HowTo: ANOPS: Install AV Linux 4.2 on usb disk drive

This is my ANOPS setup.

ANOPS is ANOther Portable Studio based on AV Linux.

Goal
===

- Portable usb hard disk installation
- Ability to install avl to other systems
- Create and restore system backups

NOTE:
1. All disk, partition and device file names are ONLY PLACEHOLDERS !!!
These are eg. /dev/sdg, /dev/sdg1, /dev/sdg2, ...
Also (hd0), (hd2), (hd0,4), (hd2,4), ..
Further WD1_P1_AVLL, WD1_P2_AVLR, wd1_p5_avl42, ...
Be shure you know at any time which are the right device names.

2. If you have multiple live boot partitions available to the system,
eg. boot cdroms and/or unetbooting partitions, it's likely that the wrong
image is loaded. (That's why /live is moved to /liveorg in "fix live boot".

3. After the installation, the system boots with grub to the AV Linux intallation.
If you delete/format this partition, you cannot boot the "Live" or "Restore" partitions anymore.
(You need another running system to toggle the boot flag to the "Live" or "Restore" partition to fix this.)

4. Backup the data and bkp partitions to a different drive if you want a full backup.

5. !!! <- these are important notes.

Prerequisites
==========

- a usb disk that can be completly whiped, all data will be lost !!!
- free USB 2.0 Port, no keyboard, mouse or usb audio device connected to this port (one port usually has several plugs)!
- running linux system as base
- gparted
- unetbootin
- avlinux4.2-liqx-lxde-i386-en.iso image

Installation steps
=============

- boot base linux
- prepare partitions and file systems on usb hard drive
- install avl42 live system with unetbootin on usb hard drive
- boot avl42 live from usb hard drive
- install avl42, no reboot
- fix grub installation
- fix boot flag
- boot avl from usb hard drive, add rt-kernel
- fix live boot
- create system backup
- make system backup restoreable
- restore system

Used base
========

- Tested on existing AVLinux 4.1 and AVLinux 4.2 installation

Used partitions
===========

- partition for live boot
- partition for restore boot, file exchange
- partition for swap
- partition for os
- partition for os backup
- partition for data

My hard disk setup:
usb drive size: 500.1 GB, Western Digital

Labels: HDName_PartitionNumber_Purpose
Usage Partition Size Type Label AVL live boot p1 4GB fat32 WD1_P1_AVLL AVL restore boot p2 32GB fat32 WD1_P2_AVLR swap p3 2GB swap extended partition p4 AVL 4.2 os p5 32GB ext3 wd1_p5_avl42 backup p6 32GB ext3 wd1_p6_bkp data p7 rest ext3 wd1_p7_data
boot base linux
============

Do it.

prepare partitions:
==============

Your disk will probably have a different name than /dev/sdg !!!

All data on disk will be lost.

Find usb disk
root terminal, find by size

Code:

fdisk -l

Disk /dev/sdg: 500.1 GB
or
menu -> system tools -> disk utility
-> wd elements -> device: /dev/sdg

umount all partitions of /dev/sdg

menu -> preferences -> gparted
select disks (upper right) (dev/sdg)
delete existing partitions
new partition: primary partition, filesystem fat32, new size (4*1024MiB) 4096MiB, Label WD1_P1_AVLL, add
new partition: primary partition, filesystem fat32, new size (32*1024MiB) 32768MiB, Label WD1_P2_AVLR, add
new partition: primary partition, filesystem linux swap, new size (2*1024Mib) 2048MiB, add
new partition: Extended Partition, add
new partition: Logical Partition, filesystem ext3, new size (32*1024MiB) 32768MiB, Label wd1_p5_avl42, add
new partition: Logical Partition, filesystem ext3, new size (32*1024MiB) 32768MiB, Label , wd1_p6_bkp add
new partition: Logical Partition, filesystem ext3, Label , wd1_p7_data add -> (362,76 GiB)

Apply All Operations
Close, Quit

install avl42 live system
==================

Unplug, replug usb drive / check with "mount" in terminal -> /dev/sdg1 on /media/WD1_P1_AVLL type vfat !!!

