That nasty click is an IDE drive resetting itself. Failure may be moments away. In the hardware RAID you described, it may be a bit harder to isolate which drive is dying ... you may actually have to get your head next to each one to find it. The problem then is that you need to evacuate that PV (which may be the whole array from your description of the setup) and replace the faulty drive. You may be able to take less drastic action, depending upon the capabilities of your RAID card. If you are mirroring, you can also get this if one of the drives in the mirror is slower than the other (also happens if you are striping, but you said that you weren't). While drives can live for months this way, they drag your system performance to the ground and eventually fail anyway. Get out while you can still save your data!
