</pre>
Nos nodes instale o =sendmail-cf= e replicar a configuracao abaixo:
<pre>
vim /etc/mail/sendmail.mc
define(`SMART_HOST', `[spserv01.sprace.org.br]')dnl
cd /etc/mail
make
newaliases
/etc/init.d/sendmail restart
</pre>
*OBS* foi necessário remover o /var/mail/sendmail* de alguns nodes
   * Servidor de Boot Remoto
Para a instalacao dos nodes usando PXE é necessario instalar
<pre>
yum install tftp-server -y
vim /etc/xinetd.d/tftp
disable=no
yum install syslinux
cp /usr/lib/syslinux/pxelinux.0 /tftpboot/.
mkdir /tftpboot/pxelinux.cfg
chmod a+r  /tftpboot/pxelinux.cfg
cd /tftpboot
vim pxelinux.cfg/default
# timeout de espera
TIMEOUT 10
# Sempre mostrar o prompt
PROMPT  1
# Default e' realizar a instalacão
DEFAULT linux 
LABEL linux
     kernel vmlinuz1
    append ks=nfs:192.168.1.150:/tftpboot/kickstart/ks_32bits.cfg initrd=initrd1.img  devfs=nomount ksdevice=eth1
LABEL boot
    LOCALBOOT 0
</pre>
Dentro desse diretório =/tftpboot= devem ficar o kernel e a imagem initrd que voce deseja bootar (No caso do Scientific Linux, procure no repositório por =images/SL/pxeboot/vmlinuz= e =images/SL/pxeboot/initrd.img=
<pre>
ls /tftpboot/
initrd.img  msgs  pxelinux.0  pxelinux.cfg  vmlinuz 
mkdir /tftpboot/kickstart
cp ks_* /tftpboot/kickstart/.
</pre>
A demora para passar pelo menu do TFTP até o =default= foi corrigida adicionando a seguinte linha no =/etc/dhcpd.conf=
<pre>
 next-server 192.168.1.155;
</pre>

---+++Transformando o raid1 em hd ativo

Deve-se formatar o raid1 da antiga CE. Siga as orientacões abaixo para formatar todas as particões do raid e criar os pontos de montagem.
Ex:
<pre>mkfs.ext3 /dev/md0
mkdir /new
mount /dev/md0 /new</pre>

Copie todos os diretórios para os novos dir. 
Ex: 
<pre>cp -a /boot.* /new/boot
cp -a /opt.* /new/opt</pre>

Não copiar os diretório /sys /proc /dev . 
O /proc é usado para processos correntes apenas, se fizer cópia deste diretório trava o processo de cópia.

<pre>mount -o bind /dev /new/dev
mount -t proc none /new/proc
mount -t sysfs none /new</pre>

O diretório /tmp só não pode ser movido:
<pre>chmod 1777 /new/tmp </pre>

Entre como root no novo servidor:
<pre>chroot /new/bin/bash</pre>

Pontos de montagem e grub
Prestar atencão nos pontos de montagem. 
Editar de acordo com a tabela do original do osg-ce. 

<pre>/new/etc/fstab 
/new/etc/mtab
/new/boot/grub.conf</pre>

Instalando o grub:
<pre>grub_install /dev/sdb
mkinitrd -f /boot/initrd-2.6.X.X.img 2.6.X.X</pre>

O HD antigo da CE será usado para fazer parte do raid da nova CE.<br>
A CE antiga deverá ter seu raid1 totalmente desfeito e remontado para que sincronize com a nova CE e não o contrário.
