Do we return to the attack with the granduyón, in the last post we remain just to begin the installation, have the CD truth? since forward!

As soon as the portable one was started, we will have ahead a bare commands line … the first thing that we must do is to form the network, if it is that we do not have clear DHCP in our network. If our network has automatic directions allocation, as in my case, we will not have to worry about anything since netplugd he will take charge of everything. If we have no DHCP, we will have to form the network using the assistant or to hand, as let's want: Si no tenemos DHCP, deberemos configurar la red usando el asistente o bien a mano, como queramos:

livecd ~ # net-setup eth0

Being still the assistant we will have the network formed concerning a few seconds.

Particionando the disc …
To work with the disc we will use cfdisk, we are going to create two divisions, the first one will be of 512MiB for / boot and the following one of approximately 120 – 130GiB that it will serve to us to create a VG. We will leave some free GiBs to lodge the swap out of RAIDs and LVMs: why? everything patience will come.;) todo llegará paciencia….;)

Is it already time to take this M$ Vista from us of above, that we are going to install? Gentoo! And because? you can ask that … well it is with the distro which more comfortable I meet. I realize that portage since implementation is not the best of the world, for example, it might be more rapid … but good inside the imperfection that we might find in any software as our needs, Gentoo for me is perfect Y porque? podeis preguntar…pues bien es con la distro que más comodo me encuentro. Soy consciente de que portage como implementación no es la mejor del mundo, por ejemplo, podria ser más rápido…pero bueno dentro de la imperfección que podriamos encontrar en todo software según nuestras necesidades, Gentoo para mi es perfecta

What is the idea?
Making use of two discs of the HP Pavilion dv9890es let's mount the system with the discs in RAID-1 (mirror, mirror …) thus we will have all the resulted information and in case of casque of 1 disc ….estaremos brans! But do I remember that to have the discs in RAID-1 is not a stand-in of the safety copies OK? As the yankees would say, shit happens or what comes to be … (from slightly more polite form) everything can go on since a RAID-1 does not protect us from human mistakes, I even remember that time mounting a RAID-1 for software that I was wrong of division and remained without / home that precisely wanted to answer! Como dirian los yankees, shit happens o lo que viene a ser…(de forma algo más educada) todo puede pasar ya que un RAID-1 no nos protege de fallos humanos, aun recuerdo aquella vez montando un RAID-1 por software que me equivoqué de partición y me quedé sin el /home que precisamente queria replicar!

To part of the RAID-1 we will mount LVM, which will allow us to manage the space of our divisions of a more comfortable form in case that we lack in some place.

How do we start?
The first thing that we are going to do is to lower an iso minibadly of gentoo for amd64, if I do not remember badly Gentoo a stable iso does not publish from 2008.0-r1 so we will look for a mirror with autobuilds, that are not any more than iso done of a form automatic and published to have anything more recent than the official version.

The advantages of these autobuilds are basically that quite what they take it is much newer, what I was walking looking is to have a recent kernel during the installation and not to find me with problems of absence of drivers of network, SATA, etc …

Good as we speak about as to extend a filesystem in AIX now is the HP-UX shift.
To start we will verify that we have available space in the VG:

# vgdisplay vg10g
— Volume groups —
VG Yam/dev/vg10g
VG Write Access read/write
VG Status available, exclusive
Max LV 255
Cur LV 3
Open LV 3
Max PV 16
Cur PV 1
Act PV 1
Max PE per PV 2812
VGDA 2
PE Size (Mbytes) 64
Whole PE 2812
Alloc PE 1740
Free PE 1072
Whole PVG 0
Whole Spare PVs 0
Whole Spare PVs in uses 0

We return to the attack with AIX … this time we will see like extending a LV and managing to have more space of available storage.

What és a LV?

A LV would come to be the equivalence to a division inside a conventional disc. The LVs are parts of a VG and a VG it is only a set of discs that for the system is as if they were the only one. That is to say we can have a better management of the space. Es decir podemos tener una mejor gestión del espacio.

To sum up, a VG is a set of discs, for the operating system it is as if it was only one unit inside which we can create divisions or rather LVs.
