That's what I initially thought ... but got surprised when I reboot the
system. What I initially did was:

1. connect an external maxtor usb hdd.
2. initialize the device (pvcreate)
3. create a Backup volume group (vgcreate)
4. create logical volumes inside Backup volume group (lvcreate)
5. mkfs.ext3 to logical volumes inside Backup volume group.
5. create the mount points (mkdir /var/ftp/Backup/<departament_name> )
6. update /etc/fstab to add mount definitions.
7. mount partitions.
8. fix permissions.

It worked until the system was rebooted. When did so, the system stopped
and prompted me to add root password to correct the filesystem. I picked
the CentOS LiveCD, commented Backup logical volumes definitions in
/etc/fstab and after reboot the system booted up. Once inside the system
checked volumes with lvscan, all lv inside Backup volume group were
inactive.

How could I help ?

Yep. I think so.
