Hi,
i've investigated the issue a little more and found some results
that make me think i did something wrong at raid array 
creation time as:

1) using the script in /usr/share/mdadm/mkconf (which uses mdadm --examine --scan --config=partitions) i get 

# definitions of existing MD arrays
ARRAY /dev/md2 level=raid1 num-devices=2 UUID=95261952:6a58368f:9d4deba6:47ca997f
ARRAY /dev/md0 level=raid1 num-devices=4 UUID=2928f68e:5d9adc5b:3fbebe5a:bce56b15
ARRAY /dev/md1 level=raid1 num-devices=2 UUID=e16b4bf9:f0dbce60:04894333:532a878b   spares=2
ARRAY /dev/md1 level=raid5 num-devices=3 UUID=fd0b1c0e:f10deae6:11c6bfd4:055cd56a     spares=1

2) while with mdadm --detail --scan i get:

ARRAY /dev/md1 level=raid5 num-devices=3 spares=1 UUID=fd0b1c0e:f10deae6:11c6bfd4:055cd56a
ARRAY /dev/md0 level=raid1 num-devices=4 UUID=2928f68e:5d9adc5b:3fbebe5a:bce56b15
ARRAY /dev/md2 level=raid1 num-devices=2 UUID=95261952:6a58368f:9d4deba6:47ca997f


So seems that i did something stupid (forgot to delete an array?) that i don't know how to fix at the moment. :-(
It seems to me that the installer uses method 1 rather than method 2, but i can't say
if this is a good thing(TM) or not........

BTW: the arrays seem to work perfectly...

Sorry, for the noise and thanks for your time and response,

Ciao,
Tito
