Hi,
With raid device, a failed disk may stay unnoticed for long, if noone runs
a raidctl -s on the device to check the status.
The attached patch checks for failed components in raid devices, and produce
an output like this:
failed RAID component(s):
raid1:
           /dev/sd2e: failed

I've it on several of my machines, and it helped at last one time.
would anyone object if I commit it ?
