This web-page merely documents what I did to install Gentoo-linux in my Latitude E4300 using the gentoo powered rescue cd by www.sysresccd.org .
It is absolutely not meant to be an installation guide. Anyone deciding to take benefit of informations provided in this page be aware that this choice will be at her/his own risk.Useful installation guides can be found at
During and after the installation I observed systematic locking up of the machine whenever I was using the C-compiler or other cpu-power demanding applications. I contacted assistance and after several unsuccessful intervenctions between December 2008 and January 2009 I received the following statement from Dell commercial:
Issue:After replacing the motherboard with a newer model at the end of February 2009, the locking-up phenomena disappeared. It took however a lot of time...
Regular reviews of Latitude E4300 field performance data as well as a small number of customer escalations have revealed a potential for system hangs in some Latitude E4300 systems. E4300 systems that have this issue will periodically hang and need to be rebooted. This issue can occur when running any OS and on systems using either the SP9300 or SP9400 CPU.
Root Cause:
The root cause is the power level available from the motherboard to the SP9400 and SP9300 CPUs under high stress conditions.
Solution:
Dell recommends that the users who have experienced this issue disable Multi-core on the affected systems until service supply of motherboards is available in mid- February. Dell will work with customers to replace motherboards on these systems as stock becomes available.
The table below summarises the hardware detected on the laptop.

Installation of LVM2 on the volume group in /dev/sda5 |
$ modprobe dm-mod
In order to avoid scanning the cdrom:
$ mkdir -p /etc/lvm
$ nano -w /etc/lvm/lvm.conf
(set filter to scan /dev/sda and reject anything else)
filter = [ "a|/dev/sda|", "r/.*/" ]
To change pre-existing volume group
$ vgchange -a y
I named "vg00" the volume group on "/dev/sda5"
$ pvcreate /dev/sda5
$ vgcreate vg00 /dev/sda5
Had I wanted to include more partitions in the volume group
$ vgextend vg00 /dev/${DISK}7 /dev/${DISK}8 /dev/${DISK}9
Creation of logical volumes in "vg00"
$ lvcreate -L1G -ntmp vg00
$ lvcreate -L10G -nvar vg00
$ lvcreate -L12G -nusr vg00
$ lvcreate -L4G -nusrlocal vg00
$ lvcreate -L3G -nopt vg00
Use vgdisplay to check the remaining space
$ vgdisplay
$ lvcreate -L63.13G -nhome vg00
To list the properties of the logical volume "home"
$ lvdisplay /dev/vg00/home
|
Volume groups, logical volumes can be resized
Resizing with LVM |
$ vgreduce vg00 /dev/sda5
echo "..." give verbose output
$ lvcreate -L800M -nvar vg00 creating var as 800MB
IMPORTANT:
before resizing a logical volume it is necessary to
1) UMOUNT the volume, if mounted.
2) resize the FILESYSTEM if already installed e.g. for home on ext3:
$ umount /dev/vg00/home
$ fsck -n /dev/vg00/home check only that the filesystem is clean
$ tune2fs -O ^has_journal /dev/vg00/home disable journalling
$ e2fsck -f /dev/vg00/home repair
$ resize2fs /dev/vg00/home 64.18G reduce the fs to the desired size
$ lvreduce -L-2G /dev/vg00/home reduce the logical volume by 2G
$ tune2fs -j /dev/vg00/home restore journalling
Detailed instructuctions available from the LVM-HOWTO
and from howtoforge.com - resizing ext3 prtitions.
For EXTENDING a logical volume WITH FILESYSTEM it is necessary to
$ umount /dev/vg00/home
$ tune2fs -O ^has_journal /dev/vg00/home disable journalling
$ e2fsck -f /dev/vg00/home repair
$ lvextend -L+2G /dev/vg00/home enlarge LV
$ resize2fs /dev/vg00/home adapt fs to new size
$ tune2fs -j /dev/vg00/home restore journalling
If the fs is not mounted:
$ lvresize -L400M /dev/vg00/var now 400MB
For enlarging
$ lvextend -L+1G /dev/vg00/var
In order to add 22 more logical extents (4MB each default) 1.4GB+88MB
$ lvresize -l+22 /dev/vg00/var
$ lvresize -L3G /dev/vg00/var
Detailed instructuctions again from the LVM-HOWTO
|
Resizing without unmounting or rebooting: |
$ mount -o remount,ro /boot
after installation is complete to protect that critical data
$ mount -o remount,ro /boot
|
Recovering LVM after emergency reboot (using a rescue cd simplifies (http://www.sysresccd.org/Main_Page )) |
if at boot vg00 is detected
$ /sbin/vgmknodes /dev/vg00
$ vgscan --mknodes (to restart an interrupted Gentoo installation)
|
Applying the filesystems |
$ mke2fs -j /dev/sda1
$ mke2fs -j /dev/sda3
$ mkswap /dev/sda2
$ swapon /dev/sda2
$ for i in /dev/vg00/* ; do mke2fs -j $i ; done
|
Mounting |
$ mkdir /mnt/gentoo
$ mount /dev/sda3 /mnt/gentoo/
$for i in boot usr tmp var home opt proc; do mkdir /mnt/gentoo/${i} ; done
$ mkdir /mnt/gentoo/usr/local
$ mount /dev/sda1 /mnt/gentoo/boot
$ for i in usr tmp var home ; do mount /dev/vg00/${i} /mnt/gentoo/${i}; done
$ mount /dev/vg00/usrlocal /mnt/gentoo/usr/local
$ chmod 1777 /mnt/gentoo/tmp