Menu -> System Tools -> UNetbootin

Select Diskimage
Select Image file -> /path/to/avlinux4.2-liqx-lxde-i386-en.iso
Type USB Drive, Drive /dev/sdg1
Ok
Exit

boot avl42 live from usb hard drive
==========================

Reboot, select to boot from usb drive while booting

install avl42
=========

Now in AVL42 live booted from usb disk.

check mount points in terminal: "mount" -> /dev/sdg* are the partitions (could change)!!!

Install AV Linux (Desktop)
continue, yes
continue, ok
select sdg, ok
quit (gparted)
select sdg3 for swap, ok
select sdg5 for root, ok
select root, put /home on the root partition, ok
root pw, ok, twice
user real name, ok
user name, ok
pw for user, ok, twice
hostname, ok
select grub installation: root, root partition !!!, ok
time zone
continue? yes
installation: root will be formated -> label gone.
reboot? -> No!!!

restore fs label
in root terminal
check label

Code:

e2label /dev/sdg5

set label

Code:

e2label /dev/sdg5 wd1_p5_avl42

check label

Code:

e2label /dev/sdg5

fix grub installation
==============

Grub does not calculate the "right" boot disk (the name that the bios uses).
When /dev/sdg is booted using the the boot menu from the bios, the bios names are reordered.
sdg and sda are only placeholders!!! check your own config!!!!

So:
normal boot: /dev/sda = (hd0)
/dev/sdg = (hd2)

usb boot: /dev/sdg = (hd0)
/dev/sda = something else

when grub is installed, the "normal" boot/disk order is assumed. This has to be fixed.

fix grub
in root terminal
check if "root" is mounted:

Code:

mount | grep sdg5

if yes umount:

Code:

umount /dev/sdg5

start fix:

Code:

mount /dev/sdg5 /mnt
bind fs to "root"
mount -o bind /dev /mnt/dev
mount -o bind /proc /mnt/proc

copy device.map

Code:

cp /mnt/boot/grub/device.map /mnt/boot/grub/device.map.org

fix device map

Code:

gedit /mnt/boot/grub/device.map

-> make shure /dev/sdg is (hd0)
(hd0) /dev/sdg
(hd1) /dev/sdb
(hd2) /dev/sda
(hd3) /dev/sdh
save

the grub menu is now wrong (hd2,4) should be (hd0,4), (grub partition number 4 is linux partition number 5) check your own configuration!!!

fix menu.lst

Code:

cp /mnt/boot/grub/menu.lst /mnt/boot/grub/menu.lst.org
gedit /mnt/boot/grub/menu.lst

change:
# groot=(hd2,4)
to:
# groot=(hd0,4)

after the comment:
### END DEBIAN AUTOMAGIC KERNELS LIST
add:

title      AV Linux 4.2 Live Image
root      (hd0,0)
chainloader   +1

title AV Linux 4.2 Restore Image
root (hd0,1)
chainloader +1

reinstall grub to /dev/sdg5

Code:

chroot /mnt /usr/sbin/grub-install /dev/sdg5

run "update-grub"

Code:

chroot /mnt /usr/sbin/update-grub

clean

Code:

umount /mnt/dev
umount /mnt/proc
umount /mnt

fix boot flag
=========

make installation bootable.
let the mbr, that was installed with unetbooting boot from /sdg5:
run gparted: choose /dev/sdg: enable boot flag on /dev/sdg5 (, remove boot flag on all other partitions of /dev/sdg)

boot avl from usb hard drive
=====================

set symlinks

Code:

cd
ln -s /media/wd1_p7_data data
ln -s /media/wd1_p6_bkp bkp

install rt-kernel
http://www.remastersys.com/forums/index.php?topic=1162.msg6430#msg6430

use this script to get your usb disk port:
get-usbdisk-port

Code:

#!/bin/bash

#get partition
part=$(mount| grep " / "|cut -c 6-9)
#echo / mounted on $part
pcipart=$(ls -l /dev/disk/by-path/| grep $part|awk '{print $(NF-2)}')
#echo $pcipart
pci=${pcipart%-usb*}
pcinr=${pci#pci-}
#echo $pci
#ls -la /sys/devices/pci*/$pcinr
usbport=$(ls -la /sys/devices/pci*/$pcinr/|grep usb |awk '{print $NF}')
usbdriver=$(ls -la /sys/devices/pci*/$pcinr| grep driver|awk -F'/' '{print $NF}')
#echo $usbport
#echo $usbdriver
#echo "rtirq name: $usbdriver:$usbport"
echo "$usbdriver:$usbport"

setup /etc/default/rtirq
mine looks like this, but i'm not shure if its the best setting.
ehci_hcd:usb1 is the output from the get-usbdisk-port script. hdsp is my sound card.

