Not getting anything from mdadm --examine for raid1 array

Not getting anything from mdadm --examine for raid1 array

[William Colls]

The array consists of 2x2Tb disks, each with a single partition filling 
the whole disk.

If I look in /proc/mdstat I see the following information:

Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] 
[raid4] [raid10]
md0 : active raid1 sdc[1] sdb[0]
       1953383360 blocks super 1.2 [2/2] [UU]

unused devices: <none>

mdadm --detail /dev/md0 returns the following:

/dev/md0:
         Version : 1.2
   Creation Time : Sat Jan  5 12:39:24 2013

   Used Dev Size : 1953383360 (1862.89 GiB 2000.26 GB)
    Raid Devices : 2
   Total Devices : 2

        1       8       32        1      active sync   /dev/sdc


mdadm --examine --scan /dev/md0 returns nothing.

Am I in trouble. If so how bad is the problem, and how best to fix it?

Thanks for your time.

William.

"--detail" is for array devices like /dev/md0

"--examine" is for array members like /dev/sdb

HTH,
