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?