Code:

gedit /etc/default/rtirq

RTIRQ_NAME_LIST="rtc hdsp ehci_hcd:usb1"
RTIRQ_NON_THREADED="rtc hdsp ehci_hcd:usb1"
RTIRQ_HIGH_LIST="timer sirq-tasklet sirq-block"

cutomize your setup

fix live boot
=========

root terminal

Code:

gedit /media/WD1_P1_AVLL/syslinux.cfg

add to every "append" entry that has the "boot=live" option:
live-media-path=/liveorg

Code:

mv /media/WD1_P1_AVLL/live /media/WD1_P1_AVLL/liveorg

create system backup
=================

preferences -> remastersys backup
Backup - Backup complete system including user data
(this will not backup data partition)

terminal:

Code:

mkdir ~/bkp/some-date
cp /home/remastersys/remastersys/avlinux4.2-liqx-lxde-i386-en.iso* ~/bkp/some-date

make system backup restoreable
=========================

root terminal:

Code:

cd /media/WD1_P2_AVLR/
rm -r isolinux live preseed ldlinux.sys menu.c32 syslinux.cfg ubnfilel.txt ubninit ubnkern ubnpathl.txt

system tools -> unetbootin
diskimage, iso: /home/your-user-name/bkp/some-date/avlinux4.2-liqx-lxde-i386-en.iso
drive /dev/sdg2
ok
exit (no reboot)!!!

remake existing installation bootable !!!:
gparted: /dev/sdg: enable boot flag on /dev/sdg5 (, remove boot flag on all other partitions of /dev/sdg)

fix permissions:
because unetbooting was run as first program after installation?

Code:

su
root@your-user-name:/home/your-user-name# ls -la .config/gtk-2.0
chown -R your-user-name:your-user-name .config/gtk-2.0

restore system
===========

Boot usb drive, grup option "AV Linux 4.2 Restore Image"

preferences -> remstersys installer
continue, yes
continue, ok
select sdg, ok
quit gparted
select sdg3 for swap, ok
select sdg5 for root, ok
select root, put /home on root partition, ok
enter hostname, ok
select root for grub installaion !!!, ok
configure time zone, ok
continue, yes
reboot now?, no !!!

restore fs label
in root terminal
check label

Code:

e2label /dev/sdg5

set label

Code:

e2label /dev/sdg5 wd1_p5_avl42

check label

Code:

e2label /dev/sdg5

fix grub installation

root terminal:
check if "root" is mounted:

bind fs to "root":

Code:

mount -o bind /dev /mnt/dev
mount -o bind /proc /mnt/proc

copy device.map

Code:

cp /mnt/boot/grub/device.map /mnt/boot/grub/device.map.org

fix device map

Code:

gedit /mnt/boot/grub/device.map

-> make shure /dev/sdg is (hd0)
(hd0) /dev/sdg
(hd1) /dev/sdb
(hd2) /dev/sda
(hd3) /dev/sdh
save

fix menu.lst

Code:

cp /mnt/boot/grub/menu.lst /mnt/boot/grub/menu.lst.org
gedit /mnt/boot/grub/menu.lst

# groot=(hd2,4)
->
# groot=(hd0,4)

umount /mnt/dev
umount /mnt/proc
umount /mnt

reboot

That's it.
Hope this works for you.

I run this setup for some time with AV Linux 4.1.
Now I'm updating to 4.2 and I like to share it.

I can do 8 track recordings with ardour. I did tests with 16 tracks, this should work also.
8 tracks worked with liquorix and ardour2, the same session works only with the rt-kernel in ardour3.

YMMV.
