HPC RAID array

The storage on the HPC is using a RAID array. (Level?)

It is currently reporting a degraded array (27 Aug 2009):

#cat /proc/mdstat
Personalities : [raid0] [raid1] 
md1 : active raid1 hda1[0]
      129920 blocks [2/1] [U_]
      
md3 : active raid1 hdc3[1] hda3[0]
      2097024 blocks [2/2] [UU]
      
md2 : active raid1 hdc5[1]
      65437696 blocks [2/1] [_U]
      
md0 : active raid0 hdc2[1] hda2[0]
      20971008 blocks 256k chunks
      
unused devices: <none>

To Do list:

Prepare written instructions on how to repair disk arrays.

Add extra spare disks?

How do you know which physical disk is broken to replace it?
