Si tienes uno o mas dispositivos "mdX", es por que tienes RAID. Según veo, tu raíz está en un RAID. Puedes ver que particiones la conforman con el siguiente comando: "mdadm -D /dev/md1".

Si quieres desactivar el RAID(que no lo recomiendo), tendrías que reinstalar el sistema operativo.

Hola !

Yo utilizaria mejor que FDISK la utilidad PARTED ...

Pega la informacion de ...

~# parted -l

... informaacion de particiones


~# cat /proc/mdstat

... informacion RAID


~# pvs
~# vgs
~# lvs

... informacion LVM de los volumenes fisicos


Salu2.

Hola:

He adquirido este servidor: http://www.soyoustart.com/es/ofertas/e3-ssd-2.xml
Y me viene con esta configuración (pego abajo).

Tengo 3 SSD se supone, pero ¿ sólo tengo 120Gb porque están en RAID ? No entiendo esa configuración.

Si tengo más, ¿cómo puedo usarlos?

GRACIAS !


Código:
# fdisk -l
