If you hover your mouse over the disk you should see some stats.

Your logs show that disk 3 (one of your WD20EARS disks) has failed. It has 945 reallocated sectors and a current pending sector count of 695. I would suggest replacing this e.g. with a WD20EFRX.

Your smart_history.log would suggest this disk was failing possibly as far back as April. Certainly by May/June.

Do you have a backup?

Degraded means there is no raid redundancy, so any disk failure will result in loss of the volume.

How many volumes do you have? (with xraid you'd only have one).

Do the SMART stats for your disks look fine?

Can you send in your logs (see the Sending Logs link in my sig)?

  Thanks mdgm,
  
  Just sent you my logs via email.
  
  Not sure what the Smart stats are for the disks? Apart from the yellow 'degraded' alert, there is nothing else in any interface that looks like a problem?
