Partman-Auto - Multi-Disk OR Use Existing Layout via Preseed
First, I have to say I love Debian. But I've been struggling with the
preseeding lately. First it was the keyboard layout, as the name has
changed a few times.
But that's been rectified. So, now I am trying to get partitioning right.
This was the recipe I tried:
d-i partman-auto/disk string /dev/sdb /dev/sda
d-i partman-auto/method string lvm
d-i partman-auto/choose_recipe select boot-root
d-i partman-auto/purge_lvm_from_device boolean true
d-i partman-auto-lvm/new_vg_name string sysvg
d-i partman-lvm/device_remove_lvm boolean true
d-i partman-lvm/device_remove_md boolean true
d-i partman-lvm/confirm_nooverwrite boolean true
d-i partman-lvm/confirm boolean true
d-i partman/confirm_write_new_label boolean true
d-i partman/confirm boolean true
d-i partman/default_filesystem string ext3
d-i partman/mount_style select uuid
#d-i partman/choose_partition \
# select Finish partitioning and write changes to disk
d-i partman-auto/expert_recipe string \
boot-root :: \
512 30720 512 ext3 \
$primary{ } $bootable{ } $lvmignore { } \
method{ format } format{ } \
filesystem{ ext3 } \
mountpoint{ /boot } \
. \
10000 10100 10734 ext3 \
$primary{ } $defaultignore{ } \
method{ lvm } device{ /dev/sdb } \
vg_name{ sysvg } \
. \
10000 21000 1000000000 ext3 \
$defaultignore{ } \
method{ lvm } device{ /dev/sdb } \
vg_name{ xen_vg } \
. \
2048 9000 2048 linux-swap \
$lvmok{ } method{ swap } format{ } \
in_vg{ sysvg } lv_name{ swap1 } \
. \
4096 10500 4096 ext3 \
$lvmok{ } method{ format } format{ } \
in_vg{ sysvg } lv_name{ root } \
filesystem{ ext3 } mountpoint{ / } \
. \
4063 8000 4065 ext3 \
$lvmok{ } method{ format } format{ } \
in_vg{ sysvg } lv_name{ var } \
filesystem{ ext3 } mountpoint{ /var } \
. \
This didn't quite do the right thing.
Desired layout:
/dev/sda - 512MB disk:
/dev/sda1 - /boot - 512MB
/dev/sdb - Rest of disk -
/dev/sdb1 - physical_volume for sysvg volume group ~ 10.7GB
/dev/sdb2 - pysical_volume for xen_vg volume group - Remaining amount of
disk
and the three LVs - root, var, swap, inside of sysvg
So, I can't seem to get this to work right. I tried to even just use
/dev/sdb alone, but I coulnd't get it to ignore /dev/sda, even when
partman/disk only says /dev/sdb.
The other (cheating to me, but doable) option is to use the
pre-partman-script to do the correct partitioning, and write a recipe to
simply use the correct partitions..but I don't see any documents on this.
Please, someone tell me this can be done correctly.
What's really upsetting is that this is the equivalent recipe in kickstart:
clearpart --all --drives=/dev/sda,/dev/sdb --initlabel
part /boot --fstype ext3 --size=510 --asprimary --ondisk=/dev/sda
part pv.01 --size=10240 --asprimary --ondisk=/dev/sdb
part pv.02 --size=1 --grow --asprimary --ondisk=/dev/sdb
volgroup sysvg pv.01 --pesize=32768
volgroup xen_vg pv.02 --pesize=32768
logvol / --vgname=sysvg --size=4096 --fstype ext3 --name=root
logvol swap --vgname=sysvg --size=2048 --fstype ext3 --name=swap1
logvol /var --vgname=sysvg --size=4064 --fstype ext3 --name=var
I understand this may come off as a bit combative, but that's not what
I'm after. :)
I'd just like to get this done. Without this, my exercises remain an
exercise only. :-(
