Buenas gente, hoy instalé ubuntu desktop 10.04 con raid 1 y estoy teniendo
algunos problemas.
1) practicamente al 100% de uso de ram
2) cuando realizo multiples operaciones con los discos o movida de datos
grandes el sistema se cuelga, como esperando respuesta, al cabo de un tiempo
vuelve en si, asumo que por [1]
les paso mi config:
md0 es raid1 entre sda1 y sda1 /boot
md1 es raid1 entre sda6 y sda6 /
md2 es raid1 entre sda7 y sda7 /home
