Suggetion for the Installer

[inukaze]

Hi there, few moments ago i delete my partition table because i wanna make a new schema for partition like :

/dev/sda1 (Type 83 : Linux) -> for boot with 2 GiB i set boot flag
/dev/sda2 (Type 8e : LVM) -> for LVM with the rest of the free space available.

i had use cfdisk for make that partitions. and i wrote the changes.
on a root user terminal :

i create the physical volume with :

Code: Select all

pvcreate /dev/sda2

Physical volume "/dev/sda2" successfully created.

i create the group volume with :

Code: Select all

vgcreate Lignux /dev/sda2

Volume group "Lignux" successfully created

i create the logical volumes with :

Code: Select all

lvcreate -L 40G -n lv_64bits Lignux

Logical volume "lv_64bits" created.

lv_64bits Lignux for Salix 64 Bits

Code: Select all

lvcreate -L 30G -n lv_32bits Lignux

Logical volume "lv_32bits" created.

lv_32bits Lignux for Salix 32 Bits

Code: Select all

lvcreate -L 2G -n lv_intc Lignux

Logical volume "lv_intc" created.

lvcreate -L 2G -n lv_intc Lignux for Swap

Logical volume "lv_hogar" created.

Code: Select all

lvcreate -l 100%FREE -n lv_hogar Lignux

lv_hogar Lignux for my home partition.

i format my partition with:

Code: Select all

mkfs.ext4 -O ^has_journal -E discard /dev/Lignux/lv_64bits

Well after that i try to install Salix (32 Bits) but from the USB for some unknow reason for me, the partition /dev/sdg3 can't access to the ISO file for continue with the installation, well i after copy the same file to another pendrive partition for test

After i try to install Salix Live Xfce (64 Bits), but i can't see options for install on LVM partitions, and i don't know if the Live version came with some textual installer compatible with LVM.



Well the suggetions are :
1 - For the Live Versions, put a initrd capable to run ISO from GRUB2.
2 - For the Live Installer, add the support for LVM partitions.

Code: Select all

umount /mnt/dev

Code: Select all

umount /mnt/boot

Code: Select all

umount /mnt/home

Code: Select all

cd /

Code: Select all

umount /mnt

[inukaze]

Well, after a previous restart I noticed two critical missing points:

1 - In the initrd, /sbin/lvm did not exist because mkinitrd was originally executed inside the chroot before the LVM tools were fully available or indexed there, resulting in a stripped-down 48,490-block image without the binary.
2 - I forgot to copy the vmlinuz file to the right physical boot partition.

So, I wrote the entire procedure again from scratch with the proper fixes, installing manually much like doing a Gentoo installation from a Stage 3 tarball.

First, create the mount points needed for the manual installation:

Code: Select all

mkdir -p /mnt/home

Code: Select all

mkdir -p /mnt/boot

Now, mount the target root filesystem and target partitions from the Live Environment:

Code: Select all

mount /dev/Lignux/lv_64bits /mnt

Code: Select all

mount /dev/Lignux/lv_hogar /mnt/home

Code: Select all

mount /dev/sda1 /mnt/boot

Verify the free space and layout on the disks:

Code: Select all

df -h

Code: Select all

Copy the running filesystem from the Live Environment to our target SSD:

Code: Select all

rsync -aHAX /bin /sbin /usr /etc /lib /lib64 /var /opt /root /mnt/

Set the correct sticky bit permissions for our new /tmp directory:

Code: Select all

chmod 1777 /mnt/tmp

Determine the right kernel version variable from the active Live environment:

Code: Select all

KERNEL_VERSION=$(ls /lib/modules)

Code: Select all

Copy the vmlinuz file directly to our dedicated physical boot partition (/dev/sda1 mapped at /mnt/boot):

Code: Select all

cp /boot/vmlinuz /mnt/boot/vmlinuz-$KERNEL_VERSION

We need to generate the initrd.gz WITH LVM support. Since the chroot environment doesn't have the LVM binaries indexed yet, we generate it from the Live environment (where LVM is active and fully functional) pointing to our target directory using the -d switch:

Code: Select all

mkinitrd -c -k $KERNEL_VERSION -m lvm -f ext4 -r /dev/Lignux/lv_64bits -L -d /mnt

Code: Select all

59120 bloques
/boot/initrd.gz created.
Be sure to run lilo again if you use it.

Now we prepare the virtual filesystems and enter the chroot jail safely:

Code: Select all

mount --bind /dev /mnt/dev
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
chroot /mnt /bin/bash

Write the filesystem table (/etc/fstab) cleanly using a Here-Doc block:
