ext3 $lvmok{ } method{ format } format{ } \
use_filesystem{ } filesystem{ ext3 } mountpoint{ / }
Which is transformed by expand_recipe into the following actual scheme
for creating the primary partitions :
128 0 128 ext3 $primary{ } $bootable { } method{ format } \
format{ } use_filesystem{ } filesystem{ ext3
} mountpoint{ /boot } . \
10819 96 -1 ext3 $primary{ } method{ lvm }
This scheme should fit on the disk (10819+128=10947 MiB)
But the partman log extract at the end of this post shows that :
1) when parted_server is asked to create a 128 MiB partition at the
beginning of the disk,
It creates a 131.6 MiB (131604480 bytes) partition beginning at
position 32256, and ending at 131604479.
2) parted_server is then asked to create a 10819 MiB primary partition
to hold the physical volume,
but starting at position 131604480, it can find enough space on the
disk and fails :
How can the gap between what is asked and what is performed by
parted_server be explained ?
- 131572224 B doesn't equal 128 MB, so an International System Units
vs binary Units mismatch doesn't seem to be involved.
- the disk size seems not to be involved either, as having tried a lvm
preseeded recipe on a 70 GB physical hard drive have given the same
result (will try tomorrow with bigger disks)
- is some overhead missing in the partition size calculation by expand_recipe ?
- should the scheme be recomputed with feedback from the parted_server
before creating following partitions ?
On Etch, the same recipe works because the default behavior is to
create the physical volume in a logical partition, using the entire
free space (position parameter set to "full").
Any thoughts/questions on the subject are welcome :
- directions to look further
- examples of lvm preseed recipe working with the lenny installer
- requests for precision or execution traces
Regards.
