I've got a pair of 1TB drives on my Debian fileserver set to RAID 1 using a PCI controller, but it doesn't want to mount them.

If I do a blkid the drive doesn't show up, but I know (from using cfdisk /dev/sdb to create a partition) that the drives are working.

lshw -class disk -class storage gives me the following info about the array:

  *-storage
   description: SATA controller
   product: 88SE9123 PCIe SATA 6.0 Gb/s controller
   vendor: Marvell Technology Group Ltd.
   physical id: 0

      size: 931GiB (1TB)
      capabilities: partitioned partitioned:dos
      configuration: ansiversion=5 sectorsize=512

I'm properly stuck now - I mounted a USB drive in /etc/fstab with no trouble, but this one refuses to play ball. Does anyone have any idea what I can try next?

I suppose you are meaning Hardware RAID there. So the question is what happens if you try to format (fsck) the partition you created? –  Envite Nov 26 '13 at 15:40

Excellently, after posting this question I managed to do it (isn't that always the way?).

For whatever reason cfdisk wasn't partitioning the drives. Using mkfs.ext3 /dev/sdb5 sorted the drives out and then I could mount it in fstab.

Thanks to anyone that gave it some thought.
