sembra un raid non attivo ... mandaci l'output di cat /proc/mdstat quando il
server è su con il raid attivo

Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4]
[raid10]
md0 : active raid1 sdb1[0]
      387696512 blocks [2/1] [U_]

 e anche quando hai solo sda

poi meglio se ci invii anche un blkid con raid attivo
