I'm using ubuntu 12.04.4 Server and this is my current setup:
My hard disks:
wax@petra:~$ sudo fdisk -l /dev/sda
Disk /dev/sda: 1500.3 GB, 1500301910016 bytes

Il disco /dev/sdd non contiene una tabella delle partizioni valida
This is the mdadm output:
wax@petra:~$ cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5]
[raid4] [raid10]
md1 : active raid1 sdd[3] md0[2]
2930135360 blocks super 1.2 [2/2] [UU]
md0 : active linear sdb[0] sda[1]
2930277152 blocks super 1.2 0k rounding
unused devices: <none>
Why sda1 and sdb1 are market as boot? My boot disk is sdc. Also grub is
installed in sdc AND in sda I think that's an error right?
Why sda and sdb have partitions while sdd doesn't?
Is there something wrong with my setup?
