Problemas y dudas con arreglos de disco

Problemas y dudas con arreglos de disco
« on: January 18, 2008, 10:26:55 PM »
ya he leido bastante pero no he encontrado respuestas.

Estoy usando SME Server 7.3

I.
cuando ejecuto lo siguiente:
mdadm -E --scan

Obtengo como respuesta:

mdadm: ARRAY line /dev/md2 has no identity information.
mdadm: ARRAY line /dev/md1 has no identity information.
ARRAY /dev/md2 level=raid1 num-devices=2 spares=1 UUID=d33169f5:00abaed5:c2941c1e:46211eed
ARRAY /dev/md1 level=raid1 num-devices=3 UUID=53e85b14:ffac9732:b00871c8:1c42555e
ARRAY /dev/md2 level=raid5 num-devices=3 UUID=240bffb5:85382531:a65c7eae:5672a9a1

lo que me parece muy raro ... ya que el dispositivo /dev/md2 aparece con 2 tipos de raid

el archivo mdadm.conf tiene solo lo siguiente:
DEVICE partitions
ARRAY /dev/md2
ARRAY /dev/md1
===========================================================
II.
lo otro es que en el dispositivo /dev/md1 tengo 3 unidades
       0       8       17        0       active sync   /dev/sdb1
       1       8        1        1       active sync   /dev/sda1
       2       3        1        2       active sync   /dev/hda1

pero si reinicio siempre se desconecta /dev/hda1 , y tengo que volverla a unir al arreglo.


Si alguien me pudiera ayudar o explicar que es lo que sucede lo agradecería.

Incluyo trozo de log que considero podría ayudar.
