I made a partition to fill empty space. What's interesting it works
only if this partition is before PV:
2048 5 2048 ext3 \
$primary{ } $bootable{ } \
method{ format } format{ } \
use_filesystem{ } filesystem{ ext3 } \
mountpoint{ /boot } \
. \
2048 10000 1000000000 ext3 \
$primary{ } \
method{ keep } \
. \
51200 10 51200 ext3 \
$primary{ } \
method{ lvm } vg_name{ servervg } \
. \
When I change order to:
2048 5 2048 ext3 \
$primary{ } $bootable{ } \
method{ format } format{ } \
use_filesystem{ } filesystem{ ext3 } \
mountpoint{ /boot } \
. \
51200 10 51200 ext3 \
$primary{ } \
method{ lvm } vg_name{ servervg } \
. \
2048 10000 1000000000 ext3 \
$primary{ } \
method{ keep } \
. \
It uses last partition as PV...
Unfortunately there is similar problem with logical volumes. I have:
100% 1 100% linux-swap \
$lvmok{ } \
in_vg{ servervg } lv_name{ swap } \
method{ swap } format{ } \
. \
20480 10 20480 ext3 \
$lvmok{ } \
in_vg{ servervg } lv_name{ root } \
method{ format } format{ } \
use_filesystem{ } filesystem{ ext3 } \
mountpoint{ / } \
. \
2048 1000 1000000000 ext3 \
$lvmok{ } \
in_vg{ servervg } lv_name{ removeme } \
method{ keep } \
.
If root definition is first it creates LV which fills whole VG. If
something else is first, it says that LV can't be created (I don't
remember exact message).
I think I will try something like this:
